In 5.2 and below, Offsite Reclamation is handled differently than onsite. Onsite reclamation starts with the most-reclaimable tape (99.9) and does them one at a time.
Reclamation for tapes marked OFFSITE (usually your copypool) is different. Since TSM must mount the ONSITE/primary pool tapes to do the reclaim, it tries to make sure each input tape is mounted only ONCE. So when offiste reclamation starts, TSM gets the list of ALL tapes above the reclamation threshold, mounts the first input tape, and tries to reclaim all the files on that input tape. The result is that you reclaim a little of EACH of the offsite tapes with each input tape mount. The usual circumvention is to set your offsite reclamation threshold to 98, let reclaim finish, then set it down to 95, then 90, then 85, etc. Otherwise you may NEVER finish.

I did not know if it started with the 70% as you said but I know that it does not start with the 99.9%. We have been having trouble getting reclaim to finish. Since it starts with the 70% and does not finish, over time we have a lot of tapes offsite which are 99% reclaimable. And I do mean a lot. I have actually created a process that does a move data on these to try and get them reclaimed. Our version of the server is old and we are in the process of upgrading to 5 something and I was hoping that that was going to fix the problem. Well I guess not. It has been a real problem for me. -- Phillip 320-4462 -----Original Message----- From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED] On Behalf Of Meadows, Andrew Sent: Monday, November 21, 2005 12:50 PM To: ADSM-L@VM.MARIST.EDU Subject: [ADSM-L] Reclamation I was wondering if anyone else has noticed this same issue and if there is anything that I can do for it. I am running on version 5.3.1.6 on AIX 5.1. Storage pools in question are LTO gen 1 Scenario: Copypoola has 50 volumes that are over 70% reclaimable with the percentages ranging from 70% to 99.9% reclaimable. If I start reclamation for copypoola with rec=70 (upd stg copypoola rec=70) it will start with the volumes that are 70% reclaimable and work its way up. This doesn't make sense to me wouldn't you start with the 99.9% reclaimable volumes first? If I do this for my onsite pools it starts the logical way with 99.9% and works its way down. Has anyone else noticed this and is there something I am doing wrong here or is this just the way it is. ******************************************** This message is intended only for the use of the Addressee and may contain information that is PRIVILEGED and CONFIDENTIAL.
