3. (Optional) In the Description box, enter a brief description of the LSU.
4. (Optional) Select the Enable Automatic Image Replication check box to automatically
replicate (duplicate) data on the LSU to a remote LSU on another ETERNUS CS800.
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 ETERNUS CS800 in a
different NetBackup domain. The timing of the duplication, as well as the backup
images that are duplicated, are determined by the storage lifecycle policies (SLPs)
configured in NetBackup.
OST AIR requires NetBackup 7.1 or higher. For information about configuring
NetBackup for Automatic Image Replication, see the ETERNUS CS800 OST Guide.

5. If Automatic Image Replication is enabled, select the replication target you want to
replicate images to. (You can select only a single target.) When images are replicated,
data will be sent to the selected target.
6. If Automatic Image Replication is enabled, specify the following information:
●
254
Storage Server - Select the storage server that will contain the new LSU.
Available Capacity - (Recommended for best performance) Select this option to
add an LSU that uses the available capacity on the system.
You cannot add an available capacity LSU to a storage server that already contains
an LSU. Also, if you add an available capacity LSU to a storage server, you cannot
add additional LSUs to that same storage server.
I
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
Specific Capacity - Select this option to specify the physical capacity of the LSU,
and then enter the following information.
LSU Name - Enter the name of the LSU.
●
Physical Capacity - Enter the physical capacity of the LSU (1 to 1048576 GB).

Fujitsu recommends setting LSUs to maximum size (1048576 GB)
because spanning them on a backup is not possible.
You must configure at least one remote user before you can enable Automatic
Image Replication (see
Remote Storage Server Name - The name of the remote storage server (on the
target ETERNUS CS800) to replicate data to. The source ETERNUS CS800 and
target ETERNUS CS800 must reside in different NetBackup domains.
