## Verify DIMM Functionality

1. Access the Oracle ILOM `->` prompt.

   Refer to the SPARC T3 Series Servers Administration Guide for instructions.

2. Use the `show faulty` command to determine how to clear the fault.

   - If `show faulty` indicates a POST-detected the fault go to Step 3.

   - If `show faulty` output displays a UUID, which indicates a host-detected fault, skip Step 3 and go directly to Step 4.

3. 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 SP is power cycled. In those cases, the fault is automatically cleared from the system. If `show faulty` still displays the fault, the `set` command will clear it.

       -> set /SYS/MB/CMP0/BR0/CH0/D0 component_state=Enabled

4. For a host-detected fault, perform the following steps to verify the new DIMM:
   1. Set the virtual keyswitch to `diag` so that POST will run in Service mode.

          -> set /SYS/keyswitch_state=Diag
          Set ‘keyswitch_state' to ‘Diag'

   2. Power cycle the system.

          -> stop /SYS
          Are you sure you want to stop /SYS (y/n)? y
          Stopping /SYS
          -> start /SYS
          Are you sure you want to start /SYS (y/n)? y
          Starting /SYS

      Note - Use the `show /HOST` command to determine when the host has been powered off. The console will display `status=Powered Off`. Allow approximately one minute before running this command.

   3. 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
          .
          .
          .
          0:7:2>INFO:
          0:7:2>    POST Passed all devices.
          0:7:2>POST:    Return to VBSC.
          0:7:2>Master set ACK for vbsc runpost command and spin...

      Note - The system might boot automatically at this point. If so, go directly to Step e. If it remains at the `ok` prompt go to Step d.

   4. If the system remains at the ok prompt, type `boot`.
   5. Return the virtual keyswitch to Normal mode.

          -> set /SYS keyswitch_state=Normal
          Set ‘ketswitch_state' to ‘Normal'

   6. Switch to the system console and type the Oracle Solaris OS `fmadm faulty` command.

          # fmadm faulty

      If any faults are reported, refer to the diagnostics instructions described in Oracle ILOM Troubleshooting Overview.

5. Switch to the Oracle ILOM command shell.
6. Run the `show faulty` command.

       -> show faulty
       Target              | Property               | Value
       --------------------+------------------------+-------------------------------
       /SP/faultmgmt/0     | fru                    | /SYS/MB/CMP0/B0B0/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 `show faulty` command reports a fault with a UUID go on to Step 7. If `show faulty` does not report a fault with a UUID, you are done with the verification process.

7. 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
