Logical Storage Unit List
The Logical Storage Unit List displays the following information for all LSUs on the
ETERNUS CS800:
OST Service The status of the OST service. OST settings can be configured in Ready,
Stopped, or Verifying state. The OST server is available for backup only in
Ready state.
LSU Name The name of the LSU.
Storage
Server
The storage server that contains the LSU.
Physical
Capacity
The physical storage capacity of the LSU.
Automatic
Image
Replication
The status of Automatic Image Replication (AIR) for the LSU (Enabled or
Disabled), as well as the configured targets (if any).
To view details about the remote LSU if AIR is enabled, use the Edit
Logical Storage Unit page (see "Editing an LSU" on page 256).

Additional Information
l Click a column heading to sort the rows in the table by that column. Click the column
heading again to reverse the sort order.
l The connections of a storage server that are used equals the data streams plus one for
each LSU polling. A backup job may generate more than one data stream if the data can
be read in parallel. For example, a policy that is backing up A, B, C, and D drives of a
Windows system can generate four data streams in parallel.
Adding an LSU
Add an LSU to a storage server to present the storage capacity of the ETERNUS CS800 as
an LSU that is compatible with backup applications that support OST. You can add an LSU
with a specific capacity, or you can add an LSU that uses the available capacity of the
ETERNUS CS800.
You must create a storage server before you can add an LSU (see "Adding a
Storage Server" on page 246).
