RAID Controller Batteries
Some RAID controllers have batteries. If the controller has a battery, Storage
Management displays the battery under the controller object in the tree view.
In the event of a power outage, the controller battery preserves data that is in
the volatile cache memory (SRAM) but not yet written to disk. The battery is
designed to provide a minimum of 24 hours back up.
When a RAID controller is first installed in a server, the battery may need
charging.
For more information on Alert Messages, see the Server Administrator
Messages References Guide.
