"nsrmm -C" will give you device status for all drives as well as tape
status for each:

(nothing) mounted on dlt7000 tape /dev/nst0
dlt7000 tape tape.004 mounted on /dev/nst1, write protected

- or -

8mm AIT-2 tape 010046 mounted on /dev/nst0, write enabled
8mm AIT-2 tape 010083 mounted on /dev/nst1, write enabled
8mm AIT-2 tape 000000 mounted on /dev/nst2, write enabled
8mm AIT-2 tape 000002 mounted on /dev/nst3, write enabled



"mminfo -q inuse" will tell you what is currently going on. For example,
"mminfo -q inuse -r 'volume,%used,client,level,written,name'" will show
something like:

 volume          (%) client      lvl written name
tape.004        0.1% backup.home incr 53 MB /boot
tape.004        0.1% backup.home incr 53 MB /dev/pts
tape.004        0.1% backup.home full 53 MB index:nomad-eth
tape.004        0.1% nutbuster  incr  53 MB /
tape.004        0.1% nutbuster  incr  53 MB /share/.md0


tape.004 you'll see is in use, and is mounted on /dev/nts1 (see output
from first command).

Hope that helps,
Roy
