2-14 General Description

Hard Disk Drive LED

The disk LED located on the drive carrier indicates the following depending on the status:

Disk LED

3.5-inch hard disk drive 2.5-inch hard disk drive

 Flashing (green)

The LED indicates that the hard disk drive is being accessed.

 On (amber)

The LED indicates a failure of a hard disk drive mounted in RAID System.

NOTE: Even if one (two hard disk drives in RAID6) of the hard disk drives fails in Logical Drive

(RAID1, RAID5, or RAID6), the server can continue operation. However, replace the hard disk

drive as soon as possible, and perform reconstruction (rebuild) processing. (The failing hard disk

drive can be replaced in hot swap mode.)

 Flashing switching back and forth between green and amber

The LED indicates that reconstruction (rebuild) processing is being performed for the hard disk drive. (This flashing

does not indicate a failure.) When a failing hard disk drive is replaced in RAID System, the system automatically

rebuilds the data. (Auto-rebuild function) The LED switches back and forth between green and amber during rebuild

processing.

The LED goes off when the rebuild processing has terminated. It turns amber when the rebuild processing fails.
