You can start by setting the Reclamation Threshold on your DRM pool to 90.
TSM will make a new copy the from the primary pool to the copypool. Then
request the return of all those DRM tapes with a status of VAULTRETRIEVE.
Once you have gotten thru the backlog, start doing this on a regular
schedule, choosing a reasonable figure for the threshold (I use 75 as a
figure that fits my processing window).

Subject: [ADSM-L] Ho do I reclaim copypool volumes
Hello ALL,
Thanks for your help!
I am at a new job and the copy pool in the TSM instance here has been
collocated previously. The admin thought it was collocated by group but
each group only had one member so it is really collocated by node I
think. The collocation has been turned off for a couple of weeks now. I
am not sure if that is part of the problem. The IBM doc really doesn't
have any practical examples of this that I can find.
The issue is: There are 900 or so volumes in the offsite vault via DRM.
Over half of these are less than 10% utilized. The scratch pool is
dwindling and I need a way to reclaim some of these volumes. The company
also has a DR test scheduled this summer and I would like to reduce the
number of offsite volumes so the DR process won't be so cumbersome.
What is the best way to consolidate this copypool onto less volumes. I
know the pending ones will be returned at the end of the reuse delay on
the pool and/or the DB backup expiration in DRM. I would think the that
pending volumes would be the only ones that would have a 0% utilization
but I have FULL and FILLING volumes with 0% utilization.
EX: ( sample of the volumes)
