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.
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 additional information about updating firmware and device drivers, see UEFI Compliant Firmware on
System x® and BladeCenter® Servers and the Flex System Quick start guides, and the
Firmware Update
Guides athttp://www.ibm.com/support/entry/ portal/docdisplay?lndocid=MIGR-5091991 (you might need to

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 II detects the error and automatically
switches to the backup page to start the compute node. If this happens, a POST message
Booted from
backup POST/BIOS 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 “Updating firmware and device drivers” on page 21).
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 is displayed only if the compute node boots from the backup
page because of an ABR condition.
If the attempt to flash the primary page results in the compute node not booting and the check log LED is not
lit, you can manually restore the UEFI code. To manually restore the UEFI code, complete the following steps.
Note: If the check log LED is lit, the compute node is booting from the backup image, and changing the
boot backup UEFI switch to the On position changes nothing.
1. Before you begin, read “Safety” on page iii and “Installation guidelines” on page 637.
2. Turn off the compute node (see “Turning off the compute node” on page 16).
3. Remove the compute node from the Flex System chassis (see “Removing a compute node from a
chassis” on page 639).
4. Remove the cover (see “Removing the compute node cover” on page 643).
