Hi *SM-ers!
I found something very strange on one of my TSM servers.
When I issue the following command:

select stgpool_name as "Storagepool",sum(physical_mb) as "MB" from
occupancy group by stgpool_name

I recieve the following output:

Storagepool             MB
------------------              ---------------------------------
DL_LBU3_CPY_1   26489427.98
DL_LBU3_PRI_1   27658559.10

However, when I issue the following SQL statement:

select stgpools.stgpool_name as "Seq. Storage Pool",
count(volumes.stgpool_name) as "Volumes in Use" from stgpools,volumes
where (stgpools.stgpool_name = volumes.stgpool_name) and
(stgpools.devclass <> 'DISK') group by stgpools.stgpool_name

I receive the following output:

Seq. Storage Pool       Volumes in Use
------------------              --------------
DL_LBU3_CPY_1   425
DL_LBU3_PRI_1   356

So, although the copypool (DL_LBU3_CPY_1) contains less data, it uses
more tapes!!!
The tape size is identical, reclaim runs fine (60% for both
storagepools) and reuse delay is identical too.
I'm lost here...
Does anybody have any idea why the copypool uses more volumes volumes
than the primary pool?
Thank you very much for any reply!!!
Kindest regards,
