Hard Disk Lamp
The disk lamp mounted in the 3.5-inch device bay indicates the following, depending on the
status:
!
Flashing (green)
The lamp indicates that the hard disk is being accessed.
!
On (amber)
The lamp indicates a failure of a hard disk mounted in disk array configuration.
NOTE:
Even if one of the hard disks fails in disk array configuration
(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 completed. It turns a steady amber if
the rebuild processing fails.
