I think the confusion comes from the fact that the client log says
"Expiring-->" when it is only "In-activating" the file

The difference is ACTIVE vs INACTIVE, then EXPIRE

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?
