Topic: Problem getting Tape backup to work

[Gryf]

Hi!

I cannot get the tape backup to work. My Tape streamer is a Sony SDT-5000 scsi tape streamer.

For me it looks like the /dev/nst0 dont exits!

Here's what e-smith email'ed me:

What sort of scsi host adapter do you have? Do you have the correct module loaded via the modules.conf for it? Check for a line similar to "alias scsi_hostadapter ncr53c8xx". If you have that line try a #modprobe ncr53c8xx. I also have a module loaded called st which I think relates to the tape streamer. Try doing #insmod st.
