Mel,

We were having some trouble in the same area.  Let me explain our
situation.  We where moving our diskpool the tape, every morning, and in
the afternoon, we performed our offsite reclamation for all our offsite
tapes.  What happened is we started to have errors, and the offsite
reclamation would fail.  In the server error log there was reported an
invalid attempt to free memory.  So I did some reading on the error, and
I learned that if the offsite reclamation is looking for a file that it
needs to reclaim the offsite tapes it must be on a tape.  If it finds it
on disk it will start to have problems.  So once I made sure that the
migration was completed successfully our offsite reclamation started to
work fine.  However, our migration eventually failed completely due to a
faulty controller card.  We replaced the controller card and everything
works nicely.  Here is some links that might help.

I know you are running 5.3.2, and it has said it should be fixed.  You
never know, IBM releases things too early!

Hope this helps!

Lately I have been having problems with TSM running offiste space
reclamation.  I have it scheduled to run reclamation on the offsite
storage pools in the evening, and it seems that every evening, I start
getting read errors as well as tape drive issues.  This only occurs
after the schedule kicks off.  I have copy stgpool processes that run
during the day that have no problems, and all the drives function fine
during that time, so it does not appear to be a drive issue.  Also, it
does not appear to be a tape issue either, as I have repeatedly marked
the questionable tapes as unavailable, only to have new tapes with
problems the next night.  Anyone else experiencing this?
