Enable and Verify a DIMM

Language:

Access the Oracle ILOM prompt.

Use the show faulty command to determine how to clear the fault.
- If the output indicates a POST-detected fault, go to Step 4.
- If the output displays a UUID, which indicates a host-detected fault, go to Step 5.

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 service processor is power cycled. In those cases, the fault is automatically cleared from the server. If show faulty still displays the fault, the set command will clear it.
```
-> set /SYS/MB/CMP1/MCU0/CH1/D0 requested_config_state=Enabled
```

For a host-detected fault, perform the following steps to verify the new DIMM.
1. Set the virtual keyswitch to diag so that POST runs in Service mode.
```
-> set /HOST keyswitch_state=Diag
Set 'keyswitch_state' to 'Diag'
```
2. Power cycle the server.
```
-> stop /System
Are you sure you want to stop /System (y/n)? y
Stopping /System
-> start /System
Are you sure you want to start /System (y/n)? y
Starting /System
```
3. 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.
4. 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.
0:0:0>POST:    Return to VBSC.
0:0:0>Master set ACK for vbsc runpost command and spin...
```
  Note - The server might boot automatically at this point. If so, go directly to Step 6. If the server remains at the OpenBoot prompt (ok) go to the next step.
5. If the server remains at the OpenBoot prompt, type boot.
6. Return the virtual keyswitch to Normal mode.
```
-> set /HOST keyswitch_state=Normal
Set 'keyswitch_state' to 'Normal'
```
7. Switch to the system console and type the Oracle Solaris fmadm faulty command.
```
# fmadm faulty
```
  If any faults are reported, refer to the diagnostics instructions described in Identify Faulted Components.

Switch to the Oracle ILOM command shell.

Type:

-> show faulty
Target              | Property               | Value
--------------------+------------------------+-------------------------------
/SP/faultmgmt/0     | fru                    | /SYS/MB/CMP1/MCU0/CH1/D0
/SP/faultmgmt/0     | timestamp              | Dec 14 22:43:59
/SP/faultmgmt/0/    | sunw-msg-id            | SUN4V-8000-DX
faults/0            |                        |
/SP/faultmgmt/0/    | uuid                   | 3aa7c854-9667-e176-efe5-e487e520
faults/0            |                        | 7a8a
/SP/faultmgmt/0/    | timestamp              | Dec 14 22:43:59 
faults/0            |                        |

If the output reports a fault with a UUID go to Step 7. If the output does not report a fault with a UUID, you are done with the verification process.

Switch to the system console and type the fmadm repair command with the UUID.
Use the same UUID that was displayed from the output of the Oracle ILOM show faulty command.
```
# fmadm repair 3aa7c854-9667-e176-efe5-e487e520
```
