To create a storage unit group

1. In the NetBackup Administration Console, expand NetBackup Management > Storage.

2. Right-click Storage Unit Groups and select New Storage Unit Group.

3. Enter a storage unit group name for the new storage unit group.

   The storage unit group name is case sensitive.

4. Add to or remove storage units from the group:

   • To add storage units to the group, select the storage units from the Storage units not in the group list. Click Add.

   • To remove storage units from the group, select the storage units from the Storage units in group list. Click Remove.

   • Storage units are listed in order of priority: The units at the top of the list have the highest priority in the group. To change the priority of a storage unit, select the storage unit and click Move Up or Move Down.

   Note:

   OpenStorage, SnapVault, NearStore, and PureDisk storage units cannot be included in storage unit groups.

5. Choose how storage units are to be selected within the group:

   • Prioritized. Choose the first storage unit in the list that is not busy, down, or out of media.

     See Prioritized storage unit selection.

   • Failover. Choose the first storage unit in the list that is not down or out of media.

     See Failover storage unit selection.

   • Round Robin. Choose the least recently selected storage unit in the list.

     See Round robin storage unit selection.

   • Media server load balancing.

     Symantec recommends the Media server load Balancing criteria for disk staging storage units within a storage unit group.

     See Media server load balancing storage unit selection.

   One exception to the selection criteria is in the case of a client that is also a media server with locally connected storage units.

   See Exception to the storage unit selection criteria.
