to Chapter 3 (2. System BIOS Setup).

1.12.3 Replacing a hard disk drive in the RAID System (Auto Rebuild)

In the RAID System, you can use the auto rebuild feature to restore data back to the state before a failure
occurred.
The auto rebuild feature is enabled in logical drives set to RAID 1, RAID 5, RAID 6, or RAID 10.
The disk is automatically rebuilt when hot swapping (replacing a disk while the power on) 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 the auto rebuild is being performed.
Observe the following precautions whenever using the auto rebuild feature.

Do not turn off the server until the auto build completes after a hard disk drive fails.

Leave an interval of at least 90 seconds between a hard disk drive removal and a hard disk drive installation.

Do not replace a disk if another hard disk drive is being rebuilt (during an auto rebuild, the DISK LED on the
hard disk drive flashes green and amber alternately).
Important NEC assumes no liability for data leakage should the product be transferred to a
third party without erasing the data.
Note If you need to remove a hard disk drive due to a failure, check the slot with its DISK LED lit
in amber.
Note Do not remove the hard disk drive by pulling its handle. Doing so may damage the handle.
