Updating firmware and device drivers

Lenovo periodically makes UEFI code, IMM2 firmware, diagnostic firmware, and device-driver updates available for the compute nodes. Provisioning is the set of actions that you take to update the firmware and device drivers and install the operating system. Several tools are available to help you update the firmware and device drivers in the provisioning process.

Firmware and device drivers in the upper and lower compute nodes are installed and maintained separately.

Attention: Installing the wrong firmware or device-driver update might cause the compute node 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.
  1. Follow the instructions in the readme file that comes with the firmware update.
  2. If you are using a compute node that came with the Ethernet LAN-on-motherboard (LOM) controller integrated on the system board, you can find the device drivers at http://www.emulex.com/downloads/ibm/vfa-software-kits.html.
Important: To avoid problems and to maintain system performance, always make sure that the UEFI code, IMM2 firmware, and diagnostic firmware levels are consistent in all compute nodes in the Flex System chassis. For information about firmware levels, see the Flex System Firmware Update Guides.

For additional information about updating firmware and device drivers, see UEFI Compliant Firmware on System x® and BladeCenter® Servers, the Flex System Quick start guides, andthe Flex System Firmware Update Guides (you might need to register to access this content).
