Hmm.. Did you try issuing a "mt -f /dev/st0 offline" before unloading the
tape?  My Dell powervault gear (which is older than yours I'm sure, but
still probably rebadged ADIC gear) require the tape drive to be taken
offline and the tape ejected before the changer can move the tape back
into the slot.  Is your the same?

Try this using the RHEL kernel:
# insert any mt commands to set the blocksize here
mtx -f /dev/sg0 load 1
tar -cpvf /dev/st0 /var # Add blocksize as needed
mtx -f /dev/sg0 unload

If that yeilds the same error (or simialr from mtx) try adding the
following command after the tar:
	mt -f /dev/st0 offline
(Note: you want to do this on a tape that doesn't have data on it already
:)

If that works, most likely everything else should too and it's a matter of
making the software do the right thing at the right time.

HTH,
