10.4 OST Configuration
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 244 ).
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).
