This is why I do not use the reclaimation process. I have written a process that does MOVE DATA vvvvvv reconstruct=yes commands for the volumes that have less than a reclamation number. I set the reclamation in the storage pool to 100 so they will not reclaim.
Then I can run as many simultaneously as my drives can handle, usually 5 to 6. Yes, from the same storage pool. We actually do this because we use closed box and the tapes may return before they are empty, so 14 days before there return I move the data to new volumes going offsite. I also have a second threshold. If the tape has been offsite more than say 14 days and is less than say 10% utilized I reclaim them as well. There are many beauties to this process and only a couple negatives. You get your tapes refreshed at the offsite no matter what. You can use closed box. Keeps the tapes full at whatever level you want. Allows you to have a built in scratch pool for disaster recovery. Keeps collocated volumes down to a minimum (fewer mounts). On the negative side, it requires tape drives. The process is home grown using TSM selects and AIX KSH scripts. We use separate pools for database and exchange backups or similar type data. Those backups do not have to be recycled before return because there are always full copies of these offsite. Maybe ITSM development will take a look at doing something like this in the future. This is the case for smaller storage pools and more of them. Paul D.

Right now, we have 200+ volumes in that pool. Normally, threshold is set at 60% and I get maybe 8 or 9 volumes returned after processing for 7 hours (on beefy AIX, with TSM at 5.1.5). Lately I've tried setting the threshold at 99, then 98, then 97, etc., but I don't see much improvement in overall freeing up of tapes. It appears that most of the time is taken up with mounting input volumes. Even though we have a 3494, I'd say 80% of the time is spent waiting for tape mounts. Is there any way to get space reclamation to free up offsite tapes faster? Note, for my onsite tape pool, I do not see this problem (e.g., I can easily free up 30 tapes in 5 hours or less).
