Re: schedule of SQL LOG backup
Hello Luc, I think the only way to do this from the TSM scheduler is to define three schedules, one with a start time of 00:00, one at 00:20 and one at 00:40.

Re: Duel tape write to LTO's
Hi Milton Yes, we are successfully using the COPYSTGPOOLS feature. We have large Oracle and DB/2 database backups going directly to tape. The stgpool has the COPYSTGPOOLS feature set, which resides in a different library, even on a remote location(we're using 9310 with 9840B as the primary tape stgpool and 9310 with 9840C as copypools located 20km away from the main office). During the backup process, if a mount request is denied or there aren't any idle drives in the copypool, the backup will continue, removing the copypool temporarily from the primary tape copystgpool list. This all depends on the parameter CONTINUECOPYONERROR which is also set on the primary stgpool. If you set this parameter to YES, the backup will continue, not requesting any more mount points in your copy storage pool. If you set this parameter to NO however, the backup will either go into mount wait status, or fail, depending on why it cant get a mount point in your copy storage pool. Remember, this feature is only available on LAN-based backups. It is still not available for LAN-free backups, something I think is strange as the largest backups are using the LAN-free functionality. We managed to reduce the amount of data being backed up by the BACKUP STGPOOL process to 40%. If you dont use any LAN-free clients, this feature should be able to completely remove the need for backup stgpool. I do however recommend running the process, event if it doesnt backup any data. Its always good to know that ALL your data resides in the COPYPOOL. I do not recommend using this feature on your primary diskpools. It will only mean that every backup session that is started from your clients, will need a mount point in your copy storage pool. This is a good way to make all clients come in to mount wait status or a good way of needing more drives.

Excessive SCSI media errors
Been having some problems with our Dell Poweredge 136T library with LTO drives lately, we've been getting alot of bad media errors (ANR8944E) and sparodic I/O errors (ANR8302E). There is about 6 of our LTO tapes at the moment which have been experiencing in excess of 180 read errors each, and occassionally they have hung reclaimation or storage pool backup processes forcing the reboot of the server. Several of our other tapes have one or two read errors attributed to them as well but not to the level of some of the others. Looking back at the activity log, the errors primarily occur on DRIVE0 and DRIVE1 in the library (4 LTO drives in total installed). I've run a AUDIT VOLUME on a couple of the tapes and damaged files were encountered. Drives 0 1 do not have their cleaning lights illuminated and they get cleaned every two weeks or when required. The library's and LTO drives firmware are at the latest releases supplied by Dell. The Eventlog for the TSM servers has some of these errors reported in it: The description for Event ID ( 3 ) in Source ( AdsmScsi ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. The following information is part of the event: \Device\mt1.2.0.3, Locate Block ID, DD_DRIVE_OR_MEDIA_FAIL. The device, \Device\mt1.2.0.3, has a bad block. I'm unsure whether this is a symptom of our drives needing a service or perhaps our tapes are getting a bit worn as most have been stored in the library for the past 3 years and used regularly. Anyone had similar problems in the past?

AW: disk storage pools and windows compressed file systems
Hi Steve, i think ist better to use the client cpu for that task to save disk space and cpu at the tsm server. That also reduces networkload for backup and restore. We use compression at the client on all tsm clients including TDP for SQL for a long time. The load during backuptime is typical low, so we can use the cpu for that task without problems. We are quite satisfied with the performance of that solution. Regards Stefan Holzwarth -Ursprüngliche Nachricht- Von: Steve Bennett [mailto:[EMAIL PROTECTED] Gesendet: Dienstag, 21.

Re: D2D on AIX
Good questions. Our real world example:We went from around 8 - 12 GB/hr restore off of tape to over 40 GB/hr from the file device classes. Our test was a file server with a little over 300 GB of data. The File server and the TSM server both had 1 GB NIC's. Resource utilization was set to 10 in both cases. The data was fragemented on tape for a little over a year for the first test. The data was fragmented over disk for nearly 8 months. Steve Harris [EMAIL PROTECTED] wrote: How does TSM access the data on file volumes? Does it keep an offset of the start of every file or aggregate?

Re: D2D on AIX
Hi Comparing these types of numbers are abit unfair. We have customers running 9840 and LTO-2. They have alot higher throughput than 8-12GB/hour over a GB nic. For example, we have a customer running Netware. The TSM server is an AIX server(pSeries 615) connected to a 3584-L32 library with 3 LTO-2 drives. The Netware server has about 200GB of data. The AIX server has three 100Mbs nic, bundled togheter in an Etherchannel interface(theoretic speed is 300Mbs or 30MB/s). The netware server is connected through 100Mbs ethernet(single adapter). The server have a restore time of about 5½ hours which means we have an hourly throughput of almost 40GB/hour. Average networkspeed is 11MB/s. The Netware server utilizes multi-session restore, which means it can mount multiple volumes at once for restores. We have another customer running a pSeries 650 clustrer. The cluster is attached to a 3584-L32 library with 9 LTO-2 drives. The pSeries server is equipped with an Etherchannel interface which consists of 2 GB nics. During testing of a restore scenario on one of their Lotus Domino servers(300GB of data), they reached about 50MB/s restoring directly from tape. In this case, we didnt utilize multi-session restore, which meant that the single LTO-2 drive could deliver 180GB/hour. Today, the new tape technologies can easily outrun disks. To match LTO-2 drives against disks, you'll ned large, fiber-attached disk subsystems, with no other load than the TSM server load. Internal SCSI-disks can never outrun fiber-attached LTO-2 drives. The LTO-2 drive has a native speed of 35MB/s, compressed around 50-70MB/s depending on the type of data. They also have dynamic speed, which means you dont get the back-hitch as long as you keep writing data with at least 15MB/s. We've seen theese drives push up to 90MB/s on database backups and restores. During the testing phase of the implementation, we had up to 380MB/s from the disks(two mirrored FAStT900 connected through 4 FC HBA:s with 34 15K 36.4GB fiber disks per FAStT system) and almost 650MB/s from the drives(9 LTO-2 drives connected through 4 FC HBA:s). The speed of the drives is all about design. If you attach a large number of drives to a single FC HBA, you'll easily get back-hitch. With the LTO-2 drives, a fair number of drives/adapter is around 3-4 / adapter. Designing disk to match the tape drives is all about cost. S-ATA drives can never outrun LTO-2 drives, at least not when it comes to large files or database backups and restores. Designing FC disks to match the drives will mean the cost is 10 times the cost of the tape drives. This is all my opinion, and I'm sure that there are others out there that dont agree.

How much will it increase the size of the db. Ours is already 90G at 70% utilized. It's always a good idea to keep the DB size in the back of your mind; but my take is that you probably don't need to think too hard about adding something with size 'thousands' to it. I started to feel that I had too many volumes at one point when I had remote server volumes at 2G, and I had several hundred thousands of them. To help yourself feel more comfortable with this, I suggest that you take a 'Q occ' of a few nodes you consider small, moderate, and large. Count the total number of objects, and compare. I find that even my small nodes have hundreds of thousands of objects. I don't think that the db size per object is particularly close to the size per volume (i.e. the per-volume overhead is probably much much less) , but you can get a taste of the general order of how big is big. - Allen S.

Netware 6.5 upgrade with sans
Hi All, we have upgraded our NetWare servers to 6.5. I will try and make this as clear as I can, we have a Novell cluster with 4 Servers. We have sans attached to them. TSM does not treat them as a cluster. I have installed TSM to each Novell Server and treat them as any normal TSM client. IN the inclexcl.dsm file, I just exclude volumes that reside on the other 3 servers. So if these volumes get pushed over to any other Server within the cluster, they will NOT get backed up. This is the way we want it, due to Novell cluster server and TSM not getting along. Up until this last upgrade of NetWare 6.5 this worked fine, we ran INC backups daily and TSM would see all the Sans volumes assigned to each Server within the cluster.

Re: Upgrade time...
First, going up to TSM 5.2 version will require you to upgrade the Ultrium drivers. Assuming you're using IBM LTO drives. In previous releases the Ultrium drives were controlled via the native driver, but the library was controlled via the ADSMSCSI driver. This changes...the library is now controlled via the native device driver. You need to make sure that you update the driver for the medium changer or TSM won't initialize the library. As with all Windows TSM versions, you must first uninstall before installing the new version. There is a problem with the uninstall for the TSM Server Licenses. The license file DLL is not deleted. This prevents the install from working. Just delete or rename the ADSMLICN.DLL in the C:\Program Files\Tivoli\TSM\server directory after the uninstall. During the install it should(!) recognize your instance and perform the UPGRADE DB. Be patient! Depending on your platform and DB size it could take a while. After the upgrade (and you should probably go to the latest 5.2.3.x release) you will have to re-register your licenses. Upgrades do not preserve this. You can get this from your DRM recovery plan file or Autovault whichever you use. Or just QUERY LICENSE and write it all down. As always before you start this...BACKUP YOUR DATABASE!

Re: D2D on AIX
Tim, we recently ran a bunch of tests on client side compression. In every test the backup ran for 2 to 3 times longer. In some cases this wouldn't be a big deal when you look at the backup alone being incremental and all. However, we also believed that it would also cause the restore to run 2 to 3 times as long to uncompress the data. As a result of these tests and thoughts we decided not to implement client side compression. Uncompress should be much faster and less cpu intensive than compression. In compression you are searching for redundant tokens. In uncompression you are basically performing token substitution.

dsmerror.log configuration
Hi, I am having a little trouble getting the client error log set up correctly for non-administrators on MacOS X servers. I have defined ERRORLOGName in /Library/Preferences/Tivoli Storage Manager/TSM System Preferences file. As it should this definition overrides any environmental export of DSM_LOG by the non-administrator user. However when the dsmerror.log is written by the TSM scheduler the mode on the file is 644 and owned by root:wheel. So when the non-administrator user invokes DSMC they get the infamous 'ANS0110E Unable to open error log file '/path/to/dsmerror.log' for output problem. If leave the path undefined in the dsm.sys the export of DSM_LOG for each user works correctly. But I want all system invoked TSM logs written to the hosts central log path, and any user TSM logs written to the path of there choice. I just can't seem to find a way to do it. Can someone shed some light on this for me? Thanks, Greg

Re: D2D on AIX
These numbers are from STK 9840B drives. I am not talking about a backup and then a restore. I am talking about a daily backup for 8 months and then a restore. File fragemenation dramatically effects your througput over time. Sure we can spin 9840 drives to 100 GB/hr for large files. I have even backed up a file server to 38 GB/hr (throgh 1 GB NIC's) with millions of small files. But over time the speed is effected. It's being unfair it is what it is. For that restore test was it right after a the backup was done? What is the change rate of the data. If it was after 8 months and you still got 40 GB/hr throughput then good deal. I haven't seen that. Daniel Sparrman [EMAIL PROTECTED] wrote: Hi Comparing these types of numbers are abit unfair. We have customers running 9840 and LTO-2. They have alot higher throughput than 8-12GB/hour over a GB nic. For example, we have a customer running Netware. The TSM server is an AIX server(pSeries 615) connected to a 3584-L32 library with 3 LTO-2 drives. The Netware server has about 200GB of data. The AIX server has three 100Mbs nic, bundled togheter in an Etherchannel interface(theoretic speed is 300Mbs or 30MB/s). The netware server is connected through 100Mbs ethernet(single adapter). The server have a restore time of about 5= hours which means we have an hourly throughput of almost 40GB/hour. Average networkspeed is 11MB/s. The Netware server utilizes multi-session restore, which means it can mount multiple volumes at once for restores. We have another customer running a pSeries 650 clustrer. The cluster is attached to a 3584-L32 library with 9 LTO-2 drives. The pSeries server is equipped with an Etherchannel interface which consists of 2 GB nics. During testing of a restore scenario on one of their Lotus Domino servers(300GB of data), they reached about 50MB/s restoring directly from tape. In this case, we didnt utilize multi-session restore, which meant that the single LTO-2 drive could deliver 180GB/hour. Today, the new tape technologies can easily outrun disks. To match LTO-2 drives against disks, you'll ned large, fiber-attached disk subsystems, with no other load than the TSM server load. Internal SCSI-disks can never outrun fiber-attached LTO-2 drives. The LTO-2 drive has a native speed of 35MB/s, compressed around 50-70MB/s depending on the type of data. They also have dynamic speed, which means you dont get the back-hitch as long as you keep writing data with at least 15MB/s. We've seen theese drives push up to 90MB/s on database backups and restores. During the testing phase of the implementation, we had up to 380MB/s from the disks(two mirrored FAStT900 connected through 4 FC HBA:s with 34 15K 36.4GB fiber disks per FAStT system) and almost 650MB/s from the drives(9 LTO-2 drives connected through 4 FC HBA:s). The speed of the drives is all about design. If you attach a large number of drives to a single FC HBA, you'll easily get back-hitch. With the LTO-2 drives, a fair number of drives/adapter is around 3-4 / adapter. Designing disk to match the tape drives is all about cost. S-ATA drives can never outrun LTO-2 drives, at least not when it comes to large files or database backups and restores. Designing FC disks to match the drives will mean the cost is 10 times the cost of the tape drives. This is all my opinion, and I'm sure that there are others out there that dont agree.

Our real world example:We went from around 8 - 12 GB/hr restore off of tape to over 40 GB/hr from the file device classes. Our test was a file server with a little over 300 GB of data. The File server and the TSM server both had 1 GB NIC's. Resource utilization was set to 10 in both cases. The data was fragemented on tape for a little over a year for the first test. The data was fragmented over disk for nearly 8 months. Steve Harris wrote: How does TSM access the data on file volumes? Does it keep an offset of the start of every file or aggregate? If it does, then yes we could skip to the start of each file or aggregate. If it does not, then we need to read through the volume to find the file we are going to restore. Where we have a large number of concurrent restores happening, this could cause performance issues on the array.

Re: dsmerror.log configuration
Greg - It's unusual and unhealthy, from both logical an physical standpoints, to mingle the error logging from all sessions - which may involve simultaneous sessions. In such an error log, you want a clear-cut sequence of operations and consequences reflected. What I would recommend is the creation of a wrapper script for dsmc, named the same or differently, which will put all error logs into a single, all-writable directory, with an error log path spec which appends the username, for uniqueness and singularity. The wrapper script would invoke dsmc with the -ERRORLOGname= option spec.

I suspect your only real alternative is to upgrade to a later version of TSM for Mail (Domino). If management says there is no money for such an upgrade, ask them to compare the cost of a Domino license vs. the worth of the data it would back up.

Re: Client Compression (was D2D on AIX)
I've done some tests in the past (but I have to search for my results ...). Note that these are with 100 Mbs Ethernet. Recent ones: Exchange TDP Exchange DB compressed 50.3 GB - 1:19:30 elapsed time, 10.81 MB/sec (Backup) Exchange DB uncompressed 63.1 GB - 1:36:30 elapsed time, 11.15 MB/sec (Backup) We backup Oracle directly with the b/a client, (No TDP) and always get huge compressions rates (88% compression). This was a multi-session backup test a while ago: (Again on 100 Mbs Ethernet), 9.9GB of source data (compressed to 1.19GB) elapsed time of 152 seconds - this translates to 65 MB/sec which we could not achieve with 100 Mbs Ethernet without the compression. (We tend to max out on CPU on these types of backups). With client compression on backups you have to make sure no files are growing during compression and being resent - this will add time to your backups. We exclude files like .zip etc from compression and also scan the client logs for any files that grow during compression (you can also use compressalways to avoid the resends). I'm going to search for other tests I've done (or do some again) and I'll post those results.

We are evaluating purchasing a large amount of EMC storage, and from everything I can tell, and the customer references we have talked to, they really seem to have their act together. I know there are numerous people on this forum using EMC storage, and I'd appreciate it if a few of you wouldn't mind giving me your opinion of their products and customer service. Anyone having experience with both vendors would really be helpful. Thank you!

storage media inaccessible?
I have 3 tape volumes that I cannot access. Anything that accesses the tape (including Space Reclamation Move Data) get errors (different for each command) that include terminated for volume 99 - storage media inaccessible. I can't figure out why! It doesn't seem to matter whether the volumes are checked into the library or not. (If not, I should get a mount request.) Here is the result from a q vol 9 f=d for one of them. Volume Name: 075D8D Storage Pool Name: WSUTAPEBACKUP Device Class Name: MAGSTARTAPE Estimated Capacity (MB): 10,240.0 Pct Util: 6.3 Volume Status: Filling Access: Read/Write Pct. Reclaimable Space: 35.5 Scratch Volume?: Yes In Error State?: No Number of Writable Sides: 1 Number of Times Mounted: 1 Write Pass Number: 1 Approx. Date Last Written: 09/17/04 02:43:24 Approx. Date Last Read: 09/17/04 01:00:44 Date Became Pending: Number of Write Errors: 0 Number of Read Errors: 0 Volume Location: Last Update by (administrator): REEVES Last Update Date/Time: 09/22/04 15:00:41 Thanks for any ideas.

Re: storage media inaccessible?
Do the tapes show up in your library inventory and are they in the same slots that the q library output shows? -Original Message- From: Nancy Reeves [mailto:[EMAIL PROTECTED] Sent: Wednesday, September 22, 2004 1:45 PM To: [EMAIL PROTECTED] Subject: storage media inaccessible?

Re: storage media inaccessible?
Two of the 2 are not listed in the library inventory. The third is listed in Home Element 61. I'll have to dig up the manual to see which slot that is. I am running an AUDIT LIBR CHECKLABEL=YES right now. I had previously opened the library, so it would check the elements, then run an AUDIT LIBR CHECKLABEL=BARCODE which I was hoping would straighten things out, but didn't.

Re: client schedule failed to start after a win client cluster fa ilback
we have a TSM on a AIX backing up a Windows clustered server, C1 C2. C2 failed and all the services went over to C1. When we fixed C2 we wanted all the resources and services to go back to the way it was. When C2 failed, the shared drive went over to C1 and the client scheduler was running and the drive could be backed up. But when C2 was rebooted and the shared drive was moved back onto the server. The TSM service again to start. We restarted C2 and it still would not start. The shared drive was moved back to C1. TSM scheduler services started successfully on each server giving the ability to back up the entire environment again whilst leaving the cluster balanced. The Event logs did not indicate any specific error relating to the TSM service not starting. Investigation of the Scheduler configuration showed that the security settings and configurations were working correctly and that the TSM client could contact the TSM server successfully. Do you guys have any idea what's wrong. Why we TSM can't backup the shared drive when we fail it back to the original setup?
