[ale] SCSI tape problem

[James P. Kinney III]

If you do 'cat /proc/scsi/scsi' , you will get a list of known scsi
devices on your system. /dev/st is often a symlink to the actual device.
It can also be an environment variable. The actual device is stx or
nstx, where x is a number starting at 0. nst0 is the first non-rewinding
scsi tape device and st0 is the first rewinding version. They are both
the same physical device. 

To use the the device at a low level, us the "mt" commands. man mt will
tell you what to do.

You can make a symlink in /dev/ as you want. I find the nst device to be
more useful for my stuff than the st version. If you use the st version,
the tape drive will write from the fist command, then rewind the tap and
write the next command. So the second tar cv bar/ command will overwrite
the first tar cv foo/ . This is usually a problem.
