10.4 OST Configuration
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 242).
Active Connections The number of currently active connections to the LSU.
Backup Images The number of backup images on the LSU.
Description A brief description of the LSU (if available).
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 232).
