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.

I guess I got behind doing the reclamation. But that doesn't make any sense because the offsite pool and the onsite pool have the same settings and the same content. Only difference is that one goes off site. I use the same settings when I run reclamation on both pools but I run them at completely different times and the times don't overlap. When I run the onsite copypool script the process starts without delay. The same settings for the offsite copypool takes forever to actually kick off. I guess I'll need to keep a closer eye on things........ -----Original Message----- From: ADSM: Dist Stor Manager [mailto:ads...@vm.marist.edu] On Behalf Of Allen S.

I have > plenty of scratch tapes and mount points. Try running one at 99% and _no_ time limit, and expect it to run for days. There's a huge amount of bookkeeping work TSM does at the outset. If you've gotten yourself stuck somewhere, and lots of time has passed, you may have a large backlog. In that case, trying little nibbles is the only way to go. You could also approach this from the -OFFSITERECLAIMLimit--=--number_of_volumes- side, limiting it to just a few at a time. - Allen S. Rout
