Re: Space reclamation runs, but tapes don't free up

Paul:

What is the exact syntax for auditdb? I've seen you mention it twice
now. I'm on 4.1.3 server (migrating to 5.1.1.6 tomorrow!) and don't
see this mentioned anywhere. This is part of 4.2 and later?

johnn

My recommendations is for people to get to 4.2.2.12 or higher for those of
us on 4.2 and get the backupgroups cleaned up before attempting a 5.1.1.6
migration.  This probably includes running an auditdb before starting the
ugprade as well.

There is a known problem opened with IBM on this...  We were told to upgrade
to tsm 4.2.2.4 or higher...this seemed to clean up most but not all these
problems...  If you q content on the tape it is empty, yet if you try to do
reclamation or delete it you are informed that there is still data on it....
We were told we would have to issue an auditdb to clean it up...this would
knock our production server off the air for over 27 hrs...so we opted no to
do this....

When we tried to upgrade from tsm 4.2.2.4 to tsm 5.1.0.0 we experienced the
following problem:

Item PQ64254



  APAR Identifier ...... PQ64254       Last Changed..02/09/12
  ANR9999D IMINIT.C  GROUP.MEMBERS ERROR 8 UPGRADEDB

We were informed to upgrade to 5.1.1.4 or higher and run a cleanup
backupgroups command....this also fixed nothing....

I have an additiona PMR opened with IBM on this problem and am waiting to
hear back...

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:

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?
