If you add disk volumes to the storage appliance, NetBackup does not add those volumes to an OpenStorage disk pool automatically. To use the additional disk volumes in an existing disk pool, you must add those volumes to the disk pool.

(By default, NetBackup automatically increases disk pool capacity if the capacity of the underlying disk volumes increases. Similarly, NetBackup decreases the capacity of a disk pool if the underlying disk volume capacity decreases.)

The NetBackup storage units that use the disk pool automatically use the additional storage capacity. You do not have to change the storage units.
