John,

A question on reclamation....
I have the following occurring constantly during reclamation:
05/17/05 11:41:12 ANR1040I Space reclamation started for volume
304048,
storage pool EAGLECOPY (process number 8619).
05/17/05 11:50:02 ANR1163W Offsite volume 304048 still contains
files which
could not be moved.
05/17/05 11:50:02 ANR1041I Space reclamation ended for volume
304048.
This has occurred for 8 tapes in the last 24 hours.
Why is TSM attempting to use this tape for reclamation when it has been
labeled as "vault" and is "offsite"?
Thanks!

I always say, "The only naïve/stupid/dumb question you have is the one you
don't ask."
1.) Previously answered by Mr. Stapleton
2.) There are ways to manually audit (and I have done this) the various
entries for TSM Tapes. Tapes are either in the DRMEDIA inventory and
offsite, onsite and used by a storage pool, offsite and unused or onsite
and unused. This is a complex process and must be approached carefully.
But very doable!!! Contact me if you desire additional information.
3.) Run an SQL SELECT statement to list your environment's tape inventory.
I like to look at volumes used by STGPOOL as well as TSM Library inventory
levels.
A: Volumes used by STGPOOL:
select stgpool_name,devclass_name,count(*) as VOLUMES from volumes
group by stgpool_name,devclass_name
NOTE: This will list volumes for ALL device classes, not just
tape.
B: TSM Library inventory:
select count(*) as Volumes,status,library_name,owner,last_use from
libvolumes group by library_name,owner,status,last_use
NOTE: This will report volumes used in a TSM Library sharing
environment. If NOT in library sharing, you may have to alter accordingly.
Watch your stgpool volume utilizations from #3.a and your scratch count
availability from #3.b. Hopefully, you are able to maintain a healthy
scratch count. If not, these queries will let you know. You could also add
a report to show reclamation opportunities by storage pool to assist
determining where to focus your reclamation efforts.

Subject: [ADSM-L] Scratch tape questions
I hope these aren't "naive" questions.....
1 - How do I know if there are any tapes at the offsite storage that should
be onsite and be available for scratch?
This includes DB backups and normal backups.
2 - How would I tell if TSM is actually processing tapes correctly?
(e.g.) From vault --> vault retrieve --> courier --> courier retrieve
3 - How do I know if reclamation is actually increasing the scratch count?
Thanks!
