Hard Disk Drive Led - NEC Express5800/120Rh-1 User Manual

Hard Disk Drive LED

The disk LED located on the drive carrier indicates the following depending on the status:
Hard disk drive
Drive carrier
3.5-inch hard disk drive
Flashing (green)
The LED indicates that the hard disk drive is 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.
