9-16 Upgrading Your Server
6.
To use the server with the hard disk drive removed, insert a dummy tray into the empty
slot.
IMPORTANT:
dummy tray in the vacant slot of the disk bay.
7.
Close the door opened in step 2 securely.
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 drive 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 drive (or disk
replacement in the power-on state). During the auto rebuild, the disk lamp on the hard disk drive is
lit green or amber alternatively.
IMPORTANT:
If the auto rebuild fails, the disk lamp on the hard disk drive 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 drive 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 drive to
the end of the auto rebuild.
Install a new hard disk drive after the interval of 90 seconds or longer has passed from the
removal of the defected hard disk drive.
If a hard disk drive is being rebuilt, do not replace another disk. (The disk lamp on the
hard disk being rebuilt is lit green or amber alternatively.)
