Note: The user and operating system interfaces of the system firmware are based on the Open Firmware standard. Detailed system information is provided through the Open Firmware device tree. You can use the client interface and Run-Time Abstraction Services (RTAS) to run management functions. BMC firmware v Communicates with advanced management module v Controls power on v Initializes the board, including the Cell/B.E. processors and clock chips v Monitors the physical board environment System firmware v Takes over when the BMC has successfully initialized the board v Acts as the basic input/output system (BIOS) v Includes boot-time diagnostics and power-on self test v Prepares the system for the operating system boot The packages are delivered separately and do not follow the same versioning scheme. IBM provides two basic update options for updating or ″flashing″ the firmware: online and offline. The offline method requires you to use an alternate bootable media to restart the server and perform the firmware update. For greater convenience and flexibility, IBM now also provides online updates that you can install while the operating system is running. The online method allows you to run the update at any time, with the flexibility to restart the server at a time when it is most convenient to do so. As a best practice, use the online update packages to perform all of your basic update functions IBM periodically makes updates to both BMC and system firmware. These may be downloaded from http://www.ibm.com/support/us/en/. Note: To avoid problems and to maintain proper system performance, always make sure that both the BMC firmware and the system firmware are at the same level for all BladeCenter QS21 servers within the BladeCenter unit. Updating steps Complete the following steps to update the BMC and system firmware images: 1. Check the revision level of the firmware on the blade server and the level of the updates on http://www.ibm.com/support/us/en/. If the level on the Web site is higher than the version currently installed, continue with the updating steps. 2. Download the firmware updates. 3. Boot the operating system if it is not running already. 4. Update the BMC firmware using the update package or the Management Module. See "Updating the BMC firmware" on page 18 for further information. 5. Restart the blade server. This boots the blade server with the new BMC firmware. 6. Update the system firmware image. See "Installing the system firmware" on page 20 for further information. 7. The system reboots. This boots the blade server with the new system firmware. 8. Shut down the blade server. 16 BladeCenter QS21 Type 0792: Problem Determination and Service Guide
