3.3.3.7 Battery Backup Submenu Description
Select this option from the Configuration Utility Objects menu to display
information about the battery backup.
Table 3.8 lists and describes the
options for the Battery Backup submenu. This option is available only on
controllers that support the battery back-up feature.
Note: If the battery is not present on the board, the battery
options do not display.
3.3.4 Clear Option
Select the Clear option from the Configuration Utility Management Menu
to clear data on one or more physical drives.
You do not have to select Clear to erase existing information on your
disks, such as a system partition. Initialization of the logical drives erases
all the information on the drive.
3.3.5 Rebuild Option
Select this option to rebuild failed disk drives. If a disk drive fails that is
in a RAID 1, 5, 10, or 50 configuration, you can recover the lost data by
rebuilding the drive. The CU can perform an automatic rebuild if hot spare
disks are available in the system. If no hot spare disks are available, the
data must be manually rebuilt. Refer to
Section 3.8, “Rebuilding Failed
Disks,” on page 3-30 for the procedure on rebuilding disks.
