error using the auto-rebuild feature that stores the data in the old hard disk drive into a new one.
The auto-rebuild feature may be enabled or disabled depending on the RAID level.
Auto-rebuild is automatically carried out when you hot-swap a failed hard disk drive with a new one
(replace the disk while the server is powered). While auto-rebuild is in progress, the DISK lamp
flashes green and amber alternatively to indicate it.
IMPORTANT:
amber. Remove and install the hard disk drive again to restart auto-
