Enable and Verify a DIMM
■
If the output displays a UUID, which indicates a host-detected fault, go
directly to step 3.
2.
Use the
set
command to enable the DIMM that was disabled by POST.
In most cases, replacement of a faulty DIMM is detected when the SPM is power cycled. In
those cases, the fault is automatically cleared from the server. If
show faulty
still displays the
fault, the
set
command clears it.
-> set /SYS/MB/CM0/CMP/MR0/BOB1/CH0/DIMM clear_fault_action=true
Are you sure you want to clear /SYS/MB/CM0/CMP/MR0/BOB1/CH0/DIMM (y/n)? y
Set 'clear_fault_action' to ‘true’
3. For a host-detected fault, perform the following steps to verify the new DIMM.
a.
Set the virtual keyswitch to
diag
so that POST runs in Service mode.
-> set /HOST keyswitch_state=Diag
Set 'keyswitch_state' to 'Diag'
b. Stop the host.
-> stop /System
Are you sure you want to stop /System (y/n)? y
Stopping /System
c.
Check if the host has been powered off.
Allow approximately one minute before performing this step. Type the
show /HOST
command. When the host is powered off, the console displays
status=Powered Off
.
d. Start the host.
-> start /System
Are you sure you want to start /System (y/n)? y
Starting /System
e. Switch to the system console to view POST output.
Watch the POST output for possible fault messages. The following output indicates that
POST did not detect any faults:
-> start /HOST/console
...
0:0:0>INFO:
0:0:0> POST Passed all devices.
