reclaim stgpool
Hi *, We have recently started to use the reclaim stgpool command. What is the most efficient way to use this command ? How are users using the offsitereclaimlimit and threshold settings ? We are reclaiming tapes, but not nearly as efficiently as before when we would use the reclaim=60 parameter . We are at TSM 5.4.3 running on AIX 5.3 TL8.

Re: reclaim stgpool
We still use the thresholds instead of the reclaim stg command. I would make the switch if they added an endtime option as opposed to the duration it currently has. Our daily maintenance processes vary greatly in the amount of time they take to complete each day, so duration is completely useless for us. I would prefer the reclaim stg command because the process are actually canceled when the Duration lapses.

Re: reclaim stgpool
I built a stupid little script to compute the time in minutes from 'now' to our designated end-time. It then fires off reclaim stg commands with the calculated duration. Works OK for us.

Re: reclaim stgpool
a TSM script? or a shell script? If it's a TSM script, can you post it?

Re: Tape reclaim stgpool migration question/
It might be related to size of reclamation stgpool and transaction size. If reclamation have filled the reclamation pool to 75% and next set of files in inter-server transaction is worth 20% of reclamation pool size, you will have the pool filled to 75+20=95% before migration threshold is passed.
