1.16.3 Replacing a hard disk drive in the RAID system
In the RAID system, you can use the auto rebuild feature to restore the data back to the state before the
failure.
The auto rebuild feature is enabled in logical drives set to RAID 1, RAID 5, RAID 6, RAID 10, RAID 50 and
RAID 60.
The disk is automatically rebuilt when hot swapping a failed hard disk drive.
During the auto rebuild, the DISK LED on the hard disk drive flashes green and amber alternately to indicate
that auto rebuild is being performed.
Observe the following precautions whenever executing the auto rebuild
•
Do not turn off the server until the auto rebuild completes.
•
Leave an interval of at least 90 seconds between a hard disk drive removal and a hard disk drive
installation.
•
Do not replace another disk during the auto rebuilding.
