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.
