You are correct, but in order for space to become reclaimable, it has to
have been expired and this occurs in the database, which results in the
object expired on tape. In our policy, we keep the last 3 inactive
objects plus one that is active. Older objects then expire and space on
the tape is reclaimable.

Re: [ADSM-L] Full tapes with low percent utilization
I am not sure that is quite right.
When a newer version of an object is backed up, the Client does "EXPIRE"
the object, but the object only "EXPIRES" from the TSM SERVER db
according to the retention policy (copy_group) bound to that object.
The data does not expire from the tape until it expires from the DB.
Or am I lost.

RECLAIM STGPOOL LTOPOOL1 THRESHOLD=60
This will reclaim all tapes that have 60% or more reclaimable space.
Reclaimable space occurs when you existing objects that were backed up
are saved again. The preivous backup of that object is expired and that
part of the tape is reclaimable. Tapes are reclaimed by creating new
ones without the expired objects. But this is a ongoing thing so you
should be running reclamation everyday after migration. You will also
need to run reclamation against your tapepools that are in the library
and against the tapepools stored offsite.

[ADSM-L] Full tapes with low percent utilization
Hi list,
I have several tapes on an IBM ULT-3580 library that show very low
percent utilization (see output below) but a FULL status....why does
that happens and how can I fix this?
