We're going to reboot the machine in approx. 30 hour, but I'd appreciate
any insights on how I can free up a device without rebooting.
Thanks,

tape unload

This particular problem is what causes 90% of our reboots. I'm not sure
what SCO does with it's tape drivers but all I (or one of our operators)
need to do is issue a dd command to copy in from tape before the tape is
ready and we get this message. From then on, the drive cannot be accessed
until we reboot.
...or, if we have a tape with errors, it seems SCO OSR5.0.5 just doesn't
handle the errors correctly.
Does anyone else run into this problem?

Ken,
Now that all my customers have converted to DAT tape drives, this problem
(can't eject tapes) has cropped up at several sites. Occasionally it happens
only once - they reboot and have no more problems. What caused it? Who knows.
In several other cases it was traced to a single tape. Throw out that tape &
it does not happen any more. In other cases, the tape drive was replaced & the
problem went away.
I wonder if the DAT tapes, specially DDS-3, are less robust than than the
DC-6525, etc.

Yup.

I had a customer who called the HW vendor because they were sure
the DAT drive had failed. I was called to be on hand during
warranty replacement.
A month later they called - it had happened again. A quick ps -ef
showed that a program still had the drive open. Kill the program,
and the DAT could then eject. That's the nature of the beast - it
is designed not to let you eject a tape if it is in use.

Well, sorta. HP drives have a not-so-secret method of ejecting the tape
when busy. Punch the button 3 times, wait 45 seconds, and out it comes.
It's somewhere in the C1533A and C1537 manuals.

Certainly true, but defective equipment and misconfiguration
can also do this. For example, I've seen a DAT configured
as Generic- it would not eject. I also had a customer
with a DAT tape that would not eject after being used
without rebooting, but I couldn't find any reason for it, so
we replaced it. I took the unit to another machine (same OS
and
version), and there it would eject fine, but then you
couldn't put a new tape (it just would not load) in without
rebooting, so the drive still wasn't very useful :-)
