while NetBackup was writing to removable media

If the media is tape, check for:

A defective or dirty drive, in which case, clean it or have it repaired (refer to the tpclean command for robotic drives).

Defective media. If this is the case, use the bpmedia command to set the volume to the FROZEN state so it
is not used for future backups.
