Yeah, I do it regularly, at least once a week.  We also have a
replication server, but I like the security of having them on tape too.
I usually run the reclamation after the backup is done.

Hi Martha!

Has the storage  pool been backed up to a copy pool?
If the DEDUPREQUIRESBACKUP option is set to YES (default), reclaim can't happen 
until the BACKUP STGPOOL is done.

Hi Martha,

have you run "query content" on some of the volumes to see, if they are really 
empty?

We just installed TSM 7.1 during the summer and have been working on
migrating our backups over from our old v5.5 system.  We are using
deduplication for our main storage pool and it seems to work great.
However, I'm concerned about how it is using the "volumes" in the
storage pool.  Since we never ran v6, I don't know if this is "normal"
or if we have stumbled upon a bug in 7.1.  So, I figured I'd ask on
the list and see if any of you have some insight.

Our dedupe storage pool is dev class FILE, of course.  It is set up to
acquire new scratch "volumes" as it needs over time.  Originally, I
had the max scratch vols allowed at 999, which seemed reasonable.
After about a month, though, we hit that max and I had to keep raising it.
When I query the volumes belonging to this pool, I see many, many of
them in full status, with pct util=0:
Volume Name                             Storage Device
Estimated       Pct      Volume
                                                     Pool Name Class

Literally, hundreds of them.  I run reclamations, but these volumes
never get touched nor reclaimed.  Seems to me that they should. I've
gone over the admin guide several times, but have found nothing
touching on this.  We just applied the 7.1.1.0 updates, but that has
not helped either.  If I do a move data on each, they will disappear.
However, more will return to take their place.  Anyone seen this
before, or have any suggestions?
