Updating firmware and device drivers

IBM periodically makes UEFI code, service processor (IMM) firmware, diagnostic firmware updates, and device driver updates available for the blade server. Provisioning is the set of actions you take to update the firmware and device drivers, and install the operating system. Several tools are available to help update the firmware and device drivers in the provisioning process. Use the instructions that are included with the downloaded files.

  1. Some cluster solutions require specific code levels or coordinated code updates. If the device is part of a cluster solution, verify that the latest level of code is supported for the cluster solution before you update the code.
  2. Before you update the firmware, be sure to back up any data that is stored in the Trusted Platform Module (TPM), in case any of the TPM characteristics are changed by the new firmware. For instructions, see your encryption software documentation.
  3. Installing the wrong firmware or device-driver update might cause the blade server to malfunction. Before you install a firmware or device-driver update, read any readme and change history files that are provided with the downloaded update. These files contain important information about the update and the procedure for installing the update, including any special procedure for updating from an early firmware or device-driver version to the latest version.
Important: To avoid problems and to maintain system performance, always make sure that the UEFI code, service processor (IMM) firmware, and diagnostic firmware levels are consistent for all blade servers within the BladeCenter unit.
