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?

Reclamation question
I've been reading about reclamation and have a question. In the Admin Guide (tsm v5.3) under section Lowering the Reclamation Threshold it describes what happens when the reclamation percent on a stgpool is changed while a reclamation process is running. From what I read, I understand the following . . . . If reclamation if processing a onsite volume, the new threshold is used beginning with the next volume. If reclamation if processing offsite volumes, the new threshold is NOT used used during during the existing reclamation process. It won't be used until the existing process ends and a new one starts. Now, my question . . . . . What does onsite and offsite mean? Does onsite = primary pool, and offsite = copy pool? Does onsite = volume access of rw or ro, and offsite = volumes access of offsite? My guess is the latter: access = offsite. What's happening is that we will be implementing direct remote tape drives to our second datacenter so that our offsite volumes will appear as a local library with local drives and tapes.

Re: Reclamation question
In looking at this further, I came across this in the support web site . . . . Technote 1114948 Reclamation for primary stgpools is performed on a volume by volume basis. That is, each volume is reclaimed as it's own reclamation process. With copy stgpools, all eligible volumes are reclaimed as part of a single process. When reclamation of a single, primary stgpool volume completes, the TSM Server will check the reclamation threshold for that stgpool before looking for additional volumes to reclaim. If the reclamation threshold has been increased to 100%, no further volumes in the primary stgpool will be reclaimed. Because all copy stgpool volumes are reclaimed as a single process, the only time the IBM Tivoli Storage Manager (ITSM) Server checks the reclamation threshold for the copy stgpool is when the reclamation process begins. At that time, all of the eligible volumes are queued up to be reclaimed and the ITSM Server does not check the reclamation threshold again until the process completes. This clearly says that the difference in reclamation processing is by the type of pool, not the access state.

Re: by-hand reclamation question...
Ars, Maybe I am missing the point here, but I will offer a solution based on what I understand your situation to be. Apparently you are using to different copy storage pools one for off site and one for on site, correct? I am going to assume you are using DRM or at least I am hoping you are. The simplest thing to do would be to simply use MOVE DRM to mark all volumes in your on site copy pool as being in the vault just prior to the reclaim. If you use the WHERELOcation parameter you can limit this move to only those volumes outside of the library. This will force TSM to use the primary copy of the data to do the reclamation. When the reclamation is completed you can then move all the tapes back on sit. This should be a relatively easy thing to script and I believe it will solve your problem. -- Regards, Mark D.

Output of command redirected to file 'QCON3'
Massage qcon3 and sort it to find duplicate names which indicate a tape chain.
The thing that needs to be massaged is to put the volume name on the output

unwrap long filenames.

If I understand your scenario correctly, then I think I've run into this.
My not-so-elegant solution was to start an 'audit volume' on the tape that
I intend to run a 'move data' against. If it's the only tape needed, then
the audit will start up okay and can be cancelled; if there's at least one
other tape needed, audit will complain that a required volume is offsite,
specify the needed volume, then terminate. Unfortunately, audit only
specifies *one* required offsite volume, so you have to do another audit
after the needed volume is marked onsite in order to see if a 2nd offsite
volume is needed.
I thought about trying to script this to the point where you could at
least know all of the volumes needed before ever inserting any tapes; that
way you could make only one 'offsite trip'. I think that would involve
marking a volume onsite before inserting it, attempting the audit,
capturing the needed volume name if the audit fails, cancelling the audit
if it doesn't (and maybe dealing with a failed mount?), etc. I never
actually spent any time coding/testing this, though.
This is admittedly very ugly; I tried getting IBM to give me some SQL that
could *quickly* determine the needed volumes, but was told it's not
possible. I'm not sure why...presumably it has to do with the it's not
really a relational db, and the SQL interface is only a convenience good
for some things business; all I know is that audit knows *immediately*
which other volume is needed.
Fortunately for me at least, I no longer have a need to do this sort of
thing.

by-hand reclamation question...
Greetings. I've got another reclamation-related question. I've got some copy stgpools which, though they are theoretically onsite pools, I'm having to check out of the library. In the past, I've worked with this by re-inserting the volumes which are interesting from a reclamation perspective, but there's a problem with this strategy: In order to reclaim a given volume, you really need three different ones: The target volume, and the volumes adjacent to the target: The one with the other half of the aggregate which comes first on the target volume, and the one with the other half of the aggregate that comes last. I don't think I've been able to find a way to find which volumes these are without actually running the expiration or move data and failing the mount. Is there a good way to find this information out? Ideally, I'd like to have my temporary tapehandling methods go something like: (early in day) Check in all volumes necessary for optimistic reclamation workload (day) Reclaim volumes (late in day) check out all copy-pool volumes which are 'FULL' and in the library. Does this make sense? Anyone got a hole in that logic? - Allen S. Rout

Offsite reclamation question? [ LONG ]
Hi, all: I've got a question I've been wondering about, relating to how foresightful TSM is in its' offsite reclamation. I'll spin an example: TSM server 'SRV1' has three nodes NODE1 NODE2 NODE3 It's got stgpools PRIMARY : collocated . Volumes named Pxxx COPY: non-collocated . Volumes named Cxxx OFFSITE : non-collocated . Volumes named Oxxx Daily incrementals happen on all nodes. Tapes go offsite every day. OK, given that scenario, we know that the vast majority of offsite tapes have a thin slice of data from all of NODE1, NODE2, and NODE3. --- Known scenario --- So when an offsite volume O213 passes the reclamation threshold, the server begins building a new offsite volume O501. It mounts PRIMAY volume P001 (with node1's data on it) and makes an additional copy of those files from NODE1 that appear on O213, and are still interesting to the server. Then it mounts PRIMARY volume P002, does the same for NODE2, Then it mounts PRIMARY volume P003, does the same for NODE3. Now, new offsite volume O501 is ready to leave on the next truck. --- Unknown scenario --- Now, what if O214, O215, and O216 all pass the reclamation threshold? We know the server's going to start building O502. Say it picks O214 to begin with. When P001 is mounted, will the reclamation copy files from -all- the reclaimable offsite volumes, only from O214, or what? I can see pseudocode something like: - Pick an offsite volume to work on - From that offsite volume, pick a first onsite volume to mount - From that onsite volume, determine all files wanted for offsite reclamation. Copy them. This would be expensive in query time, but the alternative is a big-O N * M of tape mounts, which makes me shudder. But it would certainly be simpler to code.

Re: Offsite reclamation question? [ LONG ]
Hi, Overall... Normally a site will have one or more primary storage pools. These may be colocated to improve the efficiency of restores, depending on the site and its resources. These primary storage pools are copied to one or more copypools. The copypools are normally not colocated to save on storage resources. The copypools are checked out and sent offsite, and their status updated as offsite after the data is added to volumes each day. Then as the expiration process expires the data of the copypool volumes that are offsite, they are returned to the site and checked in and become scratch volumes.

Hi all, It appears my offsite non-collocated tape pool has more filling tapes than it has in the past. Does anyone know if tapes in a status of filling are being reclaimed or are only tapes in full status put in the reclamation process?

Re: reclamation question
Both full and filling are being reclaimed. I have found that because I have local tapes with errors on them, to reclaim some of my offsite copypool tapes, I pull in the copypool tapes that 'will not finish reclaiming' (less than 3% or so), check them in, and do a 'move data' on them. They turn into PENDING once the data has been moved. I send them offsite again, until they are 'EMPTY'. Doing this simi-regularly has recovered many tapes. -Original Message- From: Levi, Ralph [mailto:[EMAIL PROTECTED] Sent: Thursday, October 28, 2004 6:44 AM To: [EMAIL PROTECTED] Subject: reclamation question Hi all, It appears my offsite non-collocated tape pool has more filling tapes than it has in the past.

Re: reclamation question
Tapes can also fail to reclaim in you have RESTARTABLE RESTORES hanging around. In this case you will find in the server actlog: ANR1089W Space reclamation terminated for volume x -lock conflict. From a server command line, do Q RESTORE. You will see there are some restartable restores hanging around. When the users finish them, or their timer expires, the tapes will go ahead and reclaim the next time reclamation runs. -Original Message- From: Gabriel Wiley [mailto:[EMAIL PROTECTED]] Sent: Wednesday, March 06, 2002 1:04 PM To: [EMAIL PROTECTED] Subject: Re: reclamation question Tim, Occasionaly I will have a problem where a volume will show up as reclaimable and it won't reclaim.. I will try and delete the volume discard=yes(volume being a offsite tape) and it won't do it either. I do an audit volume XX fix=yes to resolve the problem.. XXX= volser number. You could also try moving data on the volume move d A00044 stg=NT_TAPE if nothing happens , look back in the actlog to find out what the problem is... I don't see any read/write errors ?

Re: space reclamation question
Quoting Zlatko Krastev/ACIT [EMAIL PROTECTED]: the one which is below the reclamation threshold (the source) - look at q vol and a scratch or private volume for the stg pool (the destination) - def vol or upd stg maxscratch=nnn Backup files are sometimes segmented and spread across two or more storage pool volumes. If a volume below the reclamation threshold contains one segment of such a file the volumes containing the other seqments will also be required as input volumes for reclamation. I don't know of any elegant way to identify the other volumes in such cases. The ugly way I am aware of starts by running a pair of query content commands with count=1 and count=-1 against the below threshold volume to find out whether that volume starts or ends with a segmented file. If it does, one can run similar commands against the other volumes in the same storage pool and look for matching file names.
Re: space reclamation question
We used to do this by starting a move data on volume XXX, then looking in the activity log for messages like Volume 12345 is expected to be mounted. Those messages listed the OTHER volumes that held pieces of files from volume XXX. Ugly... worked, though. -Original Message- From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED]]On Behalf Of Thomas Denier Sent: Monday, September 10, 2001 1:57 PM To: [EMAIL PROTECTED] Subject: Re: space reclamation question Quoting Zlatko Krastev/ACIT [EMAIL PROTECTED]: the one which is below the reclamation threshold (the source) - look at q vol and a scratch or private volume for the stg pool (the destination) - def vol or upd stg maxscratch=nnn Backup files are sometimes segmented and spread across two or more storage pool volumes.

space reclamation question
Hi all, Is there a way to predict which library volume will be needed to do the space reclamation? Thanks. Best regards, Phillip
Re: space reclamation question
Yep, the one which is below the reclamation threshold (the source) - look at q vol and a scratch or private volume for the stg pool (the destination) - def vol or upd stg maxscratch=nnn ;-) Sorry, cannot be more precise.
