Hard Disk Lamp
The disk lamp mounted in the 3.5-inch disk bay indicates the following depending on the
status:
Flashing (green)
The lamp indicates that the hard disk is accessed.
On (amber)
The lamp indicates a failure of a hard disk mounted in disk array configuration.
Even if one of the hard disks fails in disk array configuration
NOTE:
(RAID1, RAID5, or RAID0+1), 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 lamp indicates that reconstruction (rebuild) processing is being performed for the
hard disk. (This flashing does not indicate a failure.) When a failing hard disk is
replaced in disk array configuration, the system automatically rebuilds the data.
(Auto-rebuild function) The lamp switches back and forth between green and amber
during rebuild processing.
The lamp goes off when the rebuild processing has terminated. It turns amber when
the rebuild processing fails.
