Downgrading From ILOM to ELOM |
Use this chapter to downgrade Sun Fire X4150 and Sun Fire X4450 servers and Sun Blade X6250 and Sun Blade X6450 server modules from ILOM to ELOM. While the downgrade preparation procedures are the same for both the Sun Fire servers and the Sun Blade server modules, the downgrade procedures are different. Use the appropriate downgrade procedure for your server or server module. This chapter contains the following sections:
You might find it necessary to downgrade your ILOM-based systems to ELOM-based systems first and then upgrade all the servers to ILOM at a later date. This section describes this process.
| Note - Sun recommends that you migrate your servers to ILOM as soon as possible. |
The Product Notes contains the most up-to-date information about your server, including hardware, software, and BIOS and SP issues. Review the Product Notes for information about downgrading from ILOM to ELOM. Use the following procedure to access and view or download the most recent versions of the Product Notes and ELOM and ILOM documentation.
|
1. See the Product Notes for your server or server module for information about the availability of ILOM and the ELOM-to-ILOM conversion:
a. Open your browser and go to one of the following:
b. Click to expand the documentation collection for your server.
2. Choose to view or download the Product Notes.
3. Review the documentation for information specific to the ILOM-to-ELOM downgrade.
The ILOM-to-ELOM downgrade process does not retain ILOM configuration settings. If you would like to review and record ELOM-compatible ILOM settings (for example, network information and user accounts), use the procedure in this section to access and record your ILOM configuration settings. If you do not wish to record ILOM configuration settings before downgrading to ELOM, see Downgrading Sun Fire X4150 and X4450 Servers From ILOM to ELOM.

1. In your browser’s address bar, type the IP address of the server’s SP.
where xxx.xxx.xxx.xxx is the IP address of the SP.
The ILOM web GUI login screen appears.
2. Log in as root or as a user with administrator privileges.
3. Record the information for any of the configuration settings that you need to note.
The downgrade procedures for the Sun Fire servers are different from the downgrade procedures for the Sun Blade server modules. Use the appropriate procedure for your server or server module:
The procedures in this section describe how to perform the ILOM-to-ELOM downgrade.
Review the procedures in this section.
Depending on the procedure you choose, you also might need the following:
You have the following downgrade options:
|
To Downgrade From ILOM to ELOM Using the Tools and Drivers CD |
|
|
To Downgrade From ILOM to ELOM Using a DOS-bootable USB Flash Drive |
|
|
To Downgrade From ILOM to ELOM Using the Tools and Drivers CD |
|
|
1. Set up your server to respond to boot and POST messages and prompts.
Use a serial terminal or a computer running terminal-emulation software.
3. Insert the Tools and Drivers CD.
The server boots from the CD, and the Tools and Drivers menu appears.
4. Select the option to Exit to DOS (option 3).
5. Navigate to the \recovery\elom\ directory:
| Tip - Use the DOS dir command to list the contents of the directory. |
A menu appears with the following options:
1. To recover both SP and BIOS firmware
7. Select the option to recover the SP and BIOS firmware (option 1).
The flash process starts the downgrade.
8. When the downgrade to ELOM is finished, power cycle and boot the server.
|
|
1. Prepare a DOS-bootable flash drive.
2. Set up your server to respond to POST messages and boot prompts.
3. Power on and boot the server.
Log in to the operating system.
4. Insert and mount the DOS-bootable flash drive.
5. Insert and mount the Tools and Drivers CD.
6. Copy the contents of the \recovery\elom directory from the Tools and Drivers CD to the flash drive.
For this procedure you need the \recovery\elom\recovery.bat file and accompanying files.
7. Power on and boot the server.
A message appears prompting you to Press F2 to enter the BIOS Setup Utility.
8. Press F2 to enter the BIOS Setup Utility.
The BIOS Setup Utility menus appears.
9. Change the boot device priority; make the flash drive the primary boot device.
Use the arrow keys to navigate the menus. See the Service Manual for information about the BIOS screens for your server.
10. Save and exit the BIOS Setup Utility.
The server boots from the flash drive and a DOS prompt appears:
11. At the DOS prompt, run the recovery.bat file by entering the following command:
A menu appears with the following options:
1. To recover both SP and BIOS firmware
12. Select the option to recover the SP and BIOS firmware (option 1).
The flash process starts the downgrade.
13. When the downgrade to ELOM is finished, power cycle and boot the server.

Caution - This downgrade procedure uses socflash.exe, which is a recovery tool. Do notuse the .pkgfile format for recovery procedures. Use the .binrecovery image instead. |
1. Prepare a DOS-bootable USB flash drive.
2. Copy all the files from the /recovery/elom/sp directory on the Tools and Drivers CD v2.0 to the USB flash drive:
3. Set up your server to respond to boot and POST messages and prompts.
Use a serial terminal or a computer running terminal-emulation software.
4. Remove AC power from the system to be flashed.
5. Insert the bootable flash drive into the USB port.
6. Connect AC power, power on the system, and watch the boot and POST messages.
a. A message appears stating that the BMC was not found.
The system takes up to five minutes to boot.
b. Press F8 to get a list of boot devices.
c. Choose to boot from the flash drive.
7. The server boots from the flash drive, and a DOS prompt appears:
8. At the DOS prompt, run the following command using the .bin file:
where sp is the name of the SP .bin file.
> socflash -p 2 -f s92v410.bin
9. After a successful flash use the -r option to reset the SP:
10. Access the BIOS Setup Utility to confirm that the BIOS does not report that the BMC was not found.
The socflash.exe utility does not update the BIOS.
11. To downgrade the BIOS, use the ELOM web GUI or CLI procedures in the Embedded Lights Out Manager Administration Guide.
The procedure in this section describes how to perform the ILOM-to-ELOM downgrade for the Sun Blade X6250 and Sun Blade X6450 server modules. To perform the downgrade to ELOM, you must short jumpers on the motherboard (MB). Additionally, you must use the ELOM socflash.exe utility. Do not use the ILOM utility.
This procedure does not retain any BIOS or ILOM configuration settings.

3. Remove the server module from the chassis (for proper removal procedures, see the Service Manual for your server).
4. Remove the server module cover (see the Service Manual for your server).
5. Do one of the following to short the jumpers on the MB:
For the location of the jumpers, see the service processor recovery procedures in the appropriate Service Manual.
6. With the pins shorted, install the server module cover, and insert the server into the chassis (for proper insertion procedures, see the Service Manual for your server).
