## How to Update the ILOM and System BIOS Using the Command-Line Interface

Before You Begin

- Identify the version of ILOM that is currently running on your system. See Determining Current Firmware Versions.

- Download the firmware image for your server from the Sun platform product web site. See How to Download Firmware Updates.

- Copy the firmware image to a local server using a supported protocol (TFTP, FTP, HTTP, HTTPS).

- Obtain an ILOM user name and password that has Admin (a) role account privileges. You must have Admin (a) privileges to update the firmware on the system.

- To verify that you have network connectivity to update the firmware, type -> `show /SP/network`.

Note - The firmware update process takes about six minutes to complete. During this time, do not perform other ILOM tasks. When the firmware update is complete, the system reboots automatically.

1. Log in to the ILOM CLI.

   See Connecting to the ILOM for more info.

2. Type the following command to load the ILOM firmware image:

   ->`load –source` supported_protocol://server_ip/path_to_firmware_image/filename.`ima`

   If your system has an ILOM 2.x version, you must use the TFTP protocol to load the firmware image. If your system has a ILOM 3.x version, you can use TFTP, FTP, HTTP, or HTTPS.

   A note about the firmware update process is displayed, followed by message prompts to load the image. The text of the note depends on your server platform.

3. At the prompt for loading the specified file, type y for yes or n for no.

   The prompt to preserve the configuration appears.

4. At the preserve configuration prompt, type `y` for yes or `n` for no.

   Type `y` to save your existing ILOM configuration and to restore that configuration when the update process is completed.

   Typing `n` at this prompt advances you to another platform-specific prompt.

   A prompt to postpone the BIOS update appears.

5. When asked if you want to force the server off to upgrade the BIOS, type `y` for yes or `n` for no.

   Note - If you answer no (n) to the prompt, the system postpones the BIOS update until the next time the system reboots. If you answer yes (y) to the prompt, the system automatically updates the BIOS, if necessary, when updating the firmware.

   The system loads the specified firmware file and then automatically reboots to complete the firmware update.

6. Reconnect to the ILOM server SP or CMM using an SSH connection and using the same user name and password that you provided in Step 1 of this procedure.

   Note - If you did not preserve the ILOM configuration before the firmware update, you will need to perform the initial ILOM setup procedures to reconnect to ILOM.

7. To ensure that the proper firmware version was installed, at the CLI prompt, type:

   `-> version`
