Hi

I have a dlt8000 device with a tape stuck in it: All lights on the device
are flashing. After pressing the unload button, the tape appears to be
rewind (that's according to the sound of the device) but after a while
(start of tape?) the lights all go back to flashing mode. Operating the
handle seems to crach stuff so that is to be avoided. `mt offline` reports
"device busy"

The last known action on the device is last nights backup. That once crashed
near the end of the backup so it might have hit the end of the tape. This
crashed backup is a dump of a file from a remote machine. At the machine
with the tape drive, there is a `dd` process that changes the blocksize of
this file. This process is gone hence the tape shoule be free.

In the past, I've had similar problems with old hardware and both 10.20 and
11.0. This old machine had to be rebooted to be able to eject the tape. Due
to the nature of the current problem machine, this reboot is not acceptable.

What is happening with the tape device?
How can I stop it now and eject the tape?
How can I avoid it in the future?

System at hand: L-class and N-class hardware, HP-UX 11.0, DLT tape device
Previous problem machines: D-class hardware, HP-UX 10.20 and 11.0, dds tape
device

CBee
