8.3 Fault of Disk Drive If a disk drive is defected, the SERVICE LED on the array controller is lit orange. In
addition, the SERVICE LED on the additional disk enclosure in which the defected disk
drive is installed and the FAULT LED on the defected disk drive are lit orange.
The defected disk drive may be replaced with the powers of the disk array unit and
additional disk enclosure remaining ON.
If the FAULT LED on a disk drive is lit, the fault of the other disk with the same LDN
causes the data to be lost due to interruption of redundancy. If the FAULT LED on a disk
drive is lit, replace the disk drive immediately. Perform the replacement job as quick as
possible. Do not operate the additional disk enclosure for a long time in the state that the
disk drive is pulled out.
Replace the defected disk drive with a disk drive having the same storage capacity and
same revolution.
<Replacement procedure>
(1) Confirm the defected disk drive with the FAULT LED on the disk drive being on.
(2) Pull the ejector of the defected disk drive toward you to release the lock.
When the lock is released, a click occurs.
After the lock is released, hold the handle to pull out the disk drive.
While the disk drive is pulled out, wait until the revolution of the installed hard disk
is stopped (for about 30 seconds) in the middle of the slot.
