Re: Label volumes in a scsi library?
Joni, The SENSE information is described on page 78 of the Quantum SCSI Reference Guide for the Scalar i6000 byte –code = description 0 -70 = Response Code 1 -00 = reserved 2 -05 = reserved or sense key 3-6 are all zeros = information 7 - 0a = additional sense length (0a indicates the media changer control path is hosted by a DA blade controller and sends 10 bytes of data ) 8-11 are all zeros = command specific information 12 -21 = additional sense code (ASC) Invalid Element Address in CDB (See table 78 on page 80 of the Quantum SCSI reference guide) 13 -01 = Additional sense code qualifier (ASCQ) 14 -00 = FRU code 15 -cf = SKSV,C/D,Reserved,BPV, or bit pointer 16 -00 = field pointer 17 -06 = field pointer It looks like you are trying to move the tape to an invalid location based on the ASC code.

Re: confused about deduprequiresbackup
See page 286 in the AIX admin guide Quote: Attention: By default, the Tivoli Storage Manager server requires that you back up deduplication-enabled primary storage pools before volumes in the storage pool are reclaimed and before duplicate data is discarded. The copy storage pools and active-data pools to which you back up data and copy active data must not be set up for data deduplication. To prevent possible data loss, do not change the default. If you do change the default, reclamation criteria remains unchanged ... ... Attention: You can change the default setting to permit reclamation of primary storage pools that are not backed up. However, there is a remote possibility that changing the default can result in unrecoverable data loss if a data-integrity error occurs. To change the default and permit reclamation of primary sequential-access storage pools that are not backed up, set the value of the DEDUPREQUIRESBACKUP server option to NO. Changing the default does not change the reclamation criteria that you specified for a storage pool. The DEDUPREQUIRESBACKUP server option applies only to primary storage pools. The option does not apply to copy storage pools or active-data pools. Cheers, Thank you, Neil Strand Storage Engineer - Legg Mason Baltimore, MD.

Re: Ang: [ADSM-L] Backupset restore question - different server OS's
Yes, things tend to move quickly around here and I might be attempting to use TSM in an unconventional manner. I have to move about 90 TB of data from data center A to Data center B. The data centers have dissimilar SAN storage and very limited WAN connectivity between each other. Each server at the new data center will be a new system and needs to be seeded with data from the currently running system. Some servers will only require a few GB of seed data while others will require several hundred GB and a few have several TB of seed data. I have to have a data migration solution ready next week and should begin migration shortly after Labor Day. My Plan in a nutshell: 1. Generate a backupset on a TSM V5.5 AIX server on encrypted 3592 media at data center A 2. Ship the encrypted media to data center B 3. Define a backupset and generate a backupsetTOC(optional) from the encrypted 3592 media on the TSM v6.2 Linux server at Data center B. Data center B has the appropriate encryption keys to decrypt the media. 4. Restore backupset data to the appropriate client from the TSM V6.2 Linux server at Data center B - No TSM DB Upgrades required or planed. The TSM V6.2 Linux server is a fresh install. There are two methods of performing a backupset restore - 1. Attach client to media containing the backupset data OR 2. From a TSM server containing backupset data. (Ref: TSM for AIX V5.5 Admin Guide - pg 454). I plan to perform the second. I plan to move the backupset data from server to serverB as described in TSM for AIX V6.2 Admin Guide pg. 520 as such there should be no issues with DB differences between TSM V5 V6 unless the data written to the backupset media is significantly different. I also ran across IC62418: Backup set and Table of Contents support in Tivoli Storage Manager Version 6.1 which discusses backupset compatibility between V5 TSM servers and V6.1.2 or higher TSM servers in the Problem Conclusion section. Since I have not built the Linux TSM server yet, I cannot test the compatibility of the 3592 media written by AIX and then read (hopefully) by Linux and this has me concerned. It looks like a backupsetTOC is not required but would be nice to have. Your comments are welcome. Thank you, Neil Strand Storage Engineer - Legg Mason Baltimore, MD.

Re: TSM Recovery log is pinning since upgrade to 5.5.5.0 code
Eric, Regarding TSM as being the right product. You may want to assess it as part of your entire storage infrastructure and the services this environment provides to the business and end users. Last year I had an issue that almost resulted in my having to recover several (~30) TB of user data (many millions of files). During the initial phase of the problem, we initiated a TSM recovery to an alternate device, just to get the recovery started in the event we couldn't resolve the issue. What did save my bacon was the data being mirrored to another device that I brought online. We were able to resolve the issue and everything was returned to normal. This event caused me to really look hard at our backups. Had we really needed to recover all of that data from tape, we would have been down or partially operational for a week or so. I am using 18 TS1120 drives in a 10 frame dual robot TS3500 library and IBM P550 TSM servers with 4Gb SAN connections - not cutting edge but still pretty good stuff. Currently, I do not rely on tape backup for large scale recovery. It can be accomplished, but the RTO (for large amounts of data) is unacceptable for normal business operations. For NAS data, I use snapshots for short term RPO (2weeks) with mirroring to protect from disaster. Tape recovery fits in between these two scenarios to provide recovery for older data (more than 2 weeks old) and for long term archives (7 years). Production devices with SAN or local storage are mirrored using the OS or DB tools and also backed up but the tape backup is a secondary recovery mechanism to the OS DB tool recovery and also provides for long term archive. In general, as we become more virtualized and RTO requirements shrink to minutes, the amount of data to recover grows to terabytes and the number of files to recover is rounded to the nearest 1/10 of a million, tape recovery becomes ineffective for large recovery scenarios and the only alternative is snapshot or mirror recovery methods. Tape still offers a cost effective long term archive solution and can provide a bridge for recovering older data that is not in a snapshot. It also provides an alternative storage device to store data and should not be affected by OS or application bugs or malicious software - kind of a failsafe device (assuming the backup processes are successful). Eventually, we may go to a cloud based backup solution if it proves to be operationally and cost effective and secure. Cheers, Neil Strand Storage Engineer - Legg Mason Baltimore, MD.

Re: Find Lost Files
Brian,
You may be looking for a file in a directory that has the same name
as a filesystem.
Assume that /var is a filesystem with a directory named /var/junk
and has been backing up for a few years. Someone comes along and
creates a new filesystem named /var/junk and mounts it over the
directory /var/junk. Backups continue for some time. Now someone
wants a file restored from /var/junk when it was a subdirectory in the
/var filesystem.
In order to restore a file from the FILESYSTEM /var/junk, you would
perform a regular restore. Since they want a file from the DIRECTORY
/var/junk, you would need to look in the /var filesystem for the
/var/junk directory. To specify the /var filesystem, you need to
enclose the filesystem variable in the query with braces query backup
{/var}/junk/lostfile. If you don't enclose the /var in braces, the
query will run against the /var/junk filesystem and you will never see
the file needing restore.

Yes, I selected inactive files in the GUI.
Maybe someone knows a way I can query where the file is. I suspect the

Re: Windows servers with a kazillion files and Win2K8...
Wanda, If it is a 32 bit system, the most memory that can be addressed is 4G. 2^32 = 4,294,967,296 bytes 4,294,967,296 / (1,024 x 1,024) = 4,096 MB = 4GB Moving to a 64bit system would allow additional memory to be fed to the beast. If the windows servers are not running the application but simply providing filespace to the application that is running on another server, see if the following is possible: - Implement DFS and provide a virtual tree that is composed of multiple physical data repositories. Each repository could be backed up using a proxy - recovery may be a bit convoluted, but possible. Identify the problem not as a backup problem but a data management problem that requires some level of granularity to be introduced to the environment.

Re: copypool-only TSM server on a VM
Keith, A few thoughts Putting a TSM server on a VM may have advantages in performing a quick recovery of the TSM server in the event of a corrupted DB or other nasty event. Not sure how DB2 would integrate with VM snapshots but it sounds interesting. If you are backing up VMs or data located on the same VM host as the TSM server VM, are you really protected or just practicing backups with no real intention of performing a restore when there is a serious problem? Throughput will probably be your biggest obstacle and may consume most of the resources on the VM host. Have you considered several TSM instances on a non-VM server with the same beefiness as your proposed VM host? It sounds like someone is trying to get you to save a nickle or two and squeeze a few CPU cycles out of a TSM server to share with an application server. If you put the TSM server on a VM host that also has a largish DB and depend on production timing to share resources, you may run into a resource conflict when either environment runs slightly out of it's 'normal' production window causing a death spiral for both environments.

Virtual machines on ESX can't do I/O to tape devices, but the source server for a server-to-server copy pool does not need to do I/O to tape devices. It sends its files to the target TSM server which does the tape I/O. So, potentially, several TSM servers built on virtual machines could send virtual volumes to one physical TSM server target with tape I/O capability. Primary pools would be defined on the source servers, but they would be marked unavailable permanently. Each TSM server on a virtual machine would have two copy pools: one on-site and the other off-site; instead of an on-site primary pool and an off-site copy pool. The reason for doing this would be; to divide the backup load into smaller chunks across more TSM servers, to avoid buying more physical servers, and to share tape drives without using a Library Manager. A detriment of this setup would be that reclamation of the copypools would be degraded with no primary tape pools to read from. Are there other obvious or subtle problems with this idea? Or, is it brilliant?... Which copypool would restore files come from? How would that be managed? Our TSM license is based on TB in primary storage, so extra licenses are not a factor.

Re: Tivoli TSM replacement options
Tim, You may want to approach the problem from the opposite direction. Consider your recovery needs and available options and work from there to determine what product/technology/processes meets your objectives. Trying to recover a few TB of data within a couple of hours is nearly impossible unless you use snapshot or mirroring. However the snapshots only protect you from a subset of problems. Mirroring data similarly allows quick recovery but also has its limits on protection. You will probably want to consider how several data protection methods (i.e. snapshot/mirror/backup and archive) can be integrated together to provide a cost effective, environment for protecting your data and ensuring business needs are achieved.

I thought perhaps the Performance Tuning Guide would help clarify, which is where I thought I read this. But it seems somewhat ambiguous. Here are some snippets (for AIX): When AIX detects sequential file reading is occurring, it can read ahead even though the application has not yet requested the data. * Read ahead improves sequential read performance on JFS and JFS2 file systems. * The recommended setting of maxpgahead is 256 for both JFS and JFS2: ioo .p .o maxpgahead=256 .o j2_maxPageReadAhead=256 then later on the same page: Tivoli Storage Manager server - Improves storage pool migration throughput on JFS volumes only (does not apply to JFS2 or raw logical volumes). and still later: This does not improve read performance on raw logical volumes or JFS2 volumes on the Tivoli Storage Manager server. The server uses direct I/O on JFS2 file systems. So which is it? Does it read ahead on jfs2 or not? One vote for and 2 against. On later on, there are a couple of related to using raw LV's which mentions array-based read-ahead: Using raw logical volumes on UNIX systems can cut CPU consumption but might be slower during storage pool migrations due to lack of read-ahead. However, many disk subsystems have read-ahead built in, which negates this concern. Clear? eh. What I take away from this is if your array supports read-ahead, make sure you've got it enabled - at least for storage pool LUNs. Probably doesn't make sense for DB LUNs, as it will just waste your precious cache. ..Paul .. thinking I might need to spend a few more nights at Holiday Inn Express .. At 03:43 PM 10/20/2010, Remco Post wrote: Hmmm, that's interesting, jfs2 read-ahead. I know it exists, but recent TSM servers by default use direct I/O on jfs2, bypassing the buffer cache, and I assume the read-ahead as well... Or am I wrong? I noticed that on an XIV, dd can read a TSM diskpool volume at say 100 MB/s, and yes two dd processes, reading two diskpool volumes get about 185 MB/s, not exactly twice as much, but much more than one process. The same is true for TSM migrating to tape. So, even though you'd think that two processes would appear more random than one, the XIV is still able to handle them quite efficiently. Yes, this is two processes working on a single filesystem from a single host. Now, of course, dd doesn't use direct i/o, and TSM does, but still, there is a noticeable benefit to running two migrations in parallel, even if both are on the same lun, filesystem, etc. (Yes, on jfs2). On 20 okt 2010, at 21:28, Paul Zarnowski wrote: yes, this can get complicated... Yes, multiple threads accessing different volumes on the same spindles can create head contention, even with volumes formatted serially. But I think you can still reap benefits from laying down blocks sequentially on the filesystem. Remco points out read-ahead benefits, and he is (IMHO) referring to disk array-based read-ahead. Keep in mind that jfs[2] also has read-ahead, and it will still try to do this
Re: Lousy performance on new 6.2.1.1 server with SAN/FILEDEVCLASS storage
There should be queue depth settings for individual disks and for the HBA on the server - not on the Array. The sum of the Disk settings should not exceed the setting for the HBA. By EMC voodoo I meant the EMC management application that allows you to monitor the performance of the array - I'm not sure what it's proper name is. As Remco pointed out check with the EMC folks and your HBA vendor and OS support to determine queue depth limitations. Seems like I ran across a combination for AIX or Solaris attached to either an older FastT or NetApp that defaulted to a depth of 1 and required a firmware update to fix.

Re: Looking for SAN/tape experts assistance
The zoning process simply associates a server HBA port on the server with the HBA port on the disk device. Persistent binding is a function of the OS and HBA drivers on the server. Within the server configuration, the HBA must be told that a device with a particular ID (i.e. /dev/rmt1) is always to be associated with a physical device with a specific ID (i.e. WWPN). This is typically performed by a configuration file that manages the HBA configuration. On Solaris with an Emulex HBA, the file /kernel/drv/lpfc.conf will allow you to manage persistent bindings by associating a specific WWPN or WWNN to a specific scsi ID: e.g. fcp-bind-WWPN=500a098386f7d4f3:lpfc0t0; You also need to ensure that automatic reconfiguration is NOT set. Automatic reconfiguration can be particularly vexing in a fiber channel loop environment where device contention may cause indeterminent delays with multiple target devices (tape drives) attached to a single initiator (server HBA).

My name is George Blackwood. I was a Systems Engineer with IBM for 30 years. Among other things, I was a SAN, tape, and TSM specialist. I have been retired for 2 years, 1 month. I have my own consulting business doing what I did when I was an IBMer. When Linux is rebooted (RedHat, SLES, whatever), it will scan and re-discover its SCSI and FCP (Fibre Channel Protocol) tape resources without regard of what it knew about those same devices before the reboot (this is not the case with some UNIX systems). So, unless you have one changer and one tape drive, you have no guarantee that the Linux device numbers will be the same after reboot. So, chances are IBMtape0 will be IBMtape20 the next time you reboot. IBM's answer is to set SANDISCOVERY ON. This works sometimes for a small number of drives (under 20), and will sometimes work for more. But after 18 months of being in and out of IBM PMRs and CritSits, I have given up on sandiscovery to fix this issue. I wrote a BASH script to fix this issue. A current customer of mine has 8 RedHat Linux servers sharing 12 TSM instances (we can move them around as need be). Two instances are Library Managers. All instances have access to 4 EMC EDLs. Each EDL has 80 drives. So that comes to 3890 drives paths, plus 4 Library paths to maintain. The script I wrote discovers what TSM instances (Library Servers and Clients) are running on a given Linux server that has just been rebooted. It compensates for any drives that may be mounted, or any Libraries that are in use, and re-defines all the Library and drive paths for any TSM instance on a given Linux server. So if one of the 8 servers needs to be rebooted, the script is run on that server after reboot. There is no need to unmount and quiesce Libraries. The only requirement is the Library Managers must be up. The script will also find what drives are in a SCSI reserve lock out. And, it is safe to be run during full production time. I can give you a few pointers to write a similar script (for free), or for a fee, write it for you. I guarantee my work.

With the server doing nothing but migrating data from this SAN based stgpool to TS1130 tape, I am seeing roughly 700GB being moved in a 12-hour period. On my other, internal disk based TSM servers, I move multiple-terabytes per day/24-hours. So, where should I focus on why this is so slow? Is it because I am using SAN storage? How about the FILEDEVCLASS vs fixed, pre-formatted volumes (like every other server is using)? Or is this normal? If it is, I am in for some serious problems. One of these servers is expected to replace an existing 5.5 server that processes 20TB+ of backups, per week (no, I can not go straight to tape due to the type of backups being performed).

Re: Feature or bug?
If you define a bug to include flawed logic or reasoning then yes - this is a bug. It demonstrates a level of shallow thought usually associated with toys and simple games where there are a small, finite number of outcomes. If you define a bug along the line of Adm. Grace Hopper's reference - as something that causes destruction, then no, this is not a bug and is a simple feature. Cheers, Neil Strand Storage Engineer - Legg Mason Baltimore, MD.

Re: TSM and XIV
Something we have noticed is that when an AIX server is zoned to the same FC port(s) on the storage device as a windows or Linux server, the AIX server tends to have reduced throughput when both servers are accessing the storage.

Re: Need to understand TSM restoration concept.
Cc, An important consideration in restoring a file is understanding the retention settings of a copygroup and the distinction that two settings affect HOW MANY copies of a file are kept after they change or are deleted and two settings affect HOW LONG files are kept after they are changed or deleted. VERExists - how many copies VERDeleted - how many copies RETExtra - how long to keep RETOnly - how long to Keep If a file never changes or is never deleted from the client, it will be restorable as long as it is not deleted from the TSM server - a nice benefit of the incremental forever method. As a general rule, for general filesystem backups, I keep all versions (VERE VERD) but set limits on how long (RETE RETO) deleted and changed files are kept. This way, if a couple of files are constantly changing, I can reliably roll back to any date within the retention time and restore any file. Again- this setting is something that varies with each environment. It may take a while to understand these settings and how they interact, I would suggest that you set up a test policy with short settings to observe how things work.

Re: single drive restore possibilities
Depending on the size of the restore, you might consider replacing the single tape drive with a small NAS disk device with deduplication such as a Data Domain, Quantum or Netapp. This device could be configured to contain an active data pool for the MC servers as well as a backup of the TSM database. Just make sure that the restore location TSM server has an identical OS as the primary location. If this device has extra space, it could also be used to provide a temporary backup repository at the offsite location until a tape library is set up.

TSM Server migration
I have a TSM V5.5 server on AIX. I need to get all of the data to a Windows or Linux TSM environment on x86. Export node will work well for everything EXCEPT a NAS node (you have to really love these little caveats and exceptions). A backup/restore or unload/load will probably fail due to big-endian/little-endian incompatibilities between the architectures. Does anyone have any recommendations for getting the NAS node data to the new server? I am thinking that I will have to do a full restore to a spare NAS device and then back it all up again. The current server is idle and the new destination server has yet to be built so it is wide open regarding linux/windows, TSM V5/V6 - I can pretty much do what I need to do to get this data moved (goodness knows that I shouldn't do what I want to do...gr!)

Re: FILE Device class over NFS
I did some NFS testing last year: = Test 1: I wanted to determine the feasibility of using a Deduplication device that was NAS attached to the server Equipment TSM V6 on AIX6 DataDomain - DDR510 1Gb Ethernet I was using 2GB File devices on an NFS mount from the DDR as primary pool Data Transfer speed was acceptable for testing but was not an objective of the test. Deduplication was around 46% for a couple of Windows workstations and the TSM server. Test2: Can I run an entire environment on NFS rather than Fiber Channel? Equipment TSM V6 on AIX5.3 NetApp 3040 using 250GB SATA drives and deduplication 1Gb Ethernet 2Gb fiber Channel Test - TSM 5.5 upgrade to V6.1, InsertDB operation for 4GB TSM Database Fiber Channel = 9122MB/hour NFS = 7491MB/hour - The entire TSM environment EXCEPT the binaries configuration files were located on NFS. This allowed for simple and quick DB backup and recovery using snapshots through the DB2 interface. - Deduplication of the DB was significant but the small test data set I was using may not have been representative of an operation environment. == Conclusions: - NFS may be viable for some environments and may actually be preferable to local or SAN storage. The simple protection offered by DB2 integrated snapshots can provide that extra level of protection that lets you sleep well. - If you don't have a SAN infrastructure, and don't want to build out a bunch of local disks, the NFS is easly scalable. This testing only applied to an AIX environment. - Deduplication performed on a NAS device is probably superior to the native deduplication of TSM. The TSM server does not have to spend CPU and memory and the TSM database does not have to track it. I stress again - Wanda's trueism - Your Mileage May Vary. You have to know your environment and determine what best fits. I will soon migrate my V5 environment to a couple of 750GB V6 databases and I am hesitant to put it all on the bleeding edge.

Re: FILE Device class over NFS
My current environment consists of 2 physical locations separated by 200 miles. Each environment has a TS3500 with 10 frames. 10 TS1120s in one library, 16 TS1120s in the other. Both sites have a TSM library manager, the smaller site has a total of 4 TSM servers, the larger site has a total of 9 TSM servers. Average daily backup at the larger site is 5TB. I am thinking of setting up a parallel TSM environment with only 2 physical servers and using export/import to move the individual clients. I am undecided at this point on upgrading the existing library managers or logically splitting the libraries and setting up a completely parallel environment.

Re: Database corruption
Eric, I ran into a similar problem 2 years ago - Corrupted DB. Fortunately, I had a spare server that I quickly set up and moved all backup operations to that server. It took a few days to run through the DB fixes on the corrupt server. After the DB was fixed, I just did server-server exports of all of the old data to the new server. If your test server can temporarily handle the load, you may be able to run backups to it for the 3 or 4 days it takes to fix the corrupt DB and then swing everything back to the original server using server to server exports.

One of our servers have database corruptions. An audit of a copy of the production database restored on our test environment revealed them. Since we do not know the impact of these errors (can all client data be restored, can I restore all primary volumes in case of a restore stgpool?) I definitely like to fix these errors. I ran a AUDITDB ARCHSTORAGE on this server, but that does not fix them, only a full audit does (I have proven this on the test server). The problem is that a full audit runs for 60 hours and I cannot afford a 60 hours downtime. Most of our Oracle and SAP clients haven't got enough achivelog space to survive. I tried several things to trick TSM like create a snapshot on production, immediately followed by a full backup, then restore the snapshot on the test server, perform the full audit on this copy and than create a full backup on the fixed database. This way both fulls have the same sequence number, so I was hoping I could then restore the fixed copy on the production server and apply all incrementals made on the production server. Bad luck, TSM apparently stores timestamp information about previous full backups as part of the incremental backups: ANR4651E Restore of backup series 1733 operation restore is not in sequence; backup is part of another log epoch. Explanation: During a DSMSERV RESTORE DB, a backup volume was mounted that is not in the correct sequence. The current backup operation cannot be restored in this series because it belongs to the same backup series from another point in time. Bummer... The only thing I can think of now is making a snapshot copy and restore it on the test server, perform a full audit here and freeze ALL housekeeping processes on the production server. On the production server perform an EXPORT SERVER FILEDATA=ALL FROMDATE=TODAY-1 FROMTIME=NOW every day at the same time. As soon as the audit finishes on the test server, create a snapshot and restore it on the production server and import all export volumes created. Am I missing anything or should this work? Import as well as export are single processes, so performance can be an issue here... Thank you very much for your replies in advance!

Data conversion Unix-Windows issue
I have a client which would like a copy of their backup data in the least expensive form and capable only of restoring - no future backups to TSM are required. Currently their data is backed up to an AIX server attached to a TS3500 library with TS1120 drives using TSM 5.4. Backups have ceased but the existing data has a 3 year retention and there may be a need to restore data. I need to get their data out of my Library and free up my AIX server for other purposes. My recommendation is to purchase a small windows server with a single SAS attached encrypted LTO4 drive and export from the AIX server to the windows server. The Windows server will sit in a corner and be powered up in the rare event that a restore is needed within the next 3 years. I am 99.9% certain that this (export from AIX- Import to Windows) is the only cost effective course of action available but thought I would check with those (you) who are more versed than I with TSM in a Windows environment - I only have the AIX environment to work with. Questions: 1. Is a DSMSERV DUMPDB from AIX/ DSMSERV LOADDB to Windows an option? 2. Will a windows server be able to read a tape written by an AIX server? 3. Is there another cost effective option?

Snapdiff with NetApp OnTap 7.3.3
FYI. For those who use the TSM client snapdiff functionality to backup their CIFS shares on a NetApp filer, I have been advised of the following which affects those who upgrade their NetApp to the latest O/S - OnTap 7.3.3: If you have any customers using the snapdiff functionality to backup CIFS/NFS shares via the Tivoli Storage Manager (TSM) client please be advised that when upgrading to ONTAP 7.3.3 the TSM client will cause an abort with the backup operation complaining about an invalid ONTAP version. This is not a particular ONTAP version that TSM is complaining about, it is the fact that the API element has been enhanced with the FileAccessProtocol. The work-around for this is to have the customer place an entry ( TESTFLAG SNAPDIFFONTAPFAP ) into the dsm.opt file that resides on the host. This option will bypass the check that looks for the enhanced API that supports Unicode. This will be addressed in a later TSM client version but is needed today for customers moving to ONTAP 7.3.3.

Re: Snapmirror to tape
Sam, If you are backing up a CIFs share, I would encourage you to investigate the -snapdiff option run from a windows server. This will create a snapshot of the volume on the filer and then you only backup the snapshot (or what has changed since the last snapshot) - like an incremental backup on steriods. The first time you perform a -snapdiff, there will be no difference form performing a normal incremental, but subsequent -snapdiff backups should be significantly faster than a normal incremental. There will be no noodling through the filesystem to see if a file has changed because in the snapshot all the files are changed files. Cheers, Neil Strand Storage Engineer - Legg Mason Baltimore, MD.

Re: DataDomain VTL
Howard, I have a pair of DDR410s and pair of DDR510's that are configured for NFS. The 510's are being used to store vRanger backups of a VM environment. Compression/deduplication is incredible for this application. 47TB(terabytes) are stored on 811GB (Gigabytes). Now realize that there is a lot of redundancy with VMs and this environment does not experience a lot of change, but the ability to store 30+ days worth of full backups of 30 or 40 VMs on less than a TB or storage, approaches the cost of tape (excluding electricity). The 510 and 410 models are out of date and I have not messed with the VTL configuration so cannot speak to that specific feature. Configuration is relatively simple. Performance is nothing to brag about for these models (except the deduplication/compression), The one drawback is that a couple of filesystem reconfiguration tasks require taking the filesystem offline. The systems have been running for several years with only an occasional disk replacement. OS upgrades are relatively straightforward - outage required. I did some testing with TSM using an NFS mount. TSM was configured to use the NFS mount with FILE device class with 2GB files. My intention was to compare DDR deduplication with TSM deduplication. I never got back to testing TSM deduplication but the DDR deduplication was 281GB stored on 58GB = 80% savings. Now this data was from a handfull of windows workstations, so there was a lot or redundancy in the data. Generally, I found the DDRs simple to set up, reliable, maintainable, and do what they are supposed to do - crush bits together into the smallest possible space. Performance is good - just don't expect a screaming fast system - at the low end. The high end systems and newer systems advertise greater performance.

Re: Does TSM support 3-way NDMP backups?
Shawn, You can set up NDMP backup destination to a TSM server via ethernet which is nice in that the data can be put in a regular storage pool and an offsite copy created. You can also set the NDMP backup destination to a tape drive(s) physically attached to a filer. I suspect that you may also be able to use SAN shared tape drives if your TSM server is configured as a library manager. I am using the first configuration - data txfr through ethernet to the TSM server with good results. Another option that makes CIFS share file restores simpler (compared to NDMP restores) is to set up a windows box which performs the backups using the -snapdiff option. If your virus scanning servers perform this backup function, they serve a dual role and don't have to scan every file as it is backed up.

Re: Does TSM support 3-way NDMP backups?
I think there may be a lack of clarity with the reference to the link that Tribe provided. Does TSM support 3-way NDMP backups as described here? http://www.ndmp.org/info/faq.shtml#9 As I understand it, the TSM server is the NDMP client, the filer is the NDMP DATA server which then directs it's data stream to the NDMP TAPE server (not a NAS device) The NDMP TAPE server can be a process internal to the filer (to local tape) or the the TSM server (acting as a NDMP tape server). I may have the client, data and tape server components mixed up but this is the general idea that seems to work for me when opening ports through firewalls to make a NDMP backup of a filer. This is also why I like using the windows proxy with the dsmc -snapdiff option for backing up CIFS shares. It is a lot less confusing for my two brain cells to deal with.

Create holes in data
I have a question - please do not ask for an explination - it is what the customer wants. Environment: -TSM Server 5.4 on AIX -TSM BA client on Linux, Solaris and Windows (various flavors) -TS3500 tape library with TS1120 drives (+1TB on each tape) The customer desires me to convert the last couple of years of backup data - all of which has 3 year retention - to look like periodic full backups. - Data between 1 and 6 months old - only the end of month backup - Data older than 6 months - only one backup at the end of the year Similar to a traditional backup where fulls are periodically taken The customer's data from their 160 clients occupies nearly 500TB of tape space (primary only) and is looking to cut down on the number of tapes that they would be required to purchase. This will be a one time effort since the customer is now performing their own backups and I would like the customer to take custody of this legacy data. One thought is to create backup sets of each client at the specified points in time. Your ideas are appreciated. Thank you Neil Strand Storage Engineer - Legg Mason Baltimore, MD.

Re: JR-LAn-Free Restore
JR, Another method of determining if lan-free is working is to perform a query mount on the lan-free client. You can do this from the TSM server console using server to server communications to the client: storageagentname: q mount The data being restored must be accessable from the storage agent. It may be that after backup, the data was migrated to devices not accessable to the storage agent. Cheers, Neil Strand Storage Engineer - Legg Mason Baltimore, MD.

Re: Windows TSM server 6.1.2.0 after clean install : ANR2968E Database backup terminated. DB2 sqlcode: -2033.
Stefan, From the TSM V6.1 Problem Determination Guide - GC23-9789 Note - Adjust the following for your Windows environment == DB2 SQLCODE -2033 SQLERRMC 406 SQL error message code 406 requires that the following issues are resolved: - The DSMI_CONFIG environment variable points to a valid Tivoli Storage Manager options file. - The instance owner has read access to the dsm.opt file. - The DSMI_CONFIG environment variable is set in the db2profile. The following procedure is an example process for debugging DSMI environment variable errors on a UNIX platform where the SQL error code (SQLERRMC) of 409 was displayed when using the dsmapipw command: 1. Open the /home/tsminst1/sqllib/userprofile file and examine the statements. If you make any changes to this file, stop and restart the DB2 instance so that the changes are recognized. The userprofile file might have statements similar to the following example text: export DSMI_CONFIG=/home/tsminst1/tsminst1/tsmdbmgr.opt export DSMI_DIR=/usr/tivoli/tsm/client/api/bin64/dsm.sys export DSMI_LOG=/home/tsminst1/tsminst1 The file in the first line of the example (/home/tsminst1/tsminst1/ tsmdbmgr.opt) might have something similar to the following text: SERVERNAME TSMDBMGR_TSMINST1 The file in the second line of the example (/usr/tivoli/tsm/client/api/bin64/ dsm.sys) might have something similar to the following text: SERVERNAME TSMDBMGR_TSMINST1 commmethod tcpip tcpserveraddr localhost errorlogname /home/tsminst1/tsminst1/tsmdbmgr.log 2. Verify that the SERVERNAME entry in the tsmdbmgr.opt file matches the SERVERNAME entry in the dsm.sys file. 3. Run the DSMAPIPW command. You must be logged on using the root user ID. 4. If you can run the DSMAPIPW command, remove the /home/tsminst1/ tsminst1/tsmdbmgr.log file while still using the root user ID to eliminate permission problems between the root user and tsminst1. Also make sure that the user running TSM has write permissions to all log files The API Options file in UNIX is /usr/tivoli/tsm/client/api/bin64/dsm.sys - look for or create a similar file on your server Another reference you may want to consult is the IBM Redbook: Backing up DB2 with IBM Tivoli Storage Manager - sg24-6247 Cheers, Neil Strand Storage Engineer - Legg Mason Baltimore, MD.

Re: Dedupe
Ditto on Lindsay's it depends For my NetApp devices, observed NAS filesystem dedupe renges from 10% to 70% depending on the data. VMware NFS shares typically show a good ratio. We for our VM environment, we split our OS apart from data and paging space as depicted below: Filesystem usedsaved %saved /vol/PROD_VM_OS/98314436227793716 70% /vol/PROD_VM_PAGING/3107084 1090756 26% /vol/PROD_VM_DATA1/ 1125390017343096 61% /vol/DR_VM_OS1/ 105852808 236518940 69% /vol/DR_VM_DATA1/ 431134632 216285060 33% /vol/DR_VM_PAGING1/ 35520 427211% The paging space is very dynamic and I don't expect much savings. The OS space (where VM operating systems are installed) is relatively static and redundant and reflects that with high dedup ratios. The data space (where applications and everything else is) has a wide variance - as expected. But the end result is that I am saving disk space and actually improving overall performance because redundant data has a higher probability of residing in cache and the reference to a particular bit of redundant data has a higher probability of residing in the cached lookup table. If you are looking for dedupe on tape media, I don't think it is feasable nor desired. Simple compression now allows me to put nearly 3TB on a single 3592 tape (again depending on the data). At a nominal cost of $150/tape this results in about 5 cents/GB. Not too shabby. I make a second offsite copy of the same data resulting in an overall cost of 10 cents to provide +five nines probability that my company's data is recoverable for the next 6 years. This is less than the cost of electricity for disk based storage for the same time period. Dedupe has it's place as do most technologies. It is not a golden egg unless you force it to be ... and then, when it hatches, it may be a fine goose or it may be a platypus - it depends on your environment.

It is usually to reduce data on disks. One concern would be the amount of tape mounts required to restore data in the event of a DR scenario. As the article has stated there are not many global de-dup products yet. We have been able to implement some dedup on specific applications, for instance E-mail attachments and it has worked out fairly well. However, it primarily was to reduce the size of the Storage Groups of our Exchange cluster, in the event of a DR scenario, which is on tier 1 storage. And the de-dupped attachments are now on tier 2. It reduced our SGs by 1/3. The exchange SGs backups are retained based on legal requirements and replicated. The attachments are not. I also tested Data Domain and was very unimpressed by the numbers I saw. It had very little impact on our largest amounts of data. Imaging, Exchange and DB dumps.

Re: Backing up running VM's
TSM license is for the hardware platform. So, if you have 5 VMware servers, you need 5 TSM licenses, no matter how many virtual servers you have running. A 4 processor, quad core license is more expensive than a 2 processor, single core license, but, TSM/IBM does not care how many servers are virtualized on it. And IBM will gladly ignore their falling revenue stream and not revise their licensing because they are just really nice and know that nearly free backups will solve world hunger. I have a cousin in Bangledesh that needs to transfer $2,000,000 out of the country by next week. He needs a bank account to send it to. If you would kindly provide your bank account and social security number, he will share 1/2 of the money with you. Please phone him at 1-800-scr-ewme to make arrangements. Have a nice day!

Re: NDMP backup of non-qtree data
Ken, If the N-series is providing CIFs shares, you should consider backing up with a windows server mounting the shares and then using the -snapdiff option in TSM V6 client. This greatly simplifies recovery as it is nearly identical to regular client recoveries. NDMP backups are full/differential and do not take advantage of the incremental forever philosophy of TSM. If you are using LUNs mounted to a database server running DB2 or Oracle you may want to look into TDP for Snapshot Devices/TSM for Advanced Copy Services. With NDPM backups, you must specify a specific file name to backup. Wildcards are not accepted. If you take a snapshot you must create the virtualfsmapping to that specific snapshot name. E.g. define virtualfsmapping netapp1 /exc1_sg1_logs.snap__recent /vol/exc1_sg1_logs /.snapshot/exchsnap__recent *Note the full path name to the snapshot file exchsnap__recent in the virtualfsmapping. This file MUST exist in order to perform a backup. I think you would have difficulty backing up the non-qtree portion of a volume because this would imply a top level backup which would contain the sub level q-trees by default. You may be able to specify the volume and use exclude statements to ignore the q-trees. It looks like it can get pretty messy on the restore though. You probably also want file level recovery so be sure to define a TOC storage pool for the NDMP backup Cheers, Neil Strand Storage Engineer - Legg Mason Baltimore, MD.

We are running TSM 5.5.2.0 and using the Filer-TSM-Library method of NDMP backup (storing the backups in TSM native storage pools). It is not practical to backup the entire volume in one shot, but backing up the individual qtrees via BACKUP NODE is manageable. The problem that I have is how to specify backing up the non-qtree portion of the volume. The NetApp commands use a trailing dash after the volume name to indicate non-qtree data (ie: /vol/xyz/- ) however BACKUP NODE complains of an invalid parameter when I use that convention. I tried setting up a virtualfsmapping with the trailing dash and it is accepted for the mapping, however the subsequent BACKUP NODE process fails after it starts with an ANRD catchall: Error beginning NDMP backup - illegal arguements.Check that the filespace/path '/vol/xyz/-' exists.

Re: Snapdiff option with V6.1 Windows client
Paul, NDMP uses a full/differential method which does not fit well with our long retention requirements. Running daily differentials with a weekly full on 30TB of data would fill my library in less than 100 weeks with no consideration for any other backup data. The process for performing a restore was also a bit more complicated that a simple BA client restore. Currently our file level restores take a few minutes - very acceptable - and are performed identically as a regular server file restore. Snapshot schedule: - every 4 hours keeping 24 hours -(RPO = 4 hours for the first 24 hours) - nightly keeping 5 nights - (RPO = 24 hours for 24 hrs data 5 days) - weekly keeping 2 weeks (not too usefull but it satisfies other peoples perceptions) We also mirror data once a day (more frequent for critical data) to a remote site. TSM provides the long term retention we need and fairly quick assisted data recovery. Users have the option to recover recently deleted data from snapshot or request assistance from our support team. Full scale failover to the remote site filer takes a few minutes. If the -snapdiff option improves backup times as I hope, I will be able to eliminate the weekly snapshots (saving disk space) and should be able to provide a firm 24 hour RPO for all data as well as a firm sync point. Currently, backups begin and run for about 26 hours (noodling through millions of files - not a data throughput problem) and there is no guaranteed point in time recovery because the files backed up at 8pm monday may change by the time other files are backed up at 10am Tuesday (during the same backup session).

Re: TSM 6.1 Installation Problems
Grigori, If deduplication is your driving force, you really need to evaluate if a VTL or NAS appliance may be a better solution for your environment. There are several out there and some have evolved to provide primary storage dedup. I agree that the massive increase in resources is troubling but, compare current hardware with what was available when TSM V4 first came out. TSM is not for small environments - it is an enterprise solution which requires enterprise resources. The evolution to DB2 was desprately needed not only to help contain TSM server sprawl but to also allow more resources to be dedicated to improving TSM functionality rather than maintaining the old TSM database. I currently have 16 AIX TSM servers in 2 locations and am planning to consolidate to between 4 and 8 servers each having a bit more hardware than the current servers. I will be able to do this because the database will be stable above 500GB. I realize that backups will take a bit of time but hopefully IBM will implement parallel backup processing and I will be able to backup a 1+TB TSM DB in less than 2 hours and restore it in less than 5. Del Hoobler, If you have some input to TSM evolution, please consider a command line switch or server setting which would allow multiple parallel backup and restore processes for the database - similar to what can be done in IBMs Data Warehouse environment.

I think this is coming together with DB2. I was not able to install TSM 6.1 in manual mode. I have used GUI assistant to complete all tasks. In my opinion, it is not good, because I am not a beginner in TSM (10 years!); 2) TSM 6.1 requires much more disk resources. Database is much bigger (not only +40% declared in documentation). Using de-duplication + reclamation produces 2-3 times more logs. In addition, new requirements came for archived logs. Usually archived logs are bigger than logs. There is automatic cleaning procedure for archived logs, which requires 2 or 3 full backups of database. As a result, archived logs are kept at least for 3 days in case of using full backup for database every day. Just imagine if you are using weekly full backup for database!!!???. Note I did not use mirroring for logs and archived logs. With mirroring it will be full crash at all from disk space requirements; 3) TSM 6.1 requires much more CPU and memory resources than TSM 5.5 and not only for de-duplication. During testing I am running backups and copies without de-duplication (numpr=0) and than de-duplication + reclamation after completion of backups and copies. In addition to dsmserv process there is db2sync process which is usually much heavier than dsmserv; 4) I have found very strange TSM behavior during some commands like delete volume ... discarddata=yes. Command reports successful completion, but process is still running with heavy load from db2sync. I am not sure, but it can be a bug. I hope this information will be interesting for TSM admins.

Re: Backup files to empty tape
Mario, You have several options 1. generate backupset . Scratch=no vol=x - This allows a client to restore directly from the media or from another TSM server - self contained allows data mobility to another TSM server or directly to a client - tape and data not tracked in TSM - only contains active data 2. export node Scratch=no vol=x - This will create a copy of all of the client data that can be imported to another TSM server - self contained - allows data mobility to another TSM server - tape and data not tracked in TSM - all data (active and inactive) may be included 3. Create a primary storage pool to dump only this client's data in it. Then define a copy pool (maxscr=0) and assign a specific volume to that copy pool. Backup the primary pool to the copy pool backup the primary pool and use movedrmedia to eject the copy pool tape. - allows you to manage the data normally using TSM Your choice depends on what you are attempting to accomplish.

Re: Dear Tuscon
Tom, If you have more than one TSM server you can have multiple copies of the same backup just by using virtual volumes to another TSM server. - Backup to virtual volume on server A - storage pool A - Create offsite copy of storage pool A on server A - Create a second copy if you are really paranoid or have poor tape reliability. If your virtual volume is on RAID disk, it is probably a bit more reliable than most tape. If you really want to get fancy, put the virtual volume storage pool on mirrored disk and immediately after the backup completes, break the mirror and you have two instant copies of your DB backup.

Re: Transfer/transition netbackup data to TSM
Geoff, To add to Wanda's point #6 regarding recoverability in 10 years. It is relatively simple (but time consuming) to transfer old data to new media by simply creating a storage pool for that new media and running a move data command. If you upgrade to a new TSM server, it is also simple (but takes a bit of time) to move data from the old server to the new server attached to media incompatible with the old server with the export node command. That will leave only the recovery target operating system and application to worry about in 10 years (after you devine the current TSM licensing conspiracy). The incremental forever methodology takes a bit getting used to if you come from the Gf-F-S world, but once you really sit down and think about long term recovery with no data holes, it really fits nicely.

I have customers that are seeing data growth of more than 50% per year; with the growth in non-text data (video images) and the cost of storage dropping rapidly, 50% growth per year is probably on the low side. In this environment, it just doesn't make sense to adopt a technology that requires you to do repeatedly send data that hasn't changed across your network. 3) If you are involved with a grandfather/father/son backup technology, there are holes in that system. Typically people who use non-TSM backup software do something like weekly fulls and daily incremnentals. The fulls go into the vault a some point, say monthly for a year. If you have a file that is created on a Tuesday, and accidentally deleted on a Thursday, after a few months you have no backup copy of that file because it isn't on a full dump tape. TSM won't let that happen: if you are supposed to have backups of that file, you WILL have backups of that file. GF-F-S backup softare manages tapes. TSM manages your data. 4) By using TSM incremental-only, you get a no holes backup system (i.e. better backup coverage) and you use less media (therefore less$$) to do it, because you don't need full dumps. 5) TSM DRM gives you a recovery plan, you don't have to create it yourself. 6) The most important and least-advertised feature of TSM ( I think because the sales folk seldom understand the difference): Not all data has the same value to the organization. I don't need to keep backups of Windows executables forever; I need legal records 7 years and I need patient data lots longer. With increasing regulations regarding records retention (SOX, HIPPA, general liability, etx.), it's more important than ever to recognize and enforce retention rules properly. TSM lets you treat different data differently; you can assign different backup frequencies and different retention rules to different data, based on its value and retention requirements.

Re: Setting up crossbackup datacenters with TSM
Rolf, I am sure the tape library can handle the data load. Where most problems happen is in the communications between the data centers. If your data centers are 200KM apart and connected by a 1Gbps link, your bottleneck is the WAN link due to latency, cost and competition with other data transmissions on that link such as normal client operations, device mirroring operations and database operations. In this case you will want to take a very hard look at what you are attempting to achieve and consider options such as increasing data mirroring between storage devices for protection and then backing that mirror up locally. You could also do as others have recommended recommend, as do I - backup locally and ship copy media offsite with the TSM server DB backup both locally and to the remote site using virtual volumes. If your datacenters are close - i.e. 100M, and connected on you local ethernet and there is no competition for bandwidth between the buildings with other devices, you should have few problems with a normal setup. You would also want to backup the TSM server DB to the other TSM server in this case also. Cheers, Neil Strand Storage Engineer - Legg Mason Baltimore, MD.

Check using: lsdev -Cc tape To enable alternate pathing (From IBM TotalStorage and System Storage Tape Device Drivers Installation and User's Guide - GC35-0154-17) command: /usr/lpp/Atape/instAtape -a This will unconfigure all devices that have alternate pathing set to No, and will reconfigure all devices, setting alternate pathing to Yes. To enable or disable the support on a single logical device, use the smit menu to Change/Show Characteristics of a Tape Drive, then select Yes or No for Enable Alternate Pathing Support. The support can also be enabled or disabled using the chdev command, for example: chdev -l rmt0 -aalt_pathing=yes chdev -l rmt0 -aalt_pathing=no Cheers, Neil Strand Storage Engineer - Legg Mason Baltimore, MD.

Re: TSM library problem caused by IBM3584 virtual I/O

We have a library master instance, and 9 other TSM instances that are library clients. They all share an IBM3584 with 24 LTO4 tape drives, and an EMC EDL virtual library emulating an IBM3584 with 128 LTO1 drives. Recently our IBM CE told us we should be running with virtual I/O, a feature of the IBM3584 library. The reason he recommended it is because we frequently have more than 32 outgoing tapes every day, and sometimes the Operators don't get around to taking the tapes out of the I/O doors, and checkouts have to wait. With virtual I/O turned on, the checkouts go ahead and run to completion, even though the tapes don't actually go into the I/O doors. Then later when the I/O doors get empty, the tape library moves the rest of the tapes into the I/O doors. That part seems to be working as expected. After we turned virtual I/O on, we started getting weird symptoms in TSM, like tapes that we would check back in to the library, but later TSM could not find them. So we decided that maybe virtual I/O changed the element number map, and we should have redefined the library to TSM. So we: 1) Deleted the drive paths, drives, library path, and library on the library master instance, and all client instances. 2) From the Tape library Web interface, performed a complete library inventory (just in case) 3) Defined the library, library path, drives, and drive paths on the library master instance, and all client instances. 4) Checked back in the scratch tapes 5) Checked back in the private tapes 6) Did an Audit library on the library master and all library clients. It was only a few days later that we started getting errors from TSM of the form: 09/04/08 22:00:56 ANR8300E I/O error on library SUN2079 (OP=6C03, CC=314, KEY=05, ASC=3B, ASCQ=0E, SENSE=70.00.05.00.00.00- .00.0A.00.00.00.00.3B.0E.00.C0.00.04., Description=The source slot or drive was empty in an attempt to move a volume).

(SESSION: 395703, PROCESS: 487) It is different tapes every time, so we now have over a dozen tapes that are missing on account of this. Did we do something wrong with we turned on virtual I/O for this library? I found this technote, that sounds like it is supported. It also says we need to restart the TSM server instance, which we have done now a couple of times since this problem started. With SAN Device Mapping implemented (since TSM520 for Windows and TSM530 for most other platforms), when hardware changes are done to the library, the Tivoli Storage Manager server needs to be restarted. During server initialization, Tivoli Storage Manager server will access the library. If the library inventory has changed, it will be refreshed at that time. If drives are added or deleted from the library or drive element addresses are changed, this information will be refreshed at server initialization also. If the library path has changed, then the path needs to be updated with the new device name for the new library path. The same holds true when dealing with a 3584 library with the ALMS feature. This is discussed in the following document : http://www-1.ibm.com/support/docview.wss?uid=swg21053638 That document will mention that TSM supports the Advanced Library Management System (ALMS) and Virtual I/O Slots (VIOS) features of IBM 3584. When changing the number of drive, storage, or import/export elements for a logical library, the TSM server must be restarted. Is there something else I needed to do in TSM? Some option in the
Re: TSM Administrative Tasks
Curtis, I'm not sure if these fall into managing a system category, but they are things that I have dealt with on a periodic basis. Customer service - Gary calls and leaves a voice message asking for a restore of the file veryimportant.txt in his home directory because he accidently deleted it. A quick search of the files backed up do not show that file and a voice mail to Gary asks him to confirm the file name. He responds that the file may have been deleted some time ago - not sure when, but he is sure it was there last month and it may be called something else - If we could just restore everything, that would be fine. Working with Management - Can you explain to management in 5 minutes the different data retention settings and how they interact with each other? - Can you explain why and how TSM may maintain two copies of data in primary and copy pools and why you shouldn't just eject your primary pool tapes to save library space rather than purchasing additional library space? - Demonstrate to management why the incremental-forever methodology of TSM is superior to the Daily/Weekly/Monthly methodology of other data recovery products.

Re: LTO4 encryption in an I2000?
Speaking of encryption, I noticed a wonderful little readme on IBM's software download site regarding TS1120 firmware levels and encryption posted on July 18th. ftp://service.software.ibm.com/storage/3592/ See the D3I1_D16.readme.pdf file = Snippet from the PDF When using IBM System Storage TS1120 tape drives with Application Managed Encryption with the Tivoli Storage Manager server, data may not be encrypted with a unique, non-trivial key. Who is affected All IBM TS1120 drives with specific drive firmware levels noted below utilizing Tivoli Storage Manager servers with Application Managed Encryption (AME). TSM is configured for AME when DRIVEENCRYPTION=ON is set for a device class in the TSM server. The TS1120 affected firmware levels and their release date are as follows: * D3I1_C13 - 08/15/2007 * D3I1_C15 - 09/04/2007 * D3I1_C91 - 11/13/2007 * D3I1_C93 - 12/05/2007 The TS1120 firmware level that resolves the problem is as follows: * D3I1_D16 - 07/18/2008 (or later release) Note on other Encryption options (Who is NOT affected) TS1120 drive encryption users with any other method of encryption (e.g., System managed encryption (zOS), Library managed encryption) are NOT affected by this problem. Therefore any TS1120 encryption user with an attached Encryption Key Manager (EKM) is NOT affected. TS1120 drive encryption users who are not using TSM are NOT affected. TS1120 drive encryption users using TSM but not using the specific referenced drive firmware levels are NOT affected. == Cheers, Neil Strand Storage Engineer - Legg Mason Baltimore, MD.

Re: AW: [ADSM-L] Export / import nodes with shared library
Otto, After you export using the server to server method, verify that all data has been successfully imported to the target TSM server. Then delete the node and all of it's data on the source TSM server. The volumes holding the deleted data will have free space. The volumes can then be reclaimed through normal reclamation or move data commands. Nothing needs to be performed on the TSM Library manager. For a short period of time you will need two times the number of tapes because the data is fully duplicated on both the source and target TSM servers.

Re: IBM p 520 vs. p 570
The p550's work well. They have better I/O expansion than the p520 and are less expensive that the p570. When you are specing out your system, keep in mind the throughput of your tape drives and add I/O if your budget allows. The p550 also makes it easier to physically relocate a server where with an LPARd p570, you are stuck with a single physical box. I have four p550s each with two LPARs, two I/O drawers attached to SAN tape drives and internal disks for the OS and TSM DB and disk pools. They are relatively simple to maintain and were a more cost effective solution than a p570 with multiple LPARs. Cheers, Neil Strand Storage Engineer - Legg Mason Baltimore, MD.

Re: TSM being abandoned?
I looked at the TSM V6 beta and found there will be a license module
that determines how many licenses your system will need. After a bit of
debugging and reverse engineering, I obtained a snippet of the source
code - Now remember, this is beta, so it may or may not make it into the
shipping version:
$pvu = int(rand(1000));
If ($pvu 900) {
print Server License Compliance: Valid\n;
} else {
print Server License Compliance: Invalid\n;
}

No, but you will have the option to stay with tsm v5.5 at least until
tsm 6.2 has been released. My bet is that since 6.1 is a really big
step (redesign, reimplementation of major parts of tsm), 6.2 will not

Re: TSM being abandoned?
The VTL can compliment a TSM installation where you have a real tape library (RTL) manager and RTL clients. Adding a LAN-Free agent to a RTL client is greatly simplified when the RTL client is also attached to it's own VTL. The RTL client can be the library manager for the VTL and share the virtual drives to the LAN-Free agent(s). With several LAN-Free agents, a VTL can easily be provisioned to provide additional virtual drives without impacting the RTL. Cheers, Neil Strand Storage Engineer - Legg Mason Baltimore, MD.

Re: Drive Encryption (3592)
Boris, Library managed encryption is controlled by the TS3500 library communicating with the Encryption Key Manager application and TSM has no awareness of any encryption occurring. No TSM configuration is required when performing library managed encryption. I strongly recommend that you review the the following: IBM Encryption Key Manager Intro, Planning and User Guide (GA76-0419) IBM Tape device Drivers Encryption Support (GA32-0565) IBM TSM Building a Secure Environment (Redbook SG24-7505) IBM System Storage TS1120 Tape Encryption: Planning, Implementation and Usage Guide (Redbook SG24-7320) IBM Tape Encryption for TS1120 and IBM Ultrium 4 Tape Drives (TechDoc, Rolf Hahn) Plan to spend a few weeks setting up your key management, testing and documenting key management policies and procedures. Also verify the recovery procedure if you accidently loose or destroy a key (hint - monster.com) An advantage to library managed encryption is that your security group can be respoonsible for managing the encryption keys with almost no TSM expertise required. Additionally, a different application (not TSM) could write encrypted data to a tape with no dependence on TSM (other than temporarly marking that drive unavailable and ensuring the tape is not a TSM tape). Have you considered encrypting every tape in the library? It may simplify your media management. The performance hit of encrypting on a TS1120 is almost nill.

Re: TSM for a Disaster
Joni, Should be fine. Just make sure that your device class points to the manual library. You may want to test a small scale DR recovery by creating a DR primary and copy pool and putting a single node's data in it and then test recovery offsite with this subset of data. If you have a library manager/client relationship defined, you will need up run upd server forcesync=yes on both the lib manager and client. If yo have both systems (production and DR) operating simultaneously, you may want to revise the port numbers on the DR system (and clients which attach to it) to prevent any accidents - i.e. if production is 1500 change DR to 2999. Just think, in a year or so, when TSM V6 uses DB2, you will have to re-engineer your replication environment to integrate TSM DB2 with SRDF. There is tons of cooperation between IBM and EMC so this should be a breeze. Have a nice day! Neil Strand Storage Engineer - Legg Mason Baltimore, MD.

This is a library that is managed by one server with two additional servers as library clients. I checked the volhist on each server and the only one it shows up on is the library manager. If I check this tape in as private, it shows one of the library clients as the owner of the tape, yet there is no volhist for it and the tape is not recognized on that TSM server. It seems the only option left is to assume there is nothing on the tape and label it with an overwrite. Does anyone else know what to do with a tape like this? (Unfortunately, I seem to have about 30 tapes in this condition.) I've seen that in the recent past. In library manager/client environments, there is the occasional orphaned tape.

The TS3500 library is my favorite library out there; it is even more durable than the 3494, MUCH faster, and a cleaner interface than the 3494 (no category codes to deal with). In considering libraries, keep very much in mind the distinction in types, and relative advantages. The 3494 concept is very clean: it contains a library manager and database, where the host needs only ask it for a tape mount, and not be concerned about keeping track of tapes. The 3584 and similar libraries (of the SCSI library legacy name) shift the burden of control to some host program, which has to deal with micro-managing all the volumes, cells, and drives, with a plethora of element numbers. Hopefully, all of these library types will evolve toward some middle ground which combines all the advantages, but allow differing cartridge types.

Re: Backing up PST files
Setting up NDMP is almost a trivial task when using TSM V5.4 and NetApp filers. There is no device driver set up on the filer - just enable NDMP. Schedule snapshots if you want to backup a snapshot for a specific time. Create two primary storage pools (one for data one for the table of contents of the data) and a copy pool on the TSM server (disk, tape - your choice), create a datamover and node and virtualfsmapping for that node if you will be backing up snapshots, volume subdirectories or Qtrees. Create a schedule that runs the backup node... command. If you need to recover a single file from a NAS share, the table of contents will allow you to pick that file out and restore it. Use the Windows WEB client - not the installed GUI to see the NDMP node data. You can recover data another filer simply by creating a volume on that filer and updating the datamover address to the destination filer - and then running restore. Yes it places TSM into a relatively simple data repository since you cannot control versioning of specific files, and you have to be aware that the backups will be full or differential but, for some environments, this setup provides needed backup with minimal impact on the TSM database and does not require filling the ethernet with CIFS/NFS traffic to backup from a remote node. It can also be used to backup LUNs that have been snapshot, greatly reducing the impact of backups on the hosting system. The previous requirement of attaching tape to the filer and creating special storage pools that could not be copied goes away with TSM V5.4 and NDMP over ethernet. For some environments NDMP over ethernet is worthy of consideration. Cheers, Neil Strand Storage Engineer - Legg Mason Baltimore, MD. (410) 580-7491 Whatever you can do or believe you can, begin it.

Re: TSM performing full backups where incremental specified
Kevin, Have you verified that the MODE parameter of the copygoup is not set to Absolute? Neil Strand Storage Engineer - Legg Mason Baltimore, MD.

I have followed up the suggestions made, but so far no success. Richard, I checked to make sure that nothing was strange with the filespaces. I actually did an incremental from the command line, then followed it up immediately with another, and sure enough almost all the files backed up twice. DSMC Q FI shows just one occurrence of each defined filespace, so I don't think anything is happening to them between backups. In this case, it would have had to have happened in about one minute. Q BACKUP on the client shows multiple instances of each file -- one active, the rest inactive. I don't see anything on the details of each file that indicates a change. Last access date, file size, all appear identical. I chose several operating system files that I know have not changed since the last server upgrade (more than a year ago) and they still back up when using INCREMENTAL by itself. The number of files backed up is just a few dozen short of the number inspected - a difference which is attributable to those files that were open (such as log files) and could not be backed up. Obviously, with full backups running each night, my tape count in increasing dramatically. I have run traces, and have a call open with IBM. It has been open for 20 days. They are stumped as well, and have no idea what to do. So, I was trying this avenue again in the hope that someone else may have seen this. -Original Message- From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED] On Behalf Of Richard Sims Sent: Monday, January 28, 2008 5:43 PM To: ADSM-L@VM.MARIST.EDU Subject: Re: [ADSM-L] TSM performing full backups where incremental specified Kevin - Heck of a problem you have there. I don't do z/OS or Netware, so unlikely that I'll have an answer, but some thoughts... This is too obvious, but: The filespaces involved are not in some way being renamed or deleted in between the mass incrementals? That would cause a full backup. Seems very unlikely to me, but one thing I would consider. Does a 'dsmc q fi' show a singular instance of the suspect file system? Here I'm thinking of some oddity causing the server to believe that the file system is different each time. But, tape consumption would cause this to stand out. In the backup log, does the number of objects backed up equal the number inspected? If a substantive difference, I would look into the exceptions to see what's the basis of their immunity. Also, perform a 'dsmc q ba -detail -ina ___' on one of the files and see if all versions look the same, or there is some different which might incite the backup. And, if you don't see a bunch of versions, it may be possible that some mutation to the policies is causing obliteration of what was backed up the last time. As a last resort, I would run a client trace of your partial versus unqualified incrementals and see if any functional differences stand out in causing the mass backups. If nothing apparent, give TSM Support a call. wacky stuff I can think of, Richard Sims IMPORTANT: E-mail sent through the Internet is not secure.
