Notes on Specifying a Storage Unit

• If your site has only one storage unit or there is no preference for storage:
• Specify Any Available for the policy storage unit and
• Do not specify a storage unit at the schedule level

However, in this instance, ensure that you do not configure all storage units to be On Demand Only, or NetBackup will be unable to find an available storage unit for the backups.

• If you designate a specific storage unit and it is not available (for example, because it is down for maintenance), backups will not run for policies and schedules that require the storage unit.
• If your NetBackup configuration has several storage units and you want a policy to use more than one but not all of the storage units, select a storage unit group that has been configured to contain the desired storage units.

Another method to restrict the storage units used by a policy is the following:

1. When configuring volumes in Media Manager, define a volume pool and volumes that are available only to the desired storage units.
2. For the policy, set Policy Volume Pool to the volume pool defined in step a.
3. For all policies, set Policy Storage Unit to Any Available.
• 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 On Demand Only.
