I believe I may have the same problem.  It was a TS1120 to TS1130
upgrade.  Pools were appropriately renamed and created and a new
devclass created.  Maxscratch - plenty.  Bumped reclamation values all
around on onsite and offsite pools and still no reclamation.  Mount
points verified and available.  As I did all of this I was running
migration processes and copy process of offsite pool - but I still had
tape drives available to run reclamation

Before I left last night I activated reclamation commands for the middle
of the night when there were minimal to none admin processes (that use
tape drives) going on and it worked.  So it appears that my situation is
similar to yours and that reclamation works when no other processes are
running.

I find that strange ---- wondering if it is a bug.

Thanks for everyones help thus far -- much appreciated.

Seen this to - adjust reclaim percent and # of processes (TSM 5.5.2) yet
no reclaim runs.  I did get it work and it seems the only way I get it
to work is make sure there are no other processes running against those
pools like a backup stgpool or migration (depending if you're reclaiming
primary or offsite vols. )

Also make sure your Maxscratch on your stgpool is set appropriately )ie
there's some left between maxscratch and maxscratch used)

If you are trying to get TSM to move the data to a new Tape Format
(increased density and/or tape type) you would be better served to run a
move data command.  I'm assuming you have created a new storage pool if
you've gone to a higher capacity drive type.  However, 99% means that
the tapes have to be 99% reclaimable, or only have 1% utilization.

Have you tried bumping the reclaim threshold down to say 90% and see
what happens?  Also, I'm assuming that TSM uses the new drives just fine
for other types of processes (such as migration, storage pool backups,
etc.)?

Just so there's clarity you might want to give a general idea of how the
old and new storage pool situation is laid out, and what you mean by
"upgraded tape drives"  (could just mean newer drives of the same device
type).

We recently upgraded our tape drives.  I have verified that the new
device class has a sufficient # of mount points, we have plenty of
scratch volumes assigned to the tape pool.  I run a query and see

where

we have 36 possible tape returns running reclamation at 99%.  I also
verified volumes were in readw status.
I manually adjust the stg pool to desired reclamation value and

nothing

happens.  No error message ................ no mention of reclamation
in the actlog ....... zippo.  Tried both an onsite tape pool and
offsite
copypool.  Frustrating.   What am I missing?

thanks,
M
