How to chech if a tape is loaded into drive? 2

[trifo]

Hi!

I am trying to detect if the tape is present in the drive or not. It would be necessary for a backup script. On solaris "mt status" command gives this information, but in AIX it does not. What else does?

Normally I would just :

dd if=/dev/rmt0 of=/dev/null bs=512 count=1

and check the exit code - 1 or 0.

tctl rewind /dev/rmt0 2> /dev/null
if [ $? = 0 ];then
echo "MAG TAPE IS PRESENT"
else
echo "NO MAG TAPE IN TAPE DRIVE"
fi

How about using tapechk, just try to check consistency on first file.It would normal rewind and the read the files(tapechk 1 to check the first file on the tape). Just capture the exitcode thats it.
