Freezing media

i have set a policy to backup vm's it was working fine but since the last few days i'm getting an error that i don't have media to run the backup, when i allocate additional media then after running one successful job it tells me that i'm out of media. i have checked my media and found that after a job is run netbackup is freezing the media, unfreezing doesn’t help. could someone assist with this i'm runing netbackup 7.0.1

    a dirty drive head to a more serious h/w issue requiring replacement of the drive.

    Do you always have issues with the same drive?

    Freezing media while taking any backup's in the sense it maight be due to media write error .

    Are you able to see in the admin console , which ever the backups you are running whether its giving any media write error or not . If consequent 3 error occurs on a perticular media with in 12 hrs then the media will be freezed .

    media write errors may happen due to issue with drive , check the drives .

    You can unfreeze the media in the GUI under media. Right click on the media and select unfreeze.

    Run Tape Logs Report for the last couple of days. You will find all errors with tape media that were encountered.

    If there is al lot of info in the report, use the 'filter' option to exclude 'Info' type messages, leaving you with Warning and Error messages.

    unfreezing doesn't help, i have checked the error logs and i found out that there was a write error, but i would like to know what caused the write_error .

    Increase Media Management logging by adding VERBOSE entry to ...\veritas\volmgr\vm.conf on the media server. Restart NBU.

    Device errors will be logged in Event Viewer System and Application log.

    Also ensure that you have bptm log on the media server for further troubleshooting.

    I assume that media in frozen state contain data in format such as tar, cpio, netbackup offline catalog backup or so. Once unfreeze them and label.
