FIELD ENGINEER INSTRUCTIONS

PROBLEM OVERVIEW: replace a faulty SPARC T4-4 Main Module Motherboard

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? :
The server must be fully shut down and the power cords disconnected.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

Main Module Motherboard Overview

When replacing the main module motherboard, remove the service processor and System Configuration PROM from the old motherboard and install these components on the new motherboard. The service processor contains the Oracle ILOM server configuration data and the System Configuration PROM contains the server host ID and MAC address. Transferring these components will preserve the server-specific information stored on these modules.

System firmware consists of two components: a service processor component and a host component. The service processor component is located on the service processor and the host component is located on the motherboard. In order for the server to operate correctly, these two components must be compatible.

After replacing the motherboard, the host firmware on the motherboard might be incompatible with the service processor firmware on the service processor that you transferred to the new motherboard. In this case, the server firmware must be loaded as described in Install the Main Module Motherboard.

A) Remove the Main Module Motherboard

The main module motherboard is a cold-service component that can be replaced only by authorized service personnel.

1. Remove the main module from the server.

2. Make a note of the locations of the components in the main module before removing any of them.

The server software keeps track of the location of some components, such as the hard drives and RAID expansion modules, so you might have to reinstall the software on some components if they are moved to different locations in the main module. Make a note of the location of the components in the main module and install these components in the same locations in the new main module so that you do not have to reinstall software on any of these components.

3. Take the necessary ESD precautions.

4. Remove the following components from the main module:

- Remove a Hard Drive
- Remove the RAID Expansion Module
- Remove the Service Processor Card
- Remove the System Battery
- Remove the Front I/O Assembly
- Remove a Storage Backplane

5. Remove the system configuration PROM from the faulty motherboard.

NOTE: Put the system configuration PROM aside to install it on the replacement motherboard.

B) Install the Main Module Motherboard

1. Install the system configuration PROM from the old motherboard onto the replacement motherboard.

2. Replace these components on the main module:

- Install a Storage Backplane
- Install the Front I/O Assembly
- Install the System Battery
- Install the Service Processor Card
- Install the RAID Expansion Module  Note:  be sure to install the RAID Expansion Modules in the same slots as the previous Main Module.
- Install a Hard Drive

NOTE: Install the components in the same slots that you removed them from in the old main module to keep from having to reinstall software on these components.

3. Insert the main module back into the server.

4. Connect a terminal or a terminal emulator (PC or workstation) to serial management port.

If the service processor detects that the new host firmware component is incompatible with service processor firmware component, further action will be suspended and the following message will be delivered over the serial management port.

Unrecognized Chassis: This module is installed in an unknown or unsupported chassis. You must upgrade the firmware to a newer version that supports this chassis.

If you see this message, go on to Step 5.

5. Download the system firmware.

a. If needed, configure the service processor’s network port to enable the firmware image to be downloaded.
b. Download the system firmware.

Follow the related instructions in the Oracle ILOM documentation, available at the following link:
http://docs.oracle.com/cd/E19860-01/index.html

NOTE: You can load any supported system firmware version, including the firmware revision that had been installed prior to the replacement of the motherboard.

C) Verify Main Module Motherboard Functionality

1. Verify that the OK LED is lit on the main module and that the Fault LED is not lit.

2. Verify that the front and rear Service Required LEDs are not lit.

3. If the previous steps indicate that no faults have been detected, then the main module motherboard has been replaced successfully.

4. Set ILOM date/time  (-> set /SP/clock datetime=MMDDhhmmYYYY.ss)

NOTE: In case the FW upgrade via ILOM BUI fails, please use the CLI method (see example in doc 2019500.1). You may need a source of TFTP in order to upgrade firmware via CLI commands, for details refer to: Solaris[TM] Operating System: How to set-up a TFTP server. (Doc ID 1004474.1).

NOTE: In some cases when updating the SysFW via CLI (and during CLI execution), it may fail with the following error:

When that happens, refer to doc 1517032.1 for the workaround steps (confirmed by FSEs to be a successful workaround in resolving the issue).

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTIONS ARE REQUIRED TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:
Boot system and monitor boot sequence for errors. Test functionality of system:

1. If the server fails to boot from the boot disk,  confirm with the customer if the boot disk is under a RAID Volume.

    reference: Doc ID 1387771.1 Troubleshooting inability to see a pre-existing RAID volume on T3, T4 & T5 systems

2. Run the Solaris "fmadm faulty" and SP/ILOM "show faulty" command (if only ALOM is supported run "showfaults -v" command) to verify that the fault has been cleared.
3. Perform one of the following tasks based on your verification results:
   * If the previous steps did not clear the fault, refer to doc 1004229.1 for information about the tools and methods you can use to diagnose and clear
     component faults.
   * If the previous steps indicate that no faults have been detected, the component has been replaced successfully. No further action is required
4. Restart software applications per applicable administration guides to resume system operation.
