Hi at all,

I have thinked that media are consumed and so I have changed all media. But the media that go in frozen state is new...

Are you using the same drive when this error occurs?

Is the Drive in a DOWN state?

If it is do you have to bring it UP?

Is this a new drive?

If not how old is it?

Have you cleaned the drive?

Have you tryed the backup job on another drive?

oh yeah if you ant to use the tapes that were FROZEN by the bad tape drive you can un-freeze by running this.

#unfreEzzz em
/usr/openv/netbackup/bin/admincmd/bpmedia -ev $TAPE_NAME -unfreeze

MTWEOF - write end of file record

1) Check your drive firmware to see if it is compatible to VERITAS
2) Try to use VERITAS drivers. If you are using the VERITAS driver and it causes you this issue now, change it to the manufacturer driver.
3) Clean your drive

Not to beat a dead horse, but I would run a cleaning job on it and then if it still fails with the same error on multiple media, then call the manufacturer and replace the drive.
