Symptoms

It is possible when upgrading the firmware in a V1280/E2900 or Netra 1280/1290 platform using the 'lom -G' command to end up with a mismatch of RTOS and ScApp. 

The mismatch will result in the SC's inability to boot and run System Controller Application, preventing the SC from managing the platform.

Changes

The 'lom -G' command is utilized to upgrade ScApp (otherwise known as lom or generically as the firmware).

Cause

This usually happens as a result of following only parts of the upgrade instructions, or not having read the entire upgrade procedure first.  If you follow the instructions from the lom -G command and do a resetsc immediately after applying the sgsc.flash image, you will end up with a mismatch and a very unhappy system controller.

IMPORTANT NOTES:

• The example below is NOT a reference for how to update the firmware on these systems.
• This document exists because there were some deficiencies in early versions of the readme files which left the instructions unclear.  This has been remedied. 
• The README and install.info should be consulted and followed EXACTLY to avoid upgrade problems.

EXAMPLE of the system firmware mismatch by not following the correct procedure

 

# lom -G /var/tmp/114525-02/sgsc.flash

This program will replace LOM firmware with version 5.18.1

Are you sure you want to continue

Enter 'C' and return to Continue or anything else to Terminate

C

Transferring 6200 kB image to the system controller.

This may take several minutes.

 ...Many lines omitted...

Firmware update complete.

You must reboot the system controller to load the new firmware.

At the lom> prompt enter ''resetsc -y'' to reboot the system controller.

# <---- Typically, this is where a user would fail to read the whole procedure,
and follow the onscreen instructions and hit the Escape sequence here.

lom> resetsc -y

Are you sure you want to reboot the system controller now yes (-y)

Waiting for critical processes to finish. This may take a while.

Critical processes have finished.

...The SC is now partly updated, and on the way to being broken.

..

Rebooting. All telnet connections closed. Reestablish any needed connections.

Sun Fire System Firmware

RTOS version: 39

ScApp version: 5.18.1 Build_01

The RTOS revision is too old for this version of ScApp. ScApp version 5.18.1 requires RTOS version 40 but RTOS version 39 is installed.

You will be prompted to enter a URL where ScApp and RTOS can be

downloaded.

Enter URL :

At this point, the SC is unusable, and does NOT start up into ScApp.

If the IB-SSC ethernet connection is not configured, this is a little trickier since you will have to configure the  IB-SSC ethernet connection from the RTOS.  If you have the IB-SSC ethernet connection configured, and if you have a host on the SC network which has the firmware, you can recover as in an internally documented procedure.

Solution

Resolving this issue requires that you open a service request and speak to an Oracle Support Engineer.  The issue must be validated, and due to the complex nature of the resolution an Oracle Support Engineer will need to guide you through this resolution.

That engineer's task in resolving this issue might be made easier if they are able to utilize Shared Shell to remotely access this host and perform the procedure to resolve the mismatch.  This type of remote access is not always possible, but it's worth validating if this is an option. 

Please remember to specify that you utilized this document ID when opening the Service Request.  The service engineer can pick up at this point and resolve the issue utilizing the internally documented process.

Support engineer instructions for resolving this issue.

If needed assist the customer via Shared Shell in order to avoid dispatching a field resource on site for this resolution.

Enter URL : Enter the absolute path name to the directory where the SC can find the firmware (See below in BOLD).

Enter URL : ftp://root:passwd@129.156.210.160//var/tmp/114525-02

Rebooting the SC to automatically complete the upgrade.

AT THIS POINT, WE HAVE TO REBOOT THE SC.
THE ONLY WAY TO DO SO ON THE V1280/E2900/n1280/n1290
(SINCE WE CAN'T GET TO THE RESET BUTTON)
IS TO POWER-CYCLE THE BOX.

Note: As the hard reset of the SC could potentially interrupt domain operations,
it is recommended that the domain be halted prior to taking the actions below.
