Missing /dev/st0 - how to create?

[galahad7]

Hi All,

I've recently installed Gentoo Linux 1.4_rc4 from stage 3. I've just now attempted to put a tape drive on this machine, however "ls /dev" shows that /dev/st0 and /dev/nst0/ are missing. There is no /dev/tape either.

Could someone please advise how I can add these /dev files.

Many thanks

Stephen

I am missing these too, they need to be compiled into the kernel I think - but I don't know which to select.

I will let you know if I find out.

I've chosen kernel options
SCSI support
SCSI tape support
SCSI lowlevel drivers <card I have installed>

Thanks for your reply
Stephen

For posterity... in case anyone reads this thread.

I'm using a LSI 53C0101 SCSI card.

When building the kernel I originally had the standard sym53c8xx option chosen. When I chose the sym53c8xx_2 (version 2) module and changed "SCSI tape support" from a module to embedded, then /dev/st/ and /dev/tapes/ directories appeared. Great, one or both of the choices did the trick.

Tried the devices out using
tar cv -f /dev/xxxxx /etc/<afiletobackup>
and found the one to use is /dev/tapes/tape0/mt

I got it working - and st0 showed up - even though its an IDE tape drive.
