  Assuming it was detected as the first SCSI tape drive in the system:

	mt -f /dev/nst0 status

> Maybe a write test command?

  Same assumption:

	cd /
	tar --create --one-file-system -f /dev/nst0 etc
	mt -f /dev/nst0 rewind
	tar --diff -f /dev/nst0

(To those who know: Yes, I know the "mt rewind" part could be eliminated by
using the rewinding tape device.  The above tests the ability of "mt" to
control the drive.)

  See the following manpages for details: st(4), mt(1), tar(1)
