Media Freeze

Hello Experts,

Two media are frozen and i could see logs as it contains tar-format data and cannot be used for backups in netbackup.

I could see its size as 0 kilobites.

Pls let me know what can be done to reuse the tapes.

Thanks,

  • Someone has used the tape to write backups with OS tar command.
    So, tape has not been used by NBU, but by OS Admin. That is why NBU says 0 Kb. No info in NBU about this backup.
    When tape is loaded, NBU sees the OS tar header and freezes the tape.
    This is normal behaviour when NBU sees non-NBU header on a tape.

    To see what is on the tape before you unfreeze and overwrite it in NBU, you can load the tape into a drive and the use OS command to list tape content.
    e.g. if tape is loaded in /dev/rmt/0,
    # tar tvf /dev/rmt/0

    To reuse it in NBU, go to Host Properties -> Media Server -> select media server name > Media -> Allow Media Overwrite
    Select 'tar' format.

    Unfreeze the tape.

    NBU can now overwrite data on this tape.
