Recovery from a Failed ILOM Upgrade for Sun Fire X4150 and X4450 Servers
To Recover the ELOM BIOS Firmware Using the CLI 1. Ensure that the server is in standby power mode.
2. Copy the transitional ELOM remote flash file from the Tools and Drivers CD to your TFTP server.
Server
File Name
Sun Fire X4150
\remoteflash\elom_to_ilom\X4150-026_450
Sun Fire X4450
\remoteflash\elom_to_ilom\X4450-450_3B17
3. Access the CLI.
For CLI access options, see the
Embedded Lights Out Manager Administration Guide for your server.
Note - The CLI commands, syntax, and namespaces in this section might be different from the commands, syntax, and namespaces used for your server; see the
Embedded Lights Out Manager Administration Guide for your server for the appropriate commands, syntax, and namespaces.
4. Log in to the CLI, and navigate to the TftpUpdate directory. For example:
-> cd /SP/TftpUpdate
5. Use the set command to set the IP address of the TFTP server. For example:
-> set ServerIP=
xxx.xxx.xxx.xxx
where
xxx.xxx.xxx.xxx is the IP address of the TFTP server.
6. Use the set command to set the file name of the ELOM remote flash file.
For example, for the Sun Fire X4450:
-> set Filename=X4450-418-3B17
7. Use the set command to start the TFTP download:
-> set Update=action
8. Select Yes to continue.
Example:
-> cd /SP/TftpUpdate -> set ServerIP=123.456.78.910 -> set FileName=X4450-418-3B17 -> set Update=action getting image... getting image successfully. prepare to update... Prepare OK! Update successful starting update...
9. The ELOM restarts.
The BIOS version information is updated once the server is powered on.
10. When the process finishes, boot the server.
11. Repeat the migration process.
