REMOVAL/REPLACEMENT INSTRUCTIONS

PROBLEM OVERVIEW: replace a failed Service Processor

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? :
The customer should conduct an orderly software system shutdown. Then power down system and disconnect the power cords. A data backup is not a pre-requisite but is a wise precaution.

 
WHAT ACTIONS ARE REQUIRED:

A) Remove the Service Processor

The service processor is a cold-service component that can be replaced by a customer.

Note: Following SP/ILOM replacement if any device used by the LDOM configuration is disabled or faulted, the system will attempt to boot into a degraded configuration (if possible) or will revert to the factory-default profile. So, if the system is using Oracle VM (LDom) we recommend as a precaution to perform a backup of the LDom configuration (per doc 1019720.1) prior to SP replacement.

1. Back up the service processor configuration information before removing the service processor.

At the ILOM prompt, type:

-> cd /SP/config
-> dump -destination uri target

The acceptable values for uri are:
- tftp
- ftp
- sftp
- scp
- http
- https

- target is the remote location where you want to store the configuration information.

For example:

-> dump -destination tftp://129.99.99.99/pathname

2. Remove the main module from the server.

3. Take the necessary ESD precautions.

4. Locate the service processor on the main module.

5. Grasp the service processor by the two grasp points, and lift up to disengage the service processor from the connectors on the motherboard.

6. Lift the service processor up and away from the motherboard

B) Install the Service Processor

1. Lower the side of the service processor with the Align Tab sticker down on the service processor tab on the motherboard.

2. Lower the other side of the service processor down and press down on the service processor to seat it into the connectors on the motherboard.

3. Install the main module back into the server.

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

If the replacement service processor detects that the service processor firmware is not compatible with the existing host firmware, 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, otherwise go to Step 6.

5. Update the system firmware
a. Download the system firmware from My Oracle Support, the latest is SysFW 8.9.8, <SunPatch:152477-04>
b. Configure the service processor as network port to enable the firmware image to be downloaded.
Refer to the Oracle ILOM documentation for network configuration instructions.
c. Download the system firmware.
Follow the firmware download instructions in the Oracle ILOM documentation and the specific firmware patch.

Note - You can load any supported system firmware version, including the firmware revision that had been installed prior to the replacement of the service processor.

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

If that happens, refer to doc 1517032.1 for the workaround steps (confirmed by FSEs) and the fix.

6. Restore the service processor configuration information that you backed up earlier.

At the ILOM prompt, type:

-> cd /SP/config
-> load -source uri target

The acceptable values for uri are:
- tftp
- ftp
- sftp
- scp
- http
- https

- target is the remote location where you stored the configuration information.

For example:

-> load -source tftp://129.99.99.99/pathname

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

8. Verify the service processor.

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). See also doc 2076315.1 in References.

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. 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.
2. 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
3. Restart software applications per applicable administration guides to resume system operation.
