When the hard disk drives are in a RAID System configuration, you can restore the state before an 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 Access LED and DISK Error LED flash
alternatively to indicate it.
IMPORTANT:
install the hard disk drive again to restart the auto-rebuild.
Observe the following notes for the auto-rebuild.
Do not power off the server in the period between a hard disk drive error and the completion of the
auto-rebuild.
Wait at least 60 seconds between the removal of a failed hard disk drive and the installation of a new one.
Do not replace another hard disk drive while a rebuilding is in progress. (The DISK Access LED and DISK
Error LED flash alternatively while rebuilding the hard disk drive.)
DISK LEDs
When the auto-rebuild fails, the DISK LED lights in amber. Remove and
