Debian Tape Drive not detected (lsmod shows st)?


Hello all,

It is the first time trying to use a DAT (on SCSI a controller) tape drive on linux.
Unfortunatelly, the tape drive is not available.
Here are some info:

Code:
# cat /proc/scsi/scsi

Please, can you provide any suggestions?

And in case this is fixed (don't know how right now), since it is my first time with DAT, is there any nice open source tool that is well known today to handle full/incremental backups and restores on DAT from the console (not GUI)?
I mean a tool providing the user a more friendly interface than tar to be use for restore by the operators and be able to work as a daily cron job, too.

TIA.

Regards,
G.

I do not see the drive being recognized by the OS.
Does the SCSI controller BIOS detect the tape drive during POST?
Is the SCSI chain terminated correctly?
Make sure the tape drive ID is not set as either of the hard drives.
What is the make/model of the tape drive?

Not recognized by the system is also what I understand from the above. I do not have physical access to the system to see BIOS messages. I will visit the computer room hosting the PC, soon and will post those info.

Thank you...
