Ignite tapes ejected when Ignite completes

Joan Blais — Tue, 13 Sep 2005 13:11:51 GMT

I have several Ignites that still run to DAT drives, HP device #C5683A.
Most eject the tape upon completion, but some do not. The Ignite scripts are set up the same:
/opt/ignite/bin/make_tape_recovery -x inc_entire=vg00 -a /dev/rmt/cXtYdZBESTn
/usr/bin/mt -t /dev/rmt/cXtYdZBESTb offline
Any way to force the tape to eject?
Thanks,
Joan

The way to force the tape to eject is to use the mt offline command - as you are doing. Are you sure it is present in all your scripts? Patch level differences? Tape drive differences? Firmware level differences?

Using the mt command with the offline option is how to make a tape eject.

The tape will reqind before offline (ejecting).
What happens if you issue rewind with the mt command? And do this before you mt-offline?

mt -t /dev/rmt/cXtYdZBESTb rewind
mt -t /dev/rmt/cXtYdZBESTb offline

Joan,

It shouldn't make any difference I wouldn't think but you're writing to the AT&T style device, then rewinding the Berkely style device. I would be tempted to try "/usr/bin/mt -t /dev/rmt/cXtYdZBESTn offline" and see if that makes any difference.

Pete, changing the b to an n worked.
Thank you

Hi Joan ,

You could try with n option as said above.

And also make rewind opetion before offile

/usr/bin/mt -t /dev/rmt/cXtYdZBESTn rew
/usr/bin/mt -t /dev/rmt/cXtYdZBESTn offl

----------------------------------------
rew Rewind tape.
offl Rewind tape and go offline.
-----------------------------------------

Cheers,

Raj.
