Hard Disk Drive Led - NEC Express5800/120Rg-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 disk array configuration.
NOTE: Even if one of the hard disk drives fails in disk array
configuration (RAID1 or RAID5), the server can continue operation.
However, replace the disk as soon as possible, and perform
reconstruction (rebuild) processing. (The failing disk 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 disk array configuration, 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.
