Recovering A Uefi Image - Lenovo Flex System x440 Compute Node Installation And Service Manual

To provision a compute node with updated firmware and device drivers by using Lenovo ToolsCenter
Bootable Media Creator and the Flex System Manager management software, complete the following
steps:
1. Download Lenovo ToolsCenter Bootable Media Creator to a computer that is connected over the
management network to the Flex System Manager management software that is managing the
compute node.
2. Create the bootable media of firmware and device driver updates.
3. Connect to the Flex System Manager management software that is managing the Flex System
chassis in which the compute node is installed.
4. From Flex System Manager Chassis Manager, select the compute node. In the Actions column,
select Remote Control.
Note: The user ID that you use to log in to Flex System Manager management software must have
sufficient user permissions to manage the compute node.
5. From the Remote Control session, mount the bootable media (using Remote Media).
6. Start the compute node to boot the media and install the updates.
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.

Recovering a UEFI image

Use this information to recover a UEFI image.
The compute node has an advanced recovery feature that automatically switches to a backup UEFI page if
the UEFI code in the compute node has become damaged, such as from a power failure during an update.
The flash memory of the compute node consists of a primary page and a backup page. If the UEFI code in
the primary page is damaged, the integrated management module detects the error and automatically
switches to the backup page to start the compute node. If this happens, a POST message Booted from
backup UEFI image is displayed, the check log LED is lit, and an automatic BIOS recovery (ABR) condition
occurs. The backup page version might not be the same as the primary page version.
You can then recover or restore the original primary page UEFI.
Note: Changes are made periodically to the Lenovo website. The actual procedure might vary slightly from
what is described in this document.
To recover the UEFI code and restore the compute node operation to the primary page, complete the
following steps:
Step 1. Update the UEFI code (see
Step 2. Restart the compute node.
Step 3. At the firmware splash screen, press F3 when prompted to restore to the primary bank. The
compute node boots from the primary bank.
Note: The prompt to press F3 displays only if the compute node boots from the backup page due
to an ABR condition.
