/dev/st0 doesn't exist
I'm trying to setup a SCSI tape drive.
For the record it is an HP C1537A 12/24GB DDS Drive
This is the output of /proc/scsi/scsi:
Attached devices:
Host: scsi0 Channel: 00 Id: 04 Lun: 00
Vendor: HP Model: C1537A Rev: L610
Type: Sequential-Access ANSI SCSI revision: 02
If anyone wants to see it, the output of /proc/scsi/advansys/0 is at the
bottom of the message.
My problem is that /dev/st0 and /dev/nst0 do not exist. Ie: ls /dev/st0
would result in No such file or directory.
SCSI Support and my low level drive (advansys) are compiled into the
kernel. I'm loading the scsi tape support as a module.
modprobe st reults in:
Detected scsi tape st0 at scsi0, channel 0, id 4, lun 0
yet /dev/st0 is not there.
Is there another way I'm supposed to access the drive or do I need to
install a package that would set that up for me. cpio was already installed
and I tried installing taper to see what that would do. It didn't
accomplish anything.
My laptop, which has Redhat 7.2 because my debian 2.1 CD didn't have the
right drivers for my pcmcia network card and I was too lazy to make a CD
that had them (although I'm begining to regret that now). I guess that
bears mentioning that the machine that is giving me probelms is running
potato with 2.2.19. And the reason for mentioning RedHat was, an ls
/dev/st* there includes /dev/st0 through /st61 and a lot in between.
Also, just remembered to check some of my other debian machines to see if
they have any /dev/st0. Of the two that I checked, none of them have
anything related to st.
I'm thinking there might be something debian specific that I'm missing.
Any help would be appreciated.
