Not RECLAMATION, but EXPIRATION processing where the management class retention policies are applied to all the version of a file and extra or old versions are expired. TSM keeps track of how much data remains on a tape volume after expiration and reports this my the "Pct. Reclaimable Space" is a Q VOL xxx F=D output. When you set the storage pool to RECLAIM=<something less than 100%> TSM compares each tape volume in the storage pool with this value. Volumes that have a "Pct. reclaimable Space" >= this value are reclaimed. Expiration processing is done automatically by setting the EXPINTERVAL in the server options file, or setting it to "0" and running it manually with the "EXPIRE INVENTORY" command.
Offsite reclamation takes "so long" because TSM is recreating the offsite volume from onsite copies of the files. SO you may end up with several tape mounts, tape prositioning just to read a single file. Onsite reclamation takes the volume to be reclaimed as input, copies all the "good" data from it to another onsite tape volume.

AFAIK during backup files are not 'marked' at all. They are just stored and during reclamation each file is compared to rules defined in its mgmtclass copygroup. That why reclamation takes so long. If you backup a file and according to *current* rules a version should expire, later update copygroup to retain more versions (or for longer period) and just afterward run expiration - the file should not be expired. If it is marked during backup/archive it would expire which would be against ADSM/TSM ideology and should be treated as bug. Jack, sometimes it helps to change reclamation/migration threshold to 100 and minute or two later to lower it. I've digged deeper to analyse why.

Jack, As TSM ages backup and archive data, the files only get 'marked' for deletion. You must run an EXPIRE INVENTORY command to actually flip the switch from 'marked' for deletion to deleted. Then your storage pool reclamation should work. That is, unless I am missing something too!!! 8-) John G. Talafous IS Technical Principal The Timken Company Global Software Support P.O.

My tape use is going up, but nothing is being reclaimed from my copy pool. I must have done something wrong, but where do I go to look for whatever is wrong first? What am I missing? I can find nothing in the activity log, and even when I do a update stg copypool rec=5 and it should recover a lot, nothing happens. Sometimes the process starts up, but will sit for hours and nothing gets reclaimed. Running TSM 4.1.5 on NT, with 3583 library and LTO drives. It has been working, but stopped earlier this week. ...
