an ACTIVE status! i.e. it is available for use.
From "Help":
The status of the media. The following are messages that may appear:
Active: The volume is currently in use.
Frozen: A frozen volume is unavailable for future backups. A frozen volume never expires, even after the retention period ends for all backups on the media. The media ID is never deleted from the NetBackup media catalog, and it remains assigned to NetBackup.
A frozen volume is available for restores. If the backups have expired, you must import the backups first.
Suspended: You cannot use a suspended volume for backups until retention periods for all backups on it have expired. At that time, NetBackup deletes the suspended volume from the NetBackup media catalog and unassigns it from NetBackup.
A suspended volume is available for restores. If the backups have expired, you must import the backups first.
Full: The volume is full and nckups are written to it. NetBackup sets FULL status if it encounters an end of media (EOM) during a backup.
A full volume is unavailable for future backups until the retention period expires for all backups that are on it. At that time, the volume is deleted from the NetBackup media catalog and unassigned from NetBackup.
Multi-Retlev: (Multiple Retention Level) The volume contains backups of more than one retention level.
Imported: The backup was imported to this server. The volume cannot be used for further backups until retention periods for all backups on it have expired. At that time, the imported volume is deleted from the NetBackup media catalog and unassigned from NetBackup.
An imported volume is available for restores. If the backups have expired, you must import the backups first.
MPX_MEDIA: The media contains multiplexed images.
WORM: The volume is a WORM volume.
BE: The volume contains Backup Exec images.
***EDIT***
Not sure exactly
how accurate that is but it's close! Could add:
Active MPX - in use with multiplexed images.
Full MPX - full with multiplexed images.
