Recovering from a UEFI update failure
Use this information to recover from a UEFI update failure in the blade server.
Important: 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.
If the server firmware has become corrupted, such as from a power failure during an update, you can recover
the server firmware in one of four ways:
• In-band manual recovery method (See “In-band manual recovery method” on page 49.)
• Out-of-band manual recovery method (See “Out-of-band manual recovery method” on page 50.)
• In-band automated boot recovery method (See “In-band automated boot recovery method” on page
51.)
• Out-of-band automated boot recovery method (See “Out-of-band automated boot recovery method”
on page 52.)
In-band manual recovery method
To recover the server firmware and restore the server operation to the primary bank, complete the following
steps:
Step 1. Download the blade server UEFI firmware update from the World Wide Web (see “Updating
firmware and device drivers” on page 30).
Step 2. Turn off the server (see “Turning off the blade server” on page 12).
Step 3. Remove the blade server from the BladeCenter unit (see “Removing the blade server from the
BladeCenter chassis” on page 66).
Step 4. Remove the server cover. See “Removing the blade server cover” on page 71 for more information.
Step 5. Locate the UEFI boot block recovery switch (SW2-7) on the system board (see “System-board
switches” on page 13).
Step 6. Use your finger to move switch SW2-7 to the ON position.
Step 7. Replace the cover and reinstall the blade server in the BladeCenter unit, making sure that the media
tray is selected by the relevant blade server. See “Installing the blade server cover” on page 73 and
“Installing a blade server in a BladeCenter chassis” on page 67.
Step 8. Restart the blade server (see “Turning on the blade server” on page 11). The system begins the
power-on self-test (POST).
Step 9. Boot the server to an operating system that is supported by the firmware update package that you
downloaded.
Step 10. Perform the firmware update by following the instructions that are in the firmware update package
readme file.
