Is this the traditional type of copy storage pool, with volumes trucked to an offsite vault? The usual practice with this kind of offsite pool is to put a volume on the next truck out once TSM has written data on it. This minimizes the amount of data lost in the event of a data center disaster, but it results in a lot of copy pool tapes being sent to the vault while still in 'FILLING' status. Make sure the offsite tapes have the right setting for the 'ACCESS' parameter. I know of no way to target 'FILLING' volumes for reclamation, but you can target low utilization volumes simply by using a reclamation threshold not much less than 100. For example, if the reclamation threshold is set to 95 TSM will only try to reclaim volumes with less than 5 percent of the space on the volume occupied by unexpired files. This may include some tapes with a percentage utilization greater than 5 percent; the utilization reported by TSM includes unused space in aggregates that contain a mixture of expired andunexpired files.
