RE: How do I configure Tape Drive

[Robert Jackson <rab walkermartyn co uk>]

Hi Art,

Forgive my ignorance! I seem to have a whole bunch of
devices set-up by default within the /dev directory for tape
drive use (e.g., /dev/nst0). However when I go to use the
device name I get the following error message displayed:
/dev/nst0: Permission denied. I have tried running the
command as 'root' and I now read and write from the tape.

I would like however to allow other users use of the tape. Not
just the 'root' user. Is this possible? If so how can I do it? Is it
just a case of using chmod on the device file?


TIA,
Rab.

I have an external SCSI tape device.  Here's how I do backups.

 mknod  /dev/st0     #  Creates the /dev/st0 file.  My SCSI device is the
first one on the SCSI ribbon for the adapter card.

mt -f /dev/st0 rewind   #  Moves the tape device to the beginning of the
tape.

dump -f /dev/st0 /dev/hda1  #  Dumps everything on the /dev/hda1 IDE device
the the tape.

Check you man files for more details and additional options.

restore -ivf  /dev/st0   # To restore.  I don't have to partial restores at
this time but the option does exist.

Hope this helps you get started.

Best Regards,
  Art
