getting warmer.
How about trying
tar zclpf /dev/nrst0 .
instead - the /dev/nrst0 refers to the first _non-rewinding_ (this is
important if you're doing multiple consecutive operations to tape) scsi tape
device.
You could also try looking at the contents of (I think) /proc/devices and
/proc/scsi to see what is there. Also, try using the mt command on the files
/dev/*st* and see which ones are actually valid for your system.
(ie, do mt -f /dev/nst0 status etc).
