Eric,
I would first check to which stg pool these tapes belong. After that I would
check if there is any data going in that stg pool. If not, then check why there
is a stg pool without have any data going into.
If so, check what data from which node is on these tapes (q content count=xx).
Maybe collecation on this stg pool is turned on and the client has directed his
data to another stg pool. Or maybe the pool has had collection turn on which is
now turned of. In that case, just do a move data on these tapes.
Regards,
Karel

Subject: Weird tape utilization
Hi *SM-ers!
I have found something very strange in our TSM tape utilization.
I found several primary storage pool tapes which should be used for data,
but which are not.
For example, one tape has a read/write, filling status with a utilization of
about 3% and about 23% reclaimable. However, the last written date is
September 15, 2003!!!
I checked all other servers and they all have several tapes in a filling
state with a last written date several months ago.
I really cannot explain how this is possible. Does anybody know what's wrong
here? The tapes have no error state, nor did they have in the past.
Thank you very much for any reply in advance!
Kindest regards,
Eric van Loon
