Hi

I've got a IBM xSeries 225 with RAID 5i and a IBM DLT/VS Tape Drive.
As Operating System i've got Suse 8.0 with KDE installed.
Now here's my Problem: The Tape Drive is recognized by the RAID-Controller, but not by Suse. Tape Drive ist on SCSI BUS 2 ID 6. Some extracts from the console:

$ mt -f /dev/st0 status
mt: /dev/st0: No such device

The Hardware should be ok (Device and cable have been changed, RAID-Controller/BIOS have newest Firmware und a IBM-Technician tried to fix it for 2.5 hours, seems to be a software problem) I've done a new Installation of Suse and set BIOS and RAID back to factory settings.. didn't help either.

One possibility may be an update of the LSI driver, I will test this soon.

Does anyone has a idea/suggestion? Could it be a problem with drivers that Suse uses? how can i check this?

thx
schaf

p.s. please explain in an easy way.. i'm quite new to linux.

Here a part of dmesg after starting. Unfortunately I don’t know Linux very well so I cant see so much in this, but if I’m right the tape drive isn’t recognized here.. but RAID-Controller recognizes it.

maybe this helps understanding my problem
