Hello to all,
I have two questions this morning but first I will update a little on my
setup since last week was a migration. I've migrated to an M80 with a 2way,
5gb memory, ssa 16x36gb drives, 6 - 3590's now in the 3494. I'm running AIX
4.3.3 and TSM 4.2.1
The first night TSM core dumped. I sent that right off to TSM support, who
one week later they still don't know why it happened. Seems there are others
having the same problem too. The good news is, since that first night, the
system has managed to stay up for me.
The second day I had some tape issues. TSM thought 24 tapes were unavailable
when they really were. There was an issue with mounting all of these tapes.
Seems as though TSM did not report them as unavailable, they were read
write, I checked. Once I forced them all to unavailable and back to read
write the problem went away. So far I have not run into any other issues,
but if I do I will let everyone know.

The first question I have has been hashed over before I know, backup sets. I
was told that once I upgraded to either 4.1.4 or 4.2.1 the backup set I have
hanging out there would go away. I ran a test backup set back in February,
and although I can query for it and it is gone, the volhist file and tape
are still there as you can see. So how does one get rid of these since they
don't seem to go away on their own?

The next question is Expire Inventory. Here is the output of a select
statement which shows how long Expire Inventory takes each day. I just got
the script so I have nothing to compare to, as it relates to the old server.
Does anyone have any statistics they can tell me as to how long expire
inventory takes on their system. Yes, I know there are a lot of factors to
take into consideration. For now, just figure I have the M80, a 2way, 5gb
memory, a 24gb database about 50% full. Does it take as long for other folks
to run the same process???

Last 2 days:

As always, thanks for help or info you can provide.
