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.
If there is 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 backup of 24 hours.
When a RAID controller is first installed in a server, the battery may need charging.
For information on alert messages, see the Server Administrator Messages Reference Guide .
