Hi all
I'm using AIX 4.3.3 and I have a tape error in rmt1.
LABEL:          TAPE_ERR1

Date/Time:       Fri Mar 14 14:00:06
Sequence Number: 495
Machine Id:      000000000000
Node Id:         xxxxx
Class:           H
Type:            PERM
Resource Name:   rmt1
Resource Class:  tape
Resource Type:   4mm4gb

When I backup a small number of files, it will give no error. If I backup a lot of
files, it will give me some backup error.

backup: 0511-432 A write error occurred: The media surface is damaged.
backup: 0511-079 The backup media may be damaged.
        Use a different disk to run the backup.  

Although it looks like a media error, but I've change media and clean the tape drive.
Could it be the physical drive problem? Anyone out there encountered this before?

Note: I do not have maintenance contract with IBM.

Make sure you are using the right tapes. Make sure that the cleaning cartridge is not used up.  If external tape drive make sure all cables are firmly attached.  Do you log backups always fail at the same place (same file)?  If so it could be the file that is being backed up is corrupted in a fashion that the tape drive is misinterpreting the data and errors out.  If that all checks out and you know your AIX well enough you could try logically removing the tape device from your system then run the configuration manager to let the system find the tape drive and logically re-add the tape drive.  Have found that sometimes the ODM gets a little messed up and by removing the offending device then re-adding will take care of the inconsistency.  However if you are not very well versed in AIX this would be best left to someone who knows it better.  If removing and re-adding the tape device does not correct the problem then it may be time to have the tape drive serviced.

Good Luck.
