Dear Listers,

I really hope that I'm not OT.

While successfully using amanda on several machines I have a single
server/tape drive, which refuses to switch of hardware compression.

I read the threads several weeks ago in this list concerning compression but
all my experiments failed (see below). Even some emails with Tandberg didn't
show a solution (the support was really nice but no progress).

I am using SuSE 9.1 with amanda-2.4.4p2-49.

minerva:~ # dmesg | grep scsi
scsi0 : Tekram DC395(U/UW/F), DC315(U) - ASIC TRM-S1040 v2.05, 2004/03/08
Attached scsi tape st0 at scsi0, channel 0, id 3, lun 0
Attached scsi generic sg0 at scsi0, channel 0, id 3, lun 0,  type 1


This "Can't write mode page." below drives me crazy. 


minerva:~ # mt -f /dev/nst0 erase
minerva:~ # mt -f /dev/nst0 rewind
minerva:~ # mt -f /dev/nst0 datcompression
Compression on.
minerva:~ # mt -f /dev/nst0 rewind
minerva:~ # mt -f /dev/nst0 datcompression 0
Can't write mode page.
minerva:~ # mt -f /dev/nst0 datcompression off

minerva:~ # mt -f /dev/nst0 datcompression 1
Compression on.
minerva:~ # mt -f /dev/nst0 status

Is there anybody out there who encountered and solved this issue?

Thank you very much and best regards
Uwe
