Hard-Drive Indicator Codes
The hard-drive carriers have two indicators—the drive-activity indicator and the drive-status indicator. See Figure1-2. In RAID configurations, the drive-status
indicator lights to indicate the status of the drive. In non-RAID configurations, only the drive-activity indicator lights; the drive-status indicator is off.
Figure 1-2. Hard-Drive Indicators
Table1-3 lists the drive indicator patterns for RAID hard drives. Different patterns are displayed as drive events occur in the system. For example, if a hard
drive fails, the "drive failed" pattern appears. After the drive is selected for removal, the "drive being prepared for removal" pattern appears, followed by the
"drive ready for insertion or removal" pattern. After the replacement drive is installed, the "drive being prepared for operation" pattern appears, followed by
the "drive online" pattern.
