Can someone confirm that this is done immediately and not when
expiration runs? Maybe a client expired THE file that held a tape at 50%
and thus that tape went to 51% reclaimable.


very well possible. Alternatively, you could have a volume that was
being reclaimed, but reclaim failed for some reason, and after a few
days of (re-)trying, TSM finally succeded in reclaiming that tape.

David,

"I'll ask the obvious.  Any chance you copypool reached 100% triggering
a
reclaim?"

The reclamation ran on a primary storage pool.  There is nothing
*obvious*
that could have pushed ONE tape over the pool's 50% reclamation
threshold
during the midnight to 1:00 am period when reclamation launched.
Reclamation ran on that one volume only.  During our maintenance cycle,
which is running now, that particular pool can reclaim as many as 30
volumes.

Thanks.

Tab
