Hello *SMers,
I'm having trouble with operating Dell 110T LTO2 drives in a PowerVault
132T library.

Environment:
- W2k3, HBA Qlogic 2340, FC attached Dell Powervault 132T library with 2
Dell 110T LTO2 drives
- TSM device driver for library
(http://www-1.ibm.com/support/docview.wss?rs=663&uid=swg21177112) and
IBM device drivers
for the drives
(http://www-1.ibm.com/support/docview.wss?rs=663&context=SSGSG7&q1=110T&uid=swg21082581&loc=en_US&cs=utf-8&lang=en)

I am able to define both drives and library, as well as paths, in TSM
sucessfully, but I'm having problems with write operations to the drive.
F.e., when I try to label volumes in the library, the tape gets mounted
in a drive, but no label is ever written and the process never ends (or
at least not within 20 mins). Tape stays mounted in a drive and never
gets dismounted. I've tried dozens of combinations of device drivers for
the drives, but never succeeded. I see no error in the TSM Actlog or
Windows Event log.

When I define library as RSM type (using native Dell device drivers for
both library and tape drives) and use RSM for media handling, everything
works fine.
I can easily label volumes, perform backups and so on. Again, when I
reconfigure the library and drive back to SCSI type and try to perform
f.e. a backup of TSM database using media labelled in previous step (via
RSM), the procedure repeats with the same result - robotics mount the
tape in a drive and nothing happens. TSM server is still waiting for
mount of a scratch media, eventhough the volume is already mounted.

I've tried to install TSM 5.2 even, but the result is the same.

It seems to me, that there must be a problem with device drivers, but
maybe I'm missing something.
Any ideas ?
