Richard,

The following command will reclaim tapes when they are 70% empty/30% full and 
run for 5 hours. It will not alter stgp settings.
As other have suggested, I run this in an admin schedule.

Reclaim stgp 'tapepoolname' th=70 du=300


Scott

Okay...  but either way, how does one then execute a manual reclamation process 
to get these tapes back at a certain threshold then?

Hi Richard,

    Percent utilized is not the same as percent reclaimable.  They're apples 
and oranges.  If you use pct_reclaim, you'll get what you want.  : )

I am using a SQL query to query how many tapes to be reclaimed at a certain 
level

Select count(*) from volumes where (stgpool_name='tapepool' and 
upper(status)='FULL' and pct_utilized < 99)

Jim's command alters the storage pool settings for reclamation (for the 
threshold and number of reclamation processes to run).

I'd guess that your "reclaim stgpool" command isn't working because none of the 
volumes in that pool have 99% reclaimable space.  Your 86 tapes that are 99% 
utilized may not have any reclaimable space, or may have some amount less than 
99% reclaimable space.  In other words, percent utilized is not the same as 
percent reclaimable.

You don't indicate how you consider a tape to be reclaimable.
