Hard-Drive Indicator Codes
The hard-drive carriers have two indicators—a drive-activity indicator and a drive-status indicator. See
Figure 1-2.
Figure 1-2. Hard-Drive Indicators
Table 1-3 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.
