Re: Migration should preempt reclamation
Roger Worth mentioning is that the issue is most likely compounded by the migration/reclamation process running during a backup, the performance hit to the TSM server can be severe. You may find a significant reduction in task processing times if you do isolate them. In the past I have temporarily suspended (or limited) reclamation schedules until the initial backups are done and sent the backup data straight to my sequential storage pool bypassing the migration process. -Rick Adamson -Original Message- From: ADSM: Dist Stor Manager [mailto:ADSM-L@VM.MARIST.EDU] On Behalf Of Roger Deschner Sent: Wednesday, February 17, 2016 8:43 PM To: ADSM-L@VM.MARIST.EDU Subject: [ADSM-L] Migration should preempt reclamation I was under the impression that higher priority tasks could preempt lower priority tasks.

Re: Migration should preempt reclamation
A similar script could use MOVE DATA instead of RECLAIM, which has the advantage of checking as each MOVE ends to see if there are drive resources, and intelligently picking a volume, before starting a new MOVE. It also can check an external file for a "pause" or "halt" command, or parse the actlog(s) for ANR1496I messages for similar "commands", and re-read the configuration file so you can affect it without stopping/starting.

Re: Migration should preempt reclamation
We've had this problem as well. Our fix has been to define a maintenance script MANUAL_RECLAIM that reclaims each storage pool in parallel, but with a duration of 3 hours: PARALLEL RECL STG DESPOT-OFFSITE-LTO TH=60 DU=180 W=Y ... SERIAL An admin schedule will run the script every four hours, except on days we do offsite media checkouts, so that other processes have a shot at grabbing a tape drive. This actually solved an additional problem for us: that of having copy volumes in drives as MOVE DRMEDIA is running.

Re: reclamation
TSM regards the tape as "FULL" once it reaches full status, and until data is completed expired, deleted, or moved off of it. Your reclamation process might have been successful if it had a time limit and reached the end. As others have suggested, try doing a "move data" on that volser and allow it to run until it completes. George Huebschman (George H.)

Re: reclamation
If you have a 'filling volume' you can move data from a tape that needs to be reclaimed (with very little data) hence freeing up a new volume. Of course, you may need to adjust reuse delay to get this back as scratch immediately. --- David Nixon System Programmer II, Enterprise Storage Team Carilion Clinic | 451 Kimball Avenue | Roanoke, VA 24016 540-224-3903 (Work) From: ADSM: Dist Stor Manager [ADSM-L@VM.MARIST.EDU] on behalf of Leonard, Matthew [matthew.leon...@atlasair.com] Sent: Monday, April 14, 2014 12:20 PM To: ADSM-L@VM.MARIST.EDU Subject: Re: [ADSM-L] reclamation Actually doing the Move data command doesn't require any scratch tapes at all.

Re: reclamation
By extension, a logical question: Has Expiration been running? (In a neglected TSM server, it might not be, and getting that going could free a bunch of space.) If Expiration has been running, a recourse is to go looking for obsolete nodes and filespaces to dispose of. If your system has USB, you could conceivably plug in some inexpensive random access media to constitute a temporary storage pool to be able to initiate reclamation. NFS mounting is another way to get space. Richard Sims
Re: reclamation
It can also use filling volumes, but it can't use empty space on full volumes without reclamation. If there are a bunch of almost-empty full volumes, though, even one scratch tape could free up a bunch more scratch volumes using MOVE or RECLAIM.

Re: reclamation
Being that tight, I would suggest you do not look at reclaimation, think move data. That way you can pick a volume, and move it to reclaim the space, then build on that until there is enough space to let reclaimation take over. Reclaim sometimes is not as predictable as you would like. Also consider re-use delay changes. As for a place to write. Either you will need to locate a scratch tape or make one tape scratch.

Tom, When we run into this problem, I'll run the following command after doing a q vol > "c:/vols.txt", opening it into excel and for the tapes that have less than 50% reclaimable I'll run the move data command (see below) MOVE DATA "Volume_name" STGPOOL="Stroage_pool" WAIT=NO RECONSTRUCT=YES Hope this helps!

Re: reclamation
Hmm, this is a tricky situation. The only way you can use delete without reclamation is to free up entire volumes - just deleting files or filespaces are likely to free up partial volumes, but without reclamation there's no way to take advantage of that. Another option would be buying some more scratch tapes, loading those into the library (checking out full volumes if needed), and using those for reclamation.

Re: Space reclamation is ended for volume
Hi Mik, In order to preserve the existing backuped data on the volume, I can suggest you this : 1) Put the tape in readOnly mode: upd vol Volume_Name access=reado 2) Protect current valid datas : Move data Volume_name --> It move all good datas, even the ones that have not been copied yet. --> It flags bad files as damaged 3) audit the tape and fix it : audit vol volume_name fix=yes 4) restore the destroyed datas (when a copy of them exist) : restore vol Volume_Name Hope it helps, Emmanuel -Message d'origine- De : ADSM: Dist Stor Manager [mailto:ADSM-L@VM.MARIST.EDU] De la part de mik Envoyé : jeudi 12 décembre 2013 11:10 À : ADSM-L@VM.MARIST.EDU Objet : [ADSM-L] Space reclamation is ended for volume Hi Eric van Loon and thanks for the reply, I have already try the audit volume and audit volume fix=yes and no error on th file, i don"t understand.

Re: Space reclamation is ended for volume
Hi Mickael! Audit the volume like this: Audit vol S:\TSM_FILE_DEVCLASS\16AA.BFS This will show you the files which are corrupted on the volume. It could be that the volume was corrupted after a successful backup stgpool, so first try a restore: Restore volume S:\TSM_FILE_DEVCLASS\16AA.BFS If the restore is successful the volume should be empty afterwards, if not you will have to perform an audit again but with the fix=yes: Upd vol S:\TSM_FILE_DEVCLASS\16AA.BFS access=readonly Audit vol S:\TSM_FILE_DEVCLASS\16AA.BFS fix=yes Bear in mind that the corrupted files will be deleted from TSM. If these files are Backup/archive client files it's not a very big issue: they will be backed up again during the next backup cycle. Are the files part of a TDP backup then things are different, in that case your whole backup series is corrupted and you will have to schedule a new full backup for that TDP client a.s.a.p.

Check a recent APAR https://www-304.ibm.com/support/entdocview.wss?uid=swg1IC95938&myns=apar&mynp=DOCTYPEcomponent&mync=E for a similar problem.

Re: Reclamation of Virtual Tapes
That may be the issue. The DD880 does not reach peak performance until it has 5 shelves, or 80 total disks. Until that point it has more CPU than disk IO.

Re: Reclamation of Virtual Tapes
My experience with DataDomain (VTL option) is different than Jim described. I have 2 TSM servers (P6 hardware) using 1 DD. We have not seen a performance difference no matter what is running beyond what you would expect as the 12Gb (ISLs) of available bandwidth is used up. Perhaps the specific DD and the number of disks it has should also be included in the discussion. Mine is an DD880 with 84 active disks.

Re: Reclamation of Virtual Tapes
I noticed a serious performance drop when our backup primary tapes to copypool runs at night (VTL Quantum DXi8500 to TS1140 tapes). The throughput of backups to VTL drops when the DXi "rehydrates" the deduplicated/compressed virtual tapes. I can imagine the reclamation process does the same thing.

File integrity check during reclamation?
Has anyone seen any documentation from Tivoli, stating that a file integrity check (or CRC check) is performed during the reclamation process? (In an LTO-4 pool in this case, on TSM 5.5 on AIX.)

Re: reclamation question
On occasion I have deleted a vol from a copypool when the percent utilized number dropped to a couple of percent. In our setup we have three identical data pools so we should ok but it's not something I do very often. I have watched the offsite reclamation process sit there for most of an hour or more just thinking about it before it would load a tape and get to work. I'm kinda ok with that because of all the work going on under the hood.

Ang: reclamation question
As the previous 2 mentioned, if the tape is available, TSM will use it. If it's
offsite, TSM will try to collect the data from primary volumes. So your issue
is that the copypool tapes are actually available. It's kinda weird you get
them reclaimed though, they should have been moved offsite long before reclaim
is needed. Are you storing large database/mail/other application backups on
them which expire regularly?

We have three storage pools, the primary pool is a devtype FILE and the two copy pools are devtype LTO3. The offsite copy pools gets transferred offsite via DRM. Whenever I run a reclamation on the offsite copy pool the system grabs a scratch tape and then copies files from the primary pool and starts filling up tapes. I'm perfectly happy with that process. I have an issue when I do the reclamation of onsite tapes. It loads up a tape (might be scratch) and then another tape to copy the data from. It ends up doing a tape to tape copy. In a way it uses twice as many tape mounts as an offsite reclamation. And since I only have 6 drives it kinda cramps up my options sometimes. Is there a way to do a reclamation of the onsite copy pool and have it pull data from the primary pool instead of doing a tape to tape copy? I mean it can do it for the offsite pool, why not the onsite as well?

Re: reclamation no longer working
I had the same problem and offsitereclaimlimit=20 (or whatever you want to limit it to) worked for me. In my particular situation my server is 5.4.1.0 (I know, very old!) running on AIX 5.3 (5300-09-01-0847). I have a few (less than 5-10) tapes at a 99% reclaimable level in my offsite COPYPOOL01 tapes, but about 500 tapes that are 98% reclaimable. If I do NOT specify a offsitereclaimlimit number it seems to process tapes to reclaim at about 3 tapes per minute. So for 500 tapes it just sits there for about 3 HOURS before it even starts mounting tapes to start the reclamation. I stumbled onto how useful this particular option was about 3 or 4 months ago thanks to this forum, before that I didn't have a clue what it was supposed to be used for. Limiting it to 20 tapes lets it actually start mounting tapes and moving files in about 6 or 7 minutes. I also noted that in a recent posting in this forum, IBM has fixed the order in which tapes are reclaimed, and if you specify something like 90%, it will start with 99% first, then 98%, 97%, and so on until it finishes or runs out of time. This solves my biggest gripe about reclamation that I have had. I have two new servers that will soon be in production, and they are running the 6.2 TSM, so they should reclaim much faster.

In most of the cases I've examined, it is because the now-onsite tape begins with a segmented Physical File which is continued from a tape which is not available (e.g., marked Offsite), where the reclamation then runs with primary storage pool tapes only as it starts by copying the entirety of that first Physical File - which takes more time. A few cases have remained mysterious. Richard Simsat Boston University

Bringing offsite tapes back and reclaiming them onsite is much faster; but, of course, then that data is not offsite. Richard Sims http://people.bu.edu/rbs/ Richard, from time to time I've had to do this. After checking in the tapes and updating them to r/o or r/w TSM doesn't always use them for the source on a 'move data'. Sometimes it does, sometimes it doesn't. It acts as if the tapes are not in the library even after I've verified them. Would you know any reason why? TSM 5.5.3 - LTO4 library.

In my experience, that is a manifestation of the TSM server running through the database (you should see a lot of disk activity there) compiling a list of all the onsite tapes necessary to represent all the files on the offsite tape which is to be reclaimed.

I checked the pct_utilized numbers and saw that the tapes varied from 99% down to just 5-6% utilized. When I manually run the reclamation process and then do q process I see that I have the right number of processes that start up. But the status never changes from showing zero moved files. It just sits there like it's thinking about it but never mounts anything. It runs for the duration I set then closes out. I also moved the duration back and forth from a few minutes to a couple of hours and that didn't help either. I've run the threshold up and down from a few percentage points up to 80-90% hoping something would change but no difference. I have plenty of scratch tapes and mount points. I have another onsite tapepool that is identical. But it will do reclamation just fine. Just for the heck of it I created a new offsite tapepool using essentially the same settings as the old pool and it's appears to run reclamations just fine. Nothing has been changed in the settings for the offsite copypool and the onsite copypool either.

Re: Collocation Groups Reclamation and Restore
Hello Colleagues, I have found all answer to my questions. And from my point of view are very interesting and I would like to share with all TSMpeople. 1.- When one volume is reclaimed in this pool ( Pool with CG). How TSM does the reclamation? moving files from one node from Volume to Scratch one or TSM moves all nodes in the CG at the same time without distinction ? it moves it from all nodes 2.- When TSM restores files from these tapes. Does it restore all files in a sequential way ?. I mean TSM is reading the tape from the beginning and if it finds files to belong to this TSM Client from different directories it restores independently of the directory which this files belong or TSM server prepares a list of file and it is looking one per one in the tape... or Which is the procedure ? - it restores sequentially - so that it minimizes the tape movement. 3.- In case of migration, if we don't have CG TSM migrates files per node. What happens if we have CG, it is per node or per CG ? per CG 4.- In case we have a lanfree backup with 4 parallel sessions , is CG suitable for this TSM Clients ? sure, the better question is do they have enough data being written to keep the tapes streaming, versus the advantages of writing to disk. 5.- Last question, in order to restore the client node. Are there differences between these procedure and multiplexing competitors ones ? ... --- yes. for multiplexing, they have to rebuild each individual file. THis causes lots of tape positioning, and additional process to rebuild the files. Multiplexing has a very large NEGATIVE impact on restore times.

It doesn't tries to restore in alphabetical order for example. The restore thread will read all the relevant files from a particular tape regardless of their alphabetical order or backup dates. Then move to next tape. The goal is to minimize the amount of tape mounts.

Collocation Groups Reclamation and Restore
Hi TSMers, I have some questions about Collocation Groups Reclamation and restore. First, my environment I have a Tape STGpool with 3 Collocation Groups and 10 nodes per Group. 1.- When one volume is reclaimed in this pool. How TSM does the reclamation? moving files from one node from Volume to Scratch one or TSM moves all nodes in the CG at the same time without distinction ? 2.- When TSM restores files from these tapes. Does it restore all files in a sequential way ?. I mean TSM is reading the tape from the beginning and if it finds files to belong to this TSM Client from different directories it restores independently of the directory which this files belong or TSM server prepares a list of file and it is looking one per one in the tape... or Which is the procedure ? 3.- In case of migration, if we don't have CG TSM migrates files per node. What happens if we have CG ? 4.- In case we have a lanfree backup with 4 parallel sessions , is CG suitable for this TSM Clients ? 5.- Last question, in order to restore the client node. Are there differences between these procedure and multiplexing competitors ones ? ... Thanks, Fran
Reclamation macro or script

Re: Reclamation for offsite storage pools
You might be running into what I've seen if you are performing your reclamation via RECLaim STGpool. If you have many very low utilized tapes and you do not use an OFFSITERECLAIMLIMIT then it is possible that the reclamation process will only yield another tape going off site and none coming back. Say you have 1.5 TB tapes (est capacity) and your off site copy pool is mainly volumes that are 5-10% utilized (which works out to be between 75-150 GB's) and your drives can read/write at 200 GB/hr so to fill one new tape it will take 7-8 hours and require the clearing of 10-20 ~offsite~ tapes. TSM will look at ALL tapes that meet the threshold setting so if you have 30 off site tapes at 10% or less... unless you do something such as use an OFFSITERECLAIMLIMIT of 5, TSM will start reclamation across all 30 of those tapes and unless you allow it to run for at least 12 hours, you are unlikely to get back very many if any tapes.

Re: Reclamation for offsite storage pools
Hi George, Will it restart if there are more than 4 tapes that meet the criteria of being at least 98% empty? (Just following my example.) Or will it just stop after it does 4 and not start another process with 4 more volumes to reclaim? (That is if there are 4 more that meet the 98%+ free space requirement.) Just let me know.

No. That reclaim process would process a maximum of tapes (if there are that many 98%+ empty) and then stop. You would have to repeat the command to do the next four.

Re: Reclamation for offsite storage pools
Ah, I've been through this many times. As someone mentioned, stepping down by setting the threshhold to 99, then 98 and so on over time will work well. This is assuming you can fit all of your primary pool volumes into the tape library. You can use the following select command to keep track of how many tapes you have at each level to judge when it's time to lower the threshold. (I think this is one of the example select statements in the HELP SELECT page. (replace TAPE_C2 with your stgpool_name select count(*) from volumes where stgpool_name='TAPE_C2' and status!='EMPTY' and pct_utilized <50 I went through a major catch-up once where this wasn't possible because the average primary pool volume was also mostly .05-.1 pct utilized. In that case, just sort the volume list by pct-utilized and recall and systematically run move-data on each volume starting from the least utilized. (a unix shell loop is great for this) I consolidated 8000 tapes down to 200 on that project!

Re: Reclamation for offsite storage pools
I totally agree on this. At one time, we had such a time with offsite reclamation, we would set it to 99, then have a script run checking for reclamation processes, and bump the number down by 1 if there were none. A hack, to be sure, but we eventually caught up. On Wed, Jan 27, 2010 at 8:31 AM, David E Ehresman wrote: > What level are you setting for reclamation.

Re: Reclamation for offsite storage pools
Having been in this shape before I can tell you what I've done in the past. First, A very valid option at this point is to delete the offsite volumes that are very underutilized and just let the normal storage pool backup routine recreate the data. example I would start by deleting volumes that are 5% used or less (maybe 10 - 20 a day). Then, start catching up by setting the reclaim threshold pretty high (depending on the number of tapes in the higher percentages) and setting a limit on the number of tapes reclaim deals with each night. Fore example, set the reclaim threshold to 90% (and if there are a large number of those limit it to say, 15 or 20). Also, if you have the drives available set the pool to run 2 reclaim processes. Make sure not to delete the onsite copy or you just lose the data. It takes a while but if you stay with it eventually you'll start getting lots of tapes back.

That is what reclamation does for you without you specifying individual volumes. You use a reclamation threshold in a command or a storage pool threshold and TSM picks the volumes. With a MOVE DATA on a copy pool volume, TSM just grabs the data from the primary pool. You can let reclamations/move data/move nodedata run through housekeeping if needed. Ordinarily it isn't the best thing to do, but it shouldn't break anything. -Original Message- From: ADSM: Dist Stor Manager [mailto:ads...@vm.marist.edu] On Behalf Of Moyer, Joni M Sent: Wednesday, January 27, 2010 8:54 AM To: ADSM-L@VM.MARIST.EDU Subject: [ADSM-L] Reclamation for offsite storage pools Hello everyone, For several years I had not been able to run reclamation on one of my tsm servers due to the lack of physical tape drives to accomplish the task.

Re: Reclamation for offsite storage pools
Hi George, When you get behind with reclamation, you end up with many volumes with low util/high reclaim values. TSM trys to minimize tape mounts by reclaiming offsite data from your onsite tapes without too many remounts, which can pull data related to several/(or many) offsite volumes. You can force a more expeditious reclaim by specifying a high reclaim percent (95% or so) and setting OFFSITERECLAIMLIMIT to a small number (1 or 2). This will optimize getting volumes back at the expense of (probably) more local tape mounts. If you want to get a specific tape cleared, do a MOVE DATA. If you have the media, you could create a new pool and delete the old copy pool once the new one has been populated.

I guess I'm trying to come up with a more efficient method of getting caught up as reclamation just isn't accomplishing what I hope it would.

That is what reclamation does for you without you specifying individual volumes. You use a reclamation threshold in a command or a storage pool threshold and TSM picks the volumes. With a MOVE DATA on a copy pool volume, TSM just grabs the data from the primary pool. You can let reclamations/move data/move nodedata run through housekeeping if needed. Ordinarily it isn't the best thing to do, but it shouldn't break anything. -Original Message- From: ADSM: Dist Stor Manager [mailto:ads...@vm.marist.edu] On Behalf Of Moyer, Joni M Sent: Wednesday, January 27, 2010 8:54 AM To: ADSM-L@VM.MARIST.EDU Subject: [ADSM-L] Reclamation for offsite storage pools Hello everyone, For several years I had not been able to run reclamation on one of my tsm servers due to the lack of physical tape drives to accomplish the task. I am in the process of trying to get caught up, but it seems that I just never do. Most of my issue is with the copy storage pool volumes which are very under-utilized. It seems like reclamation, even if I start multiple reclamation threads, is taking quite a long time. Is there some other way for me to get the data onto new media without doing reclamation? Can I do a move data from 1 copy storage pool volume to the another volume within the same copy storage pool? I know that this would mean bringing the tapes back from the vault, but it is just not progressing as I would like with the reclamation processes. Any suggestions are greatly appreciated as I would like to get this back under control. Thank you in advance!

Re: Reclamation for offsite storage pools
Joni, Yes it does. I was just pointing out that with the move data command, you specify the volumes, whereas with reclamation, TSM does the prework of selecting volumes. This can be time consuming, as David points out. Geo IMPORTANT: E-mail sent through the Internet is not secure.
