I backup the disk by the unix command ufsdump.
Then I abort the backup process by pressing <Ctrl> <C>.
This message appears:
DUMP: NEEDS ATTENTION: Do you want to abort dump?: ("yes" or "no")

I entered "yes".
Then tape drive is busy:

# mt -f /dev/rmt/0cn status
/dev/rmt/0cn: Device busy

Is there a unix command make the tape device not busy?

Hi! Excitement!

Try kill -15 next time to see if it makes a difference.
What is the output of 'uname -a' on your system?

Reboot.

Well, you did ask. ;-)

Did you wait for a period of time before checking the status? Tape
drives can take minutes to rewind/release their SCSI status...

Failing that, start with the usual ps/fuser/lsof to check for anything
holding the drive open.

Oh come on "AM" - at least you could have suggested "uadmin 2 0": that
way he would have required console-ish access to reboot a system that
might be corrupted. You're slipping ;^)

TCMa: please don't try with/without a SUN support contract...

Run 'fuser /dev/rmt/0cn' and see if it's open by a process.

If you examine the headers closely you'll notice that that post
wasn't one of mine but one by Plugger the putz (AKA Cypherpunk)
doing his usual sock puppetry. Who else but he and Don Kook
would be stupid enough to suggest a reboot? Perhaps Josh What's-
His-Name but Plugger is so dumb he has to log in as root because
the pathetic little script kiddie doesn't know how to create user
accounts yet. He even thinks a ^W is a vi command. How dumb is that?

try typing

mt -f /dev/rmt/? rewoff

Assuming you are using an external tape (a single tape, not a Robot)
turn off the drive
turn it on again AND press the eject button of the tape, hold the eject
button down until the tape exits the drive.

Mount the tape again and start your backup.

The message comes because there still is a process waiting on the drive
to finish its current operation.

Use
smt -f /dev/rmt/0cn -wready status

Repeat, if it does abort after 120 seconds and the drive is not yet ready.
Note that smt understands the remote tape syntax used by ufsdump and star.

"smt" is part of the "star" package:
