Hard-Drive Indicator Codes
If an optional SAS backplane is installed in the system, two indicators on each of the hard-drive carriers provide information on the status of the hard drives.
See Figure1-4 and Table1-5.TheSASbackplanefirmwarecontrolsthedrivepower-on/fault indicator.
Figure 1-4. Hard-Drive Indicators
Table1-5 lists the drive indicator patterns. 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.
