Recovering The Server Firmware (Uefi Update Failure); In-Band Manual Recovery Method - Lenovo System x3650 M4 Installation And Service Manual

• IMM firmware level
• Operating system software
You can solve some problems by comparing the configuration and software setups between working and
nonworking servers. When you compare servers to each other for diagnostic purposes, consider them
identical only if all the following factors are exactly the same in all the servers:
• Machine type and model
• UEFI firmware level
• IMM firmware level
• Adapters and attachments, in the same locations
• Address jumpers, terminators, and cabling
• Software versions and levels
• Diagnostic program type and version level
• Configuration option settings
• Operating-system control-file setup
See Appendix D "Getting help and technical assistance" on page 1189 for information about calling Lenovo
for service.

Recovering the server firmware (UEFI update failure)

Use this information to recover the server firmware.
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 the following way:
• In-band method: Recover server firmware, using either the boot block jumper (Automated Boot
Recovery) and a server Firmware Update Package Service Pack.
• Out-of-band method: Use the IMM web interface to update the firmware, using the latest server
firmware update package.
Notes: You can obtain a server update package from one of the following sources:
• Download the server firmware update from the World Wide Web.
• Contact your service representative.
To download the server firmware update package from the World Wide Web, go to
http://www.lenovo.com/support.
The flash memory of the server consists of a primary bank and a back up bank. You must maintain a
bootable UEFI firmware image in the back up bank. If the server firmware in the primary bank becomes
corrupted, you can either manually boot the back up bank with the UEFI boot backup jumper (JP2), or in the
case of image corruption, this will occur automatically with the Automated Boot Recovery function.
