Preparing to Upgrade the ILOM Firmware

Here is the general process flow for ILOM firmware updates.

  1. Download the new firmware image from http://www.sun.com/servers/blades/8000/downloads.jsp.

  2. Copy the new firmware image to the network or a local file system that is accessible to ILOM.

  3. Upgrade the firmware on each SP in the system using the ILOM web interface or CLI.

  4. Upgrade the firmware on the CMM(s) in the system using the ILOM web interface or CLI

Note

You must run the same version of ILOM firmware on the CMM(s) and all of the SPs in the system.

About Upgrading the Firmware on an SP

A single firmware image contains both the ILOM SP and BIOS firmware. Only the components that need to be upgraded will be upgraded. When the BIOS is updating, the host is held in reset until the firmware flash operation is complete.

You can update your SP firmware by logging directly into that SP, or by drilling down to that SP from the CMM.

About Upgrading the Firmware on a CMM

If your system has one CMM, follow the procedure for Upgrading the ILOM Firmware. Be aware that you cannot use the CMM during the Upgrade procedure, rendering the chassis unmanageable for this period.

About Upgrading the Firmware on a CMM in a Redundant Configuration

If your system has two CMMs, follow this process flow to minimize interruption to users:

  1. Follow the procedure for Upgrading the ILOM Firmware on the standby CMM first.

  2. Promote the standby CMM to the active CMM. See Managing CMM Redundancy.

  3. Upgrade the firmware on the other CMM, now the standby.

  4. Assign either CMM the active role. See Managing CMM Redundancy.
