Tested on HPUX 11.00

No tape in unit.
# mt -t /dev/rmt/1m rew
/dev/rmt/1m: No such device or address
# echo $?
1

Tape in unit
#
# mt -t /dev/rmt/1m rew
# echo $?
0

If you use the command mt -t /dev/rmt/devfile >/dev/null 2>& then you won't
get the error message, but the status is still set.  Of course, this only
works if you want the tape at the BOF.

        Unfortunately the mt command on HP-UX does not have a status option
( it
        does on Solaris ),
        look at the man page for mt.   you could experiment with some of the
        available options, say
        rew or fsr which will probably give an I/O error if there is no tape
in the
        drive.   ioscan only tells
        you that the tape drive is configured.

                E.G. mt  -t   /dev/rmt/0mnb  rew

         ( where  0mnb is the tape device you are interested in ).
