Dell NetWorker 19.9 Administration Guide

Managing volumes

A volume is a physical piece of media such as a tape cartridge or disk. On file type devices, a volume is a directory on a file system. Volume management tasks include changing the mode or recycle policy for the volume, relabeling the volume, removing volumes from the media database and online indexes, and marking a volume as full for offsite storage.

If a volume is not mounted when a backup is started, then one of three messages appears, suggesting that one of these tasks be performed:

• Mount a volume.
• Relabel a volume (only when Auto Media Management is enabled).
• Label a new volume (only when Auto Media Management is enabled).

During file recovery, the NetWorker server requests the volume name. If multiple volumes are needed to recover the files, the server lists all the volumes in the order of which they are needed. During the recovery process, the server requests each volume, one at a time. If a library is used, the server automatically mounts volumes that are stored in the library.

To manage volumes, you must have the correct permissions that are associated with the NetWorker server and its storage nodes.
