Creating and Changing Storage Unit Groups

Storage unit groups allow you to identify specific storage devices as a group. A storage unit group name can be specified in a policy, just as individual storage units can be specified. When a storage unit group is used in a policy, only the storage units specified in the group will be candidates for the backup.

NetBackup uses the first storage unit listed if the storage unit is available. If the first one is not available, NetBackup attempts to use the second storage unit listed, and so on down the list.

The only exception is in the case of a client that is also a media server with locally connected storage units. The locally available storage units take precedence over the defined sequence of storage unit groups.

You may have set up a storage unit to be On Demand Only. If the storage unit is part of a storage unit group that is needed by a policy, the On Demand Only option is satisfied and the device will be used. See Policy Storage Unit.

  To create a storage unit group

1. In the NetBackup Administration Console, expand NetBackup Management > Storage Units.
2. Right-click Storage Unit Groups and select New. The New Storage Unit Group dialog appears.
3. Enter a storage unit group name for the new storage unit group.

   Use alphabetic (ASCII A-Z a-z), numeric (0-9), plus (+), minus (-), underscore(_), or period (.) characters.

   Do not use a minus as the first character or leave any spaces between characters.

     Note    The storage unit group name is case-sensitive.

4. Add to or remove storage units from the group:
   1. To add storage units to the group, select the storage units from the Storage units not in the group list. Click Add.
   2. To remove storage units from the group, select the storage units from the Storage units in group list. Click Remove.
   3. Storage units are listed in order of priority: The units at the top of the list having the highest priority in the group. To change the priority of a storage unit, select the storage unit and click Increase Priority or Decrease Priority.
5. Click OK.
