9-16 Upgrading Your Server

In the disk array configuration, the auto rebuild function can be used. The auto rebuild function

can record the information saved in a defected hard disk into the new replaced disk to recover the

server to the state before the occurrence of the fault.

The auto rebuild function is valid for disk arrays set to RAID1 or RAID5.

The auto rebuild is automatically started only by the hot-swap of a defected hard disk (or disk

replacement in the power-on state). During the auto rebuild, the disk lamp on the hard disk is lit

green or amber alternatively.

IMPORTANT:

 If the auto rebuild fails, the disk lamp on the hard disk goes on

amber. Provide the disk removal or installation again to run the

auto rebuild.

 If the disk array monitoring utility is installed, the following display

or operation may occur. However, the auto rebuild is conducted

correctly if the disk lamp of the hard disk subject to the auto rebuild

is not lit amber after the termination of the auto rebuild.

– Message "Rebuild was canceled" appears on the screen during

the auto rebuild.

– It seems that the auto rebuild is terminated once and then

restarted.

Obey the following cautions when the auto rebuild function is used.

 Do not turn off the power of the server in the interval from a fault of a hard disk to the end

of the auto rebuild.

 Install a new hard disk after the interval of 90 seconds or longer has passed from the

removal of the defected hard disk.

 If a hard disk is being rebuilt, do not replace another disk. (The disk lamp on the hard

disk being rebuilt is lit green or amber alternatively.)
