10-6 TroubleshootingHard Disk Drive LEDThe hard disk drive bay can contain three hard disk drives. Each hot-plug hard disk drive has aDISK LED on its front panel.The DISK LED indicates the drive status as follows. Blinking greenIndicates that the hard disk drive is accessed. Lighting amberIndicates that the installed hard disk drive is defected.NOTE: While hard disk drives are in the RAID configuration (RAID1,5, or 6), a single failed hard disk drive does not affect the operation ofthe server. However, it is recommended to replace the failed hard diskdrive and auto-rebuild (reconfigure) the hard disk drives as soon aspossible. (You can hot-swap such a failed hard disk drive.) Alternate blinking amber or greenIndicates that the hard disk drive is being rebuilt (this status is not a failure). If thedefected hard disk drive is replaced with a new one in the RAID configuration, the data isautomatically rebuilt (auto rebuild function).The LED goes off when the rebuild is terminated normally. The LED goes on amber if therebuild fails.IMPORTANT: Powering off the server aborts rebuilding. In such acase, restart the server, hot-swap the failed hard disk drive, and restartrebuilding. Observe the following notes to use the auto-rebuild feature. Do not power off the server. (If the server is powered off beforerebuilding hard disk drives, the auto-rebuild feature will not start.) When you removed a hard disk drive, wait at least 90 secondsbefore installing the hard disk drive back again. Do not replace another hard disk drive while rebuilding is inprogress.DISK LED DISK LED3.5-inch hard disk drive 2.5-inch hard disk drive
