I have a set of perl/ksh scripts that have automated this.  They work well.

        Yes, I believe that that's right, reclamations are one per
storagepool.

        The only way I know to get around it is to write a script/select
statement to look for the tapes that are the least utilized and do a "move
data" on those tapes. I have not automated the process, but have a simple
select that gives me a list of all the tapes and the "pct_reclaim" from the
volumes table. The "pct_reclaim" is the opposite of "% utilized", so it's
kind of a "% empty" value.

select volume_name, pct_reclaim, stgpool_name from  volumes where
status='FULL' order by 3,2

        I run this script when I want to predict how changing the
reclamation threshold on a storage pool will effect processing. i.e. It will
show me how many tapes are above a given threshold and would be reclaimed.

Thanks,
Ben

Donald,

As far as I know, only one reclamation process per stgpool!

Is there a way to have multiple reclaim processes for the same storage pool?
It seems silly to have an 8 spindle library and only use two of them to try
to keep up with my reclaim processing.
