Step Action
1
Determine if the primary or optional second disk drive is to be replaced.

X
M System Administration manual , Shutting down HP-UX (Section 3.5).
4
Perform an A
X
M node processor shutdown from the LCN AM Status display.
5
Perform a second A
X
M node processor shutdown from the LCN AM Status display.
This makes the shutdown node appear as failed and prevents the rest of the LCN
nodes from labeling it isolated.
6
Turn off power, using the switch on the A
X
M node power supply after the yellow
indicator on the WSI2 board turns off.
7
Disconnect the SCSI interface cable from the coprocessor free edge. (It runs between
the WSI2 and the drive tray above it.) It requires removal of two Phillips screws
securing the cable strain relief bracket.
8
Remove the drive tray.
9
Remove the tray cover by removing three Phillips screws and eight lock nuts.
10
Remove the power connector from the drive to be replaced.
11
Remove the SCSI ribbon connector from the drive to be replaced.
12
Remove the desired disk drive by removing 4 large drive mounting screws.
13
Ensure the replacement drive is pinned correctly.
14
Mount the replacement disk drive using the same hardware that held the original drive.
15
Reconnect the drive cables removed in steps 5 and 6.
16
Replace the drive tray cover removed in step 4.
Be sure none of the cables are pinched between the cover and the tray at any point.
Failing to do so can cause damage to the cable.
17
Insert the drive tray into the chassis.
18
Reconnect the SCSI cable disconnected in step 2.
19
The node is ready for power on and loading. Turn on the power switch located on the
