Michael,
Why has your tape got a status of filling ?
That would be a reason why it would not return to scratch
Are all your problem tapes like that?

We are having a similar problem with our server (v4.2.2.12, on OS/390
v2.10).
Here is my problem:
The reclaim runs, and ends, but the tapes are not being updated as empty.
If I run an audit of the tape volume, it will then go to empty, and be
deleted during our next MOVEDRMEDIA command. Here is an expamle of one
tape that we ran the audit on:
Before Audit query:
Volume Name: 321343
Storage Pool Name: DEV_TAPEOS
Device Class Name: 3590_OFFSITE_COPY
Estimated Capacity (MB): 9,216.0
Pct Util: 0.0
Volume Status: Filling
Access: Offsite
Pct. Reclaimable Space: 100.0
Scratch Volume?: Yes
In Error State?: No
Number of Writable Sides: 1
Number of Times Mounted: 2
Write Pass Number: 1
Approx. Date Last Written: 08/01/2002 01:20:28

After Audit query:

I do have an ETR open with IBM on this issue.

System is TSM 4.1.2.0 on AIX 4.3.3. I run reclamation daily on my tape
backup copy pool, but the backlog of unreclaimed tapes continues to grow
(as determined by SQL select looking for volumes in the pool that meet my
reclamation threshold - 60%). The space reclamation process mounts a
number of tapes, and a good number of bytes get moved, but the count
continues to grow. My onsite tape backup pool does not suffer from this
problem. I'm not seeing the number of ANR1341I messages (Scratch volume
<volume name> has been deleted from storage pool <storage pool name>) that
I would expect. Nor, am I seeing the expected number of ANR1342I messages
(Scratch volume <volume name> is now pending - volume will be deleted from
storage pool <storage pool name> after the reuse delay period for this
storage pool has elapsed). I should be seeing one or both messages for
each offsite volume reclaimed, right? Because my offsite tapes are not
getting reclaimed in a timely fashion, I'm faced with a lack of scratch
tapes every day. Any ideas anyone?
