HELP NEEDED ASAP!!
One of oour main windows 2003 server crahsed today and the san disk it turs out is corrupted and we need to restore 2TB of user files to a new server. The users cannot login to their workstations because this server is used in our login process and each user maps a home directory to a share on that server when they login. I am in the process of creating a backupset so the restore can go quickly but our management needs the users to at least be able to login even if there data is not restored yet. So if I start a restore will TSM recreate all the folders with permissions first then start putting the data back last? If we can get the folder structure back first we can at least let people login. Does anyone know if TSM will put the folder structure back first with permissions? Thanks
Re: Will TSM ever support BMR for windows systems?
I don't know what method you are for a BMR recovery but I have used what most people in this list suggest. I simply reinstall the OS (from and install cd or image using something like altiris or nlite) then install the TSM client then restore C: drive files and then registry and reboot. Which works MOST of the Time but I need something that works ALL THE TIME. I have a windows server now that this process does not work for and I am getting lots of flak for it and now they are considering moving to another software that does support BMR for windows systems. I am in constant arguments with management and they want to know, why can't tivoli do what altiris does? Simply restore an image from a backup of the os from boot to the same exact same server without having to reinstall the os. Dissimilar hardware isn't even a concern for them because they are will to require same hardware in their DR plan. Besides I don't see why TSM can perform a snapshot image backup of the local system drive of a windows server but you can't restore from it and actually use it to boot another system. Networker claims they have BMR for windows system built into their product so why doesn't Tivoli. -Original Message- From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED] On Behalf Of Mark Stapleton Sent: Wednesday, December 06, 2006 10:02 AM To: ADSM-L@VM.MARIST.EDU Subject: Re: Will TSM ever support BMR for windows systems?

I've talked about this on this list more than a few times, but I'll repeat it for our new folks: ** You can use TSM to perform bare-metal restores of Windows machines, to similar and to dissimilar hardware. ** It is a pretty straight-forward process for identical hardware, and dissimilar hardware merely requires a little file-shuffling during the rebuild process. I've performed BMR using nothing but a modified Windows boot CD, nLite http://www.nliteos.com/ (donate to those folks--their code's great!) and a copy of the TSM client code. I just don't think it could be that difficult for Tivoli to come up with a boot cd like they use for ServerGuide that is TSM aware and capable of hardware detection. It's not Tivoli's go to create CDs to facilitate alternate-boot disks for various OSs. IBM already has that process down cold for AIX. Similarly, Sun for Solaris and HP for HP-UX. For Windows, Microsoft developed WinPE, and BartPE is out there for Windows as well. It can be done, folks.

Re: Survey Question for Virtual Tape Users: What Vendors are you using for Virtual Tape?
I have a Sepaton VTL and it has helped us tremendously to meet our requirements. Although the VTL did help reduce our backup window by over 70% and we have sustained backup speeds of 150MB/s and I have seen them has high has 300MB/s. You are going to need to reconfigure the way your clients backup for example you may need to reconfigure your db2 client for better disk read performance and send data using multiple TSM sessions most of the time the client is the bottle neck. Then you should start looking at your TSM server, we had to implement aggregate multiple gig network cards just to handle the client throughput. You may also need to implement multiple san cards to your disk storage or vtl to get the required throughput. In my experience with vtl's they do write much faster than regular disk pools and tape drives. We use TS1120 drives and I was not able to get better throughput to my tape drives than I am getting to the VTL. And the tape drives are supposed to be faster.

I concur with Kelly's evaluation. Where VTL's really shine: -On restores of multiple files (like restoring a large directory of small files), no tape mounts are required, even if data is not collocated -Since you don't need to collocate, migration and on-site reclamation are much faster. -Reclamation of offsite tapes is MUCH faster, as the input tape mounts are eliminated But most VTL's on the market are made with SATA disk, which are at the low end of disk performance. Depending on the vendor, model, configuration, and your client hardware, backup restores from VTL's of a SINGLE LARGE FILE file may not be any faster than (fast) tape. And then there is the question of how fast your SERVER can push data (most of my customers don't have servers yet that are capable of pushing LTO3 drives at full speed!) So you need to REALLY figure out where your bottleneck is before you decide how to fix it. -If what is causing you to run slowly is MOUNT times, you need a VTL. -If what is causing you to run too slow is WRITE time, and your write speed/sec is already up to LTO2 speed (30-35MB/sec), it may be more cost-effective to drop in LTO3 drives, which are more than twice as fast. (75-80MB/sec for IBM LTO3). -if what is causing you to run too slow is WRITE time, and your write speed/sec is less than 30-35MB/sec, it isn't the LTO tape that's causing your problem - your bottleneck is somewhere else! (like your server DB, your network, your diskpool, the client etc.). That being said, implementing a VTL is very easy and has many benefits. However, if you decide to go with a VTL, MAKE SURE you get a commitment from the vendor of how many MB/sec SUSTAINED throughput they support, so you have an idea just how fast you can push AND /pull 1 TB of data IN A SINGLE LARGE FILE.

Based on your config I'm guessing you're having trouble completing the backup stg operations due to the fact that you get a single large process running to a single tape drive (or tape to tape) and that's taking too long. I would suggest using the copystg parameter on the primary tape pool and have that large database go directly to the primary and copy pool tapes simultaneously. That will eliminate the need to do the backup stg tapepool copypool operation during daily processing. I would also backup stg diskpool copypool before I migrate.

Re: VTL Sepaton vs SUN/STK(FalconStor)
I spoke with sepaton, emc, copan, IBM, and sun over the course of 4 months starting in Jan. of 2006. I choose to go with sepaton for a number of reasons: they scale by size and PERFORMANCE (which is something none of the others could match), price was good and maint. was reasonable, roadmap for future products was excellent and wasn't dependent on what falconstor was doing, and I liked the way they approached doing large block I/0. All the vendors accept sepaton just ran falconstor on their hardware and I didn't like that approach. Copan I believe didn't use falconstor but their unit was so heavy that it couldn't sit on a raised floor in the datacenter if it was full. Sepaton was the only pure VTL vendor meaning that VTLs were all they focused on. I have not had any problems since the installation 3-4 months ago and like I tell others the sepaton vtl has literally given my life back meaning that I am not checking TSM every few hours daily even while on vacation anymore. I don't want to sound like an ad campaign for sepaton but in my opinion their leading the pack and their support team is excellent as well.

Can 64bit TSM client on 64 bit os overcome backing up large filesytems??
I am having problems backing up a large filesystem on a win2003k server. The backup is failing because its running out of memory which IBM says is because of the 32bit os limitation. Tried journaling but the server is very busy and continuously gets buffer overflows and the journal fails and I have tried tuning it as well but it still fails. I have not tried the image snapshot backup but I don't trust doing it on a 1 TB windows filesystem. So I was thinking of upgrading the server to win2003k 64bit and loading the tsm 64bit client to backup the server to overcome the 32 bit limitations. Do any of you guys see a problem with that or will I still have the same problems as before? **EMAIL DISCLAIMER*** This email and any files transmitted with it may be confidential and are intended solely for the use of the individual or entity to whom they are addressed.

Re: VTS or san disk storage
Your situation sounds even worse than mine. When I lose a lun I only lose that particular lun. Other systems and luns on the controller are still functional. Although in order to get that lun back I must shutdown every system connected to the controller then reboot the controller and the lun comes back. I was told later by HP that the controller can only handle 6-9 I/O requests per lun per second. I am looking for other storage units that can handle more requests than that. I noticed that I don't have this problem with IBM storage at least the ssa's we don't have any IBM san storage. -Original Message- From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED] On Behalf Of Tab Trepagnier Sent: Tuesday, November 29, 2005 5:20 PM To: ADSM-L@VM.MARIST.EDU Subject: Re: VTS or san disk storage Richard, I share your pain. We have an EMC Clariion CX500 SAN. We have found that AIX in general, and TSM in particular, can just hose the sucker. Your observations about write cache were echoed by EMC. We had to turn off write-cache on our TSM disk pool LUNs because the SAN storage processors couldn't keep up with the incoming data rate and manage the cache at the same time. In our case, it manifested itself as a total network freeze! Once our TSM server - a 2-way 6H1 - started writing to our five-disk RAID-3 LUNs, the I/O would hog the SAN so that no other servers - like our domain controllers - would get any disk access. Disk queue length on the DCs went to 50+. With the DCs locked out of the disks, they couldn't process DNS lookups, logins, etc. so our Active Directory LAN just hung. The odd thing is that all our TSM disks are in their own disk pod; the only thing shared between TSM and the remainder of the servers was the internal fiber loops and the SPs. There was no disk contention between TSM and anything else. We duplicated the problem when creating disk volumes in TSM. We duplicated the problem when our Windows-based Domino servers backed up to SAN-based disk pools. We duplicated the problem when we copied a large database from one Oracle server to another; both with data volumes on the SAN. All of this occurred at data rates of about 50-55 MB/s. We use RAID-3 for TSM disk pools and RAID-5 for everything else. With the write cache turned off we get more like 12 MB/s streaming to a five-disk RAID-3 array. So with TSM using the SAN as a major storage resource, we've had to give up performance and reliability. On the upside, at least it's only three times as expensive as tape!

The explanation we were given was that they had chosen to do this for application performance reasons; it was apparently quicker that using a DBMS. This decision, although it made random access of data quicker, had horrible implications for backup as the log data and reports accumulated over time; recovery was even worse. Aggravating the situation was the insistence by the application owner that ALL historical log data absolutely had to be maintained in this inside-out database format. Just getting a count of files and directories on this drive (via selecting Properties from the context menu) took something on the order of 9 hours to complete. The volume of data, in GB, was really not that large - something on the order of 100 GB. All of their problems managing the data stemmed entirely from the large number of files and directories. When the time came to replace the server hardware and upgrade the application, they had extreme difficulty migrating the historical data from the old server to the new. They did finally succeeded in copying the data from the old server to the new, but it took days and days of around-the-clock network traffic to complete.

At another customer, we and the customer's sysadmins were bedeviled by a weblog analysis application (which shall remain nameless) that chose to store its data on the filesystem, using the date of the log data as a directory under which the data was stored (as well as the associated reports, I believe). The explanation we were given was that they had chosen to do this for application performance reasons; it was apparently quicker that using a DBMS. This decision, although it made random access of data quicker, had horrible implications for backup as the log data and reports accumulated over time; recovery was even worse. Aggravating the situation was the insistence by the application owner that ALL historical log data absolutely had to be maintained in this inside-out database format. Just getting a count of files and directories on this drive (via selecting Properties from the context menu) took something on the order of 9 hours to complete. The volume of data, in GB, was really not that large - something on the order of 100 GB. All of their problems managing the data stemmed entirely from the large number of files and directories. When the time came to replace the server hardware and upgrade the application, they had extreme difficulty migrating the historical data from the old server to the new. They did finally succeeded in copying the data from the old server to the new, but it took days and days of around-the-clock network traffic to complete.

Re: 15,000,000 + files on one directory backup
Yes, but the long backup time is because of the time it takes the TSM client to query the TSM database for backup file candidates and not due to the actual movement of files from the client to the TSM server. So how pulling from 10 separate drives increase the query speed. For instance it takes hours and GB of memory on my client for the client to query the TSM server for file info for 15 million files even though the actual backup will end up being 11,000 files consisting of 300mb. And the backup take over 17+ hours to complete. This is running from a GigE connection with my client with 4 cpus and 6GB of memory although it is Win2k. -Original Message- From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED] On Behalf Of Stapleton, Mark Sent: Thursday, June 16, 2005 12:53 PM To: ADSM-L@VM.MARIST.EDU Subject: Re: 15,000,000 + files on one directory backup No, because you're pulling data off of 10 separate physical drives.

Slow backup performance

With the current 5.2 tsm client loaded it is taking about 25+ hours to backup. Is there anyway to speed this up?

If you use Jumbo Frames at the client, tsm server and switches. You will see a higher through put with a lot less cpu utilization.

Either it cann't read from its disk fast enough to support gig speeds or the client cpu cann't process the data fast enough.

If the client is a production server then not only is it processing the backup, it has to do whatever it was built for as well. So you have two applications battling for resources at the client. The tsm server only has one thing going on an thats backups. If you change resource utilization you could get some jump in throughput but at the same time the other app running on that client will suffer. Is it really worth it? Maybe in your environment but thats your call. -Original Message- From: William Rosette [mailto:[EMAIL PROTECTED]] Sent: Monday, December 30, 2002 9:24 AM To: [EMAIL PROTECTED] Subject: Re: Gigabit Ethernet speed What about upping the RESOURCEUTILIZATION?

Re: VMS Client Performance
You know I had a problem similar to this. We were doing a large restore of a system disk about 50,000 files 1.6Gb. It took about 20 minutes to build the file list. When it started restoring it restored 1Gb fast and then the session hung for 45minutes. So I killed the session from TSM and it reconnected and started moving files again from where it left off but after about 30Mb more it hung again. So I killed the session from TSM again and it reconnected and did another 10Mb and hung again. This happened about 5 times before it completed. I don't understand why it would hang. It wasn't waiting for a tape mount, it would just sit there. It took us 2hours to restore 1.6GB. Richard -Original Message- From: Kelly Lipp [mailto:[EMAIL PROTECTED]] Sent: Thursday, December 20, 2001 2:14 PM To: [EMAIL PROTECTED] Subject: Re: VMS Client Performance Paul, Kelly - If the FTP times are similar, then another possible cause of this is that the output disk has file highwater marking turned on (this is the default). Or, the output disk is very fragmented and nearly full. For a restore of such a large file, either of these issues can be a significant. Another item to check is whether the file is marked for contiguous restore or contiguous best try (ABC SHOW BACKUP file /FULL will show this). If so, the restore can take much longer than otherwise unless the disk has very large chunks of free space. I would expect the problem to be either some network issue (one should check the OpenVMS LAN device via LANCP SHOW DEV/COUNTER and possibly LANCP SHOW DEV/CHAR) or the above-mentioned disk issues. To change the file highwater marking: $ set volume/nohighwater device: Note that you probably want to reinstate file high water marking after the restore. It is part of OpenVMS file security and helps prevent disk scavenging. To check the fragmentation state of the disk: 1. Install Compaq's DFO from the condist or the DFU utility from the OpenVMS freeware CD. 2. Run DFO's file analysis command, which does not require a license. Or, run the DFU disk analysis command(s). Finally, it would be interesting to see the summary produced by ABC for the restore. The summary data rate would give us an idea about whether the bottleneck is network (data rate slow) or disk (data rate fast, but wall-clock time long). In the disk case, the problem will be in file allocation not the data transfer portion. For degenerate cases, file allocation can take an enormously long time. So, there are two possible bottlenecks: Network or Disk. Oh, almost forgot. Typically (unless drastically changed) the TCPwindowsize and TCPbuff settings have only marginal affect. I recommend leaving them alone. This is especially true because we see reasonable performance during the backup. Regards, Steve Kelly J. Lipp Storage Solutions Specialists, Inc.

Is data going to go through four etherchannels because you start four sessions? If so, your implementation might work. Make sure not to start more sessions than your max mount point for your node on the TSM server. I hope you are aware that Oracle7 is not supported by both Oralce and Tivoli anymore. regards, Thiha I'm interested in determining if etherchannel and EBU/TDP for Oracle, might be effective in reducing backup times.

Proposal is to speed up backups by using 4 ethernet adapters in both the client and the server and use Etherchannel. 4 parallel sessions would be set in the EBU script. A much larger database will be implemented shortly and etherchannel looks attractive, providing TDP for Oracle will use 4 concurrent sessions, which I think it should.

Re: Cache Hit Pct.
My Buffpoolsize is set to 65536 and SelfTunebufpoolsize is set to yes as well. So I would assume it would tune itself to the right value.

Richard, Your cache hit percentage is too low at 95.6 percent and as you have pointed out, should be around 98 percent of above. To change the percentage of your cache hits, increase by doubling, the size of your BUFPOOL parameter in your dsmserv.opt file on your TSM server: entry from my dsmserv.opt file: BUFPOOLSIZE 16384 You should then wait a day or two and see what it rises to. Each time, you will need to reset the associated statistics with the reset bufpool.

Re: full backup question.
Either start using collocation on the tape storage pool, which will help in the future with restore speeds. But for now I would say create a backup set for the machine you are going to restore.

Re: HSM for NT
Well it does make since if you have mutiple gigs of space being taken up on your servers because of data that hasn't been accessed in years. Its better to migrate that data to cheaper media. Tape is still cheaper than disk depending on who you are getting it from. Also the labor involved in extending disk drive resources are extensive across 100 home directory servers and growing. You might say why don't you get a SAN but if that SAN is down for any reason my entired network is down. HSM is a needed product and it should work on highly used servers or infrequently accessed servers as well. -Original Message- From: Mark Stapleton [mailto:[EMAIL PROTECTED]] Sent: Friday, June 15, 2001 10:49 PM To: [EMAIL PROTECTED] Subject: Re: HSM for NT From: Dearman, Richard [mailto:[EMAIL PROTECTED]] Is anyone using the HSM for NT product that intergrates with TSM called OTG Diskextender?

Re: 500GB Backup
When you say stripe across 5-6 disks are ou saying a RAID5 set. Also, I thought if you set compression at the client level, the data will not compress when it gets migrated to tape. Also, what do you mean by at the block level. Should you use JFS or raw filesystems for your ADSM volumes. -Original Message- From: Jeff Bach [mailto:[EMAIL PROTECTED]] Sent: Monday, April 30, 2001 10:52 AM To: [EMAIL PROTECTED] Subject: Re: 500GB Backup Easy to imagine, not take the same amount of money the tape drive cost and buy disk, stripe the disks across 5-6 drives and two controllers at the block level. Dedicate this resource to the one server for the backup period and run the backup. Which is faster now? Also compress on the client so we have an apples and apples comparison.

AIX Question
I'm new to the AIX world so forgive me if the question seems stupid. I installed two nic cards in my H70 running AIX 4.3.3. Both are on different ip subnets. Everytime I set the default gateway for the second nic card it changes the default gateway on the first card to be the same as the second. Am I doing something wrong. It won't let me set two different default gateways for each card.

Re: RAID-5 Vs Mirroring
I seen this situation once before when the parity is unsynced corruption can be caused in the filesystems on the ssa array. And cause the data to become unrecoverable. I saw this happen on an AIX 4.2.1 system before IBM told me that there was nothing that could be done to recover the data and we would have to recover from backup. -Original Message- From: Cook, Dwight E [mailto:[EMAIL PROTECTED]] Sent: Monday, April 23, 2001 10:27 AM To: [EMAIL PROTECTED] Subject: Re: RAID-5 Vs Mirroring Were you using just a single card ?

Therefore another 80 GB space is being used for the second copies. In order to have more usable space for DB, a suggestion has been mooted to go for RAID-5 at the hardware level. IBM's version is that since a second copy MUST be kept , going for RAID 5 shall require more disk space. Now my question is: 1. With the RAID 5 at AIX level, should a second, synchronized copy of DB volumes is required. 2. If I do not keep a second copy and take daily full backup, would it be RISKY. 3. Configuring RAID 5 at this juncture, would anybody see any pitfall ahead. Any comments are welcome!

Advice
Our TSM server is on one ip subnet and a large system I backup every night about 300GB of data nightly is in the same room as the TSM server but on another ip subnet. I would like the data going into TSM from that large system to be switched not routed to TSM. Does anyone know if TSM can listen across multiple nics on different ip subnets if I put another card in the TSM server on the same subnet as the large system I backup nightly.

Re: Advice
I'm not sure I understand, is this what you are saying? My current TSM server has one nic card on 11.0.0.0 subnet. Install another nic card in my TSM server and put it on another ip subnet lets say 10.0.0.10. Then on my client change the dsm.opt to backup to that ip address of 10.0.0.10?

Backup Sets
Currently I do regular TSM ncremental backups of my servers every night. I was wondering is there any reason I should start creating Backup Sets. I still have the ability to restore my server to its last backed up state if it were to fail. Therefore I don't see much reason for doing Backup Sets accept for the ability to restore the downed server from portable media if TSM isn't available. Does anyone have any opinoins on types of backups to do on NT, and AIX systems that will give me the best recoverablity in case of a failure.

MediaW problem
I run my backups at night around 10:30pm. I have around 50 servers doing incrementals concurrently at this time. I noticed that about half are experiencing MEDIAW when I do a "q session". They seem to be waitng to for a tape to load in my library for them to write to but the storage pool that these clients write to first is disk based then when it fills to 90% it should migrate to tape. My question is, if they are suppose to be going to disk storage pool first and it isn't full then why are they waiting for tape. Which is what I am assuming is happening.
