2. Enter information about the LSU.
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.
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 258 ).
Specific
Capacity Select this option to specify the physical capacity of the LSU, and then
enter the following information.
l
LSU Name - Enter the name of the LSU.
l
Physical Capacity - Enter the physical capacity of the LSU (1 to
1048576 GB).
Fujitsu Technology Solutions recommends setting LSUs to maximum
size (1048576 GB) because spanning them on a backup is not
possible.
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 NetBackup and
Backup Exec OST Configuration Guide (6-67079).
You must configure at least one remote user before you can enable Automatic
Image Replication (see
"Manage Remote Users" on page 261 ).
