Hard Disk Drive Lamp

The disk lamp on the 3.5-inch hard disk drive bay has different meanings depending on the display status. See Figure 5-4.

Lamp

Figure 5-4. Hard Disk Drive Lamp Location

!Lighting green

Indicates that the power is supplied to the hard disk.

!Blinking green

Indicates that the hard disk is accessed.

!Lighting amber

Indicates that the installed hard disk is defected in the disk array configuration.

NOTE: While hard disks are in the disk array configuration (RAID1 or RAID5), a single failed hard disk does not affect the operation of the server. However, it is recommended to replace the failed hard disk and auto-rebuild (reconfigure) the hard disks as soon as possible. (You can hot-swap such a failed hard disk.)

!Alternate lighting green or amber

Indicates that the hard disk is being rebuilt (this status is not a failure). If the defected hard disk is replaced with a new one in the disk array configuration, the data is automatically rebuilt (auto rebuild function). During the rebuild operation, the lamp is lit green or amber alternatively.

The lamp goes off when the rebuild is terminated normally. The lamp goes on amber if the rebuild fails.

IMPORTANT: To abort rebuilding, power off the server. In such a case, restart the server, hot-swap the failed hard disk, and restart rebuilding. Observe the following notes to use the auto-rebuild feature.

!Do not power off the server. (If the server is powered off before rebuilding hard disks, the auto-rebuild feature will not start.)

!When you removed a hard disk, wait at least 90 seconds before installing the hard disk back again.

!Do not replace another hard disk while rebuilding is in progress.
