Hi Richard,

    The previous command that I gave you will work for this; however, you
will want to reset the reclamation threshold back to 100 when you are done
or the process will run automatically any time there is a tape that exceeds
the threshold and you may or may not want it to run at that time depending
upon which other processes are currently running and how many resources
(tape drives) are already in use.

   It is usually better to make this process part of a script that will run
the housekeeping processes at specific times and in order.


    Jim

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.
