About WORM media and the Quantum drive

When you use the Quantum drive, only one kind of media can be used as either standard media or WORM media.

If a WORM volume pool runs out of media, media are moved from the scratch volume pool into the WORM pool. NetBackup determines whether the media are configured as standard or WORM media. For a standard media volume, NetBackup reads the tape label and verifies that the media is unused or that all images are expired. NetBackup also verifies that the media is not currently assigned to a server. After verification, NetBackup configures the media as WORM media and continues with the NetBackup job.
