Blinking green
!
Indicates that the hard disk is being accessed.
Lit amber

Even if one of the hard disks fails in disk array configuration
NOTE:
(RAID1 or RAID5), the server can continue operation. However, the disk
must be replaced as soon as possible, and reconstruction (rebuild)
processing must be performed. (The failing disk can be replaced in hot
swap mode.)
Flashing between green and amber
!
The LED 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 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 color when
the rebuild processing fails.
