ignite tape failure?

Todd McDaniel_1 — Wed, 13 Aug 2008 14:17:11 GMT

Guys,

My make_tape_recovery appears to complete successfully but fails on the rewind at the end...

Does that mean my backup failed? See below...

Hi Todd:

I would definitely not consider this a success:

pax: /dev/rmt/3mn : Device busy
ERROR: Failed to open tape device /dev/rmt/3mn:Device busy (errno = 16).
ERROR: The rewind command failed.
make_tape_recovery completed unsuccessfully

Your tape drive may need to be cleaned. Your tape may be bad too. I would test your drive with a simple 'tar' and 'mt rew'.

Regards!

My first guess would be a bad/faulty tape drive.

Test the daylights out of it then replace or correct the error.

Would have expected an IO error vs device busy though, but you never know.

Is it maybe because you're using the no rewind device?

/dev/rmt/3mn is a no rewind device, try the process again using /dev/rmt/3m and let us know what happened.

I am having the drive cleaned and I took out the rewind at the end.

I will run another job today and see what it does this time.

thanks all for your help.

Hi (again) Todd:

A no-rewind device is what an Ignite 'make_tape_recovery' needs.

oh yes, but for some reason they had it using Xmn, but also with a rew option, very odd.

Now, I am using 3mn (no 0mn device)and no option to rewind.

JRF - OK, but wouldn't a rewind command on a no rewind interface always fail? I'm just asking...

Shalom,

Clean the drive, use new media and leave the rewind settings the way they were in your backup script.

" OK, but wouldn't a rewind command on a no rewind interface always fail? I'm just asking..."

nope...means that the device doesn't *automatically* rewind

you can test this with the "mt" command...

tar something to /dev/rmt/Xmn (for whatever device you have).

then issue: "mt -f /dev/rmt/Xmn rew"

okay the clean tape did its job...

Now it only had one warning I need to check into.

Hi (again) Todd:

> okay the clean tape did its job...

You will note that that was my *original* suggestion in my *first* post, too.

Hi,
If problem is with only rewind, then it mean backup is restored with error.
