You can only have one process controlling a particular tape drive at any one time. If you have physical access to the actual drive, then press the eject button on the drive.

Hi Lukasz,

Try holding the eject button on the tape drive for 5 - 10 seconds to see if that forces ejection. If that doesn't work & it's in an external enclosure, you can try power cycling the tape drive & repeating the ejection attempt.

Rgds,
Jeff

ps -ef | grep process name

kill -9 process number from prior output.

You should never have to power cycle a working drive to regain use of the drive.

You might wish to try looking at the process to see why its hanging.

There is a tar patch that fixes a lot of bugs and lets you tar 8 Gig files.

PHCO_24633 for 11.00
PHCO_24623 for 11.11

Good luck.

Hi,
neither of solutions suggested above seemed to work. Killing of the process was not possible since it seem to hang during some I/O operation although it was possible to remove a tape from the drive (with eject button). Finally I had to restart the system.

Thanks anyway,

Lukasz

Kill won't affect a process that's waiting for I/O completion. The ONLY way around it is to re-boot.
