If the mechanism is jammed mt(1) may not help:
mt -f tape-device offl

Can you get fuser or lsof to tell you who's
using the device? (You might need to check
all the related devices, too.)

Hi

try this

#mt â t /dev/rmt/Xmn offl

If the front panel button does not work, the mt comand will not work either (as you have seen). Hold down the eject button for more than 30 seconds. If this does not work, the tape has become tangled inside and cannot be repaired in the field (tolerances are too tight) so you'll need HP service to replace the drive.

Hi,
If your drive path is /dev/rmt/0mn
then give

#mt off

it is in different path then

#mt /dev/rmt/1mn off

This likely indicates a hardware problem with the drive. Try to power cycle the tape drive and try again.

This may not solve the problem, but likely you are able to eject the tape.

How would bad hardware cause "Device busy"?

> Hold down the eject button [...]

Might this not depend on the type of tape
drive? Has anyone said which kind of tape
drive this is?

Another process (a backup) could hang and never come back ... this can keep the device "busy".

Check with fuser.
