Note: After you add an LSU that uses the Available Capacity
option, you cannot change the LSU to use the Specific
Capacity option. Instead, you must delete the LSU,
then add a new LSU and choose the Specific Capacity
option (see Deleting an LSU on page 279).

• LSU Name - Enter the name of the LSU.

remote LSU on another DXi.
Automatic Image Replication (AIR) is disabled by default. If enabled,
data on an LSU is automatically replicated to a remote LSU that
resides on a DXi in a different NetBackup domain. The timing of the
duplication, as well as the backup images that are duplicated, are
