Hello All!

Thanks for your help!!

I am implementing TSM 5.5.1 on Windows 2003. I have added a client at
version 5.5.1 as well. The library is a TS3310 with 4xLTO4
drives The management class points to a DISKPOOL as it destination(info
below). Diskpool has 10 volumes.
But when I start a backup, the sever immediately mounts a volume and
appears to write to both the DISKPOOL and the next storage pool (ONSITE).
When it is all said and done, most of the files
land in the DISKPOOL but some land in the next storage pool (see q occ
output below).

Additionally when the server is writing the data I get continuos open/close
volume messages in the activity log (see below) while the server is writing
the data.
I have tried various things but none seem to solve this. Due to the limited
number of drives they have I need the disk pool to work as it should
otherwise we
will never be able to service all of the clients during the backup window.
Any clues?
