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. Thanks again! -----Original Message----- From: ADSM: Dist Stor Manager [mailto:ads...@vm.marist.edu] On Behalf Of Huebschman, George J.

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!
