Problem using Ultrium-3-Tape on HP ProLiant-Server with Debian etch



Hello,
we are using a Server HP ProLiant ML370 G5 with a
SmartArray-P400-SAS-HBA and a HP StorageWorks Ultrium 920/448 SAS
Tape-Drive.
Our Problem is: Debian Etch does not recognize the drive.
Installing the standard-lenny-kernel does not improve the situation.

Below there are some informational outputs from the system belonging the
problem.

The SAS-Hard-Disks are operating perfectly (using the modules scsi-Mod
and cciss).

Can you give us any hint to fix the problem ?
TIA

Best regards
  Hubert Plaschke
