Managing volume inventory
You can manage volume inventory by controlling the server's access to volumes, by reusing tapes, and by reusing volumes that are used for database backup and export operations. You can also manage inventory by maintaining a supply of scratch volumes.
About this task
Each volume that is used by a server must have a unique name, whether the volumes are used for storage pools, or used for operations such as database backup or export. Volumes that are in different libraries but that are used by the same server must also have a unique name.
