Select Volumes screen

Select the disk volumes to include in the disk pool.

AdvancedDisk

NetBackup requires exclusive use of the disk resources. If the volumes are used for purposes other than backups, NetBackup cannot manage disk pool capacity or manage storage lifecycle policies correctly. Therefore, NetBackup must be the only entity that uses the volumes.

NetBackup does not filter out common file system mount points, such as / and /usr. Therefore, carefully choose the volumes to include in a disk pool. Some operating systems use a file system paradigm to manage many types of objects. Be sure that you select the file systems or the volumes that are available for data storage.

If you have more than one AdvancedDisk storage server, be aware of the following:

  • Each media server must mount the file systems of all the disk volumes within a disk pool.

  • The mount points must be the same on each media server.

    NetBackup does not validate mount points, so you must ensure that the mount points are the same for each media server. You also must ensure that the mount points are valid.

  • To obtain a consolidated list of disk volumes, NetBackup queries every media server. For large sets of servers, queries may affect performance.

  • Disk volume status is monitored on a single media server. Which server monitors the status can change. Therefore, a change in disk volume availability on one media server may not be reflected in the disk volume status NetBackup reports.

If necessary, backup images span individual disk volumes in a disk pool. Backup images do not span across multiple disk pools.

Note:

Symantec recommends that you do not span backup images across NFS volumes in an AdvancedDisk disk pool. File system full conditions cannot be detected adequately. Therefore, a disk pool based on NFS volumes should be comprised of only one volume.

OpenStorage (VendorName)

All disk volumes available on the storage server appear.

If necessary, backup images span individual disk volumes in a disk pool. Backup images do not span across multiple disk pools.

PureDisk

For PureDisk disk pools, all disk storage is exposed as a single volume. The PureDiskVolume is a virtual name for the entire storage that is dedicated to the deduplicated backups.

NetBackup requires exclusive use of the disk resources. If the volumes are used for purposes other than backups, NetBackup cannot manage disk pool capacity or manage storage lifecycle policies correctly. Therefore, NetBackup must be the only entity that uses the volumes.
