Figure 4-25. Removing a Hard Disk Drive
6.
If not replacing the hard disk removed, insert a dummy carrier tray into the
empty slot.
IMPORTANT
:
To maintain the cooling effect in the server, install the
dummy tray in the vacant slot of the disk bay.
7.
Close the bezel opened in step 2 securely.
Auto Rebuild Functionality
If your server includes a disk array controller, the auto rebuild function can be
used to restore data from the defective hard disk drive. The auto rebuild
function can write the data saved from a defective hard disk to the replacement
disk drive thereby recovering 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 defective
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
:
Do not turn off the power of the server in
the interval between a fault of a hard disk to the end of the
auto rebuild process.
Wait at least 90 seconds from the time you remove a
defective disk drive to the time you install the replacement
disk drive.
If a hard disk is rebuilding, do not replace another disk. (The
disk lamp on the hard disk being rebuilt is lit green or amber
alternatively.)
