[expert] SCSI tape drive

[Anonymous]

I would like to know how to use a tape drive connected to a SCSI Adaptec
AVA-1505.
The SCSI card is configured and recognised by the system, using the 152x
kernel module.

The thing is, I'm not able to access the tape drive in any way: I tried
to mount /dev/st0 (which should be the first SCSI rewindable drive) and
it doesn't work (error: "not a block device"). The MAKEDEV script
doesn't seem to work too...

Help me, please help me...
Thank you in advance.
