ELOM-to-ILOM Migration User’s Guide

Use the procedures in this section to recover from a failed upgrade on a Sun Blade X6250 or X6450 server module. A failed upgrade has occurred if any of the following messages appears during the upgrade process:

Firmware size incorrect.
Incorrect image type.
BIOS upgrade failed.

Caution - The procedures listed in this section should be used only for system recovery. These procedures do not preserve BIOS setting, and do not preserve ELOM or ILOM configuration settings.

You have the following recovery options:

Recovering a Corrupt SP on Sun Blade X6250 and X6450 Server Modules

If the SP does not boot or is inaccessible, use this procedure to recover the SP firmware on your Sun Blade X6250 or Sun Blade X6450 server module.

Before You Begin

You need the following:

• A DOS-bootable USB flash drive
• Multi-port dongle cable
• Keyboard, video and mouse

1. Prepare the DOS-bootable USB flash drive, and copy the following files from the Tools and Drivers CD to the USB flash drive:

• \firmware\elom_to_ilom\dos\SOCFLASH.EXE
• \firmware\elom_to_ilom\dos\DOS4GW.EXE

2. Copy the server module-specific binary (.bin) file from the Tools and Drivers CD to the USB flash drive:

3. Connect the multi-port dongle cable to the UCP connector on the front of the server module.

4. Connect a keyboard, video, and mouse (KVM) to the multi-port dongle cable.

5. Insert the DOS-bootable USB flash drive into a USB port on the multi-port dongle cable.

6. Power on the server module.

7. Watch the display and when prompted press F8.

8. Select to boot the server using the DOS-bootable USB flash drive.

The server boots to DOS, and a DOS prompt appears:
>

9. At the DOS prompt, enter the following server module-specific command:

• For the Sun Blade X6250:

> socflash -p 1 -v -f 6250ixx.bin

• For the Sun Blade X6450:

> socflash -p 1 -v -f 6450ixx.bin

The flash upgrade to ILOM starts. The upgrade takes approximately 10 minutes. When the upgrade finishes, the DOS prompt appears.

>

10. When the DOS prompt appears, eject the server module from the chassis backplane to remove power.

You do not have to remove the server from the chassis.

11. After 30 seconds, insert the server module fully into the chassis, and power on the server.

12. Verify that the server module is now ILOM-based by logging in to the web GUI or the CLI.

For information about how to view ILOM version information, see the Integrated Lights Out Manager 2.0 User’s Guide.

Recovering a Corrupt BIOS

To recover a corrupt BIOS, you first must determine whether the SP is ELOM-based or ILOM-based. Once you know the status of the SP, you then need to downgrade the SP and repeat the upgrade procedure.

1. Determine which type of SP firmware is installed using either the web GUI or the CLI:

• Web GUI method:

a. Enter the SP address in a web browser.

The login screen appears.

b. Note the title of the login screen.

• If the title states, Embedded Lights Out Manager, the SP is ELOM-based.

The transitional version of ELOM is designated with red lettering.

• If the title states, Integrated Lights Out Manager, the SP is ILOM-based.

c. Log in to the web GUI.

The main screen appears.

d. To view version information, click the System Information tab.

The System Information submenu tabs appear.

e. Click the Version tab.

Version information appears.

• The transitional ELOM version for the X6250: 028

The transitional ELOM version for the X6450: 053

• The ILOM version is at least: 2.0.3.6

• CLI method

a. Log into the SP via ssh.

The SP version is displayed, and the CLI prompt appears:
->

b. To view formatted version information enter the version command at the CLI prompt:

-> version

• The transitional ELOM version for the X6250: 028

The transitional ELOM version for the X6450: 053

• The ILOM version is at least: 2.0.3.6

2. Based on the status of the SP, repeat the upgrade procedure to continue the migration process:

• If the SP is transitional ELOM:

a. Return (upgrade) the SP to the original version of ELOM and restart the migration process.

• If the SP is ILOM-based:

a. Downgrade the SP to the transitional version of ELOM (see Chapter 6).

b. After downgrading to the transitional version of ELOM, migrate to ILOM using one of the following procedures:
