As a rule, if I get any media related errors, and it is consistent with tapes recently unfrozen, then yes I dispose of them.
 
If you are seeing it taking place on the same drive, then that may be the next avenue to explore.

Our environment is HP-UX 11.11, Netbackup 5.1 MP3 backing up mostly HP Unix.

I’m cleaning up some frozen tapes and wondered what the group uses to determine if a tape should be discarded or unfrozen and put back into NetBackup.  I ran a bpmedialist –summary report and grep’d out the FROZEN tapes.  Then I looked at the /usr/openv/netbackup/db/media/errors log and matched up my frozen tapes with the errors in the log.  The errors I have are either WRITE_ERROR, POSITION_ERROR, OPEN_ERROR or READ_ERROR.  Does anyone automatically discard any tapes if they get any of these errors?  How do I know if it was an actual tape error or one caused by the drive?  I could unfreeze all the tapes, keep a closer eye on them and if it happens again get rid of the tape but I’m a little hesitant to do that right before the Holidays.  Thanks in advance, any input on this is appreciated.
