continue operation. However, replace the hard disk drive as
soon as possible, and perform a reconstruction (rebuild)
processing. (The failing hard disk drive can be hot-swapped.)
■ Flashing switching back and forth between green and amber
The lamp 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 a RAID system, the system rebuilds the data. (Auto-rebuild function)
The lamp switches back and forth between green and amber during rebuild
processing.
The lamp goes off when the rebuild processing finishes.
It turns amber when the rebuild processing fails.
If the server is turned off during rebuild processing, the process-
ing is stopped. Restart the server, mount the new hard disk in
hot swap mode, and then perform rebuild processing again.
Observe the following notes on using the auto-rebuild function.
