If I understand you (David Longo) correctly, to are saying that while
*waiting* for the offsite tapes to arrive, TSM somehow performs space
reclamation and shuffles the data to new tapes. You are then left holding
media which does not contain the data you wanted.
Where does TSM get the original to perform the space reclamation, if the
onsite
copy is damaged and in need of a 'recover volume'?
Consider the following: When do you notice a media failure? When space
reclamation fails (or a node restore fails). If it fails during space
reclamation, the system hungrily retries reclamation. Within a very short
time of the offsite volume being checked into the library, TSM realises the
the data it was trying to reclaim is now availabe, and performs
immediate reclamation. No coincidence that the volume you want is the one
that gets reclaimed.
I would suggest turning off space reclamation of the OFFSITE storage pool
while
the recovery tapes are in transit and more importantly, while they are in
the
tape library. Turn it back on once the recovery is complete and you
should be ok.
Just another 2c.

After running the preview for restore, we mark all needed volumes as
unavailable. Both onsite and offsite ones. This has usually made them
static enough to not have a problem at restore time.
Just my 2 cents worth.

Have had that happen. Reason is this is a dynamic system with expirations
and reclamations running. By the time you got back the tapes requested, the
data on some of them was somewhere else according to the TSM DB. Run the
"preview" again. I've had several out of about a dozen or so restores where
I needed to make a "second pass" to get everything.

Had this happen again yesterday.
server 4.2.1
platform solaris 8
storage 3590-b drives in ibm 3494 library.
Issued the "restore volume" with wait=yes and preview=yes Captured activity
log, but when I did the restoer, it called for two other volumes. I really
don't think I missed it.
Anyone have an idea or a script for determining needed offsite volumes for a
restore?
Thanks for the help.
