• Diagnostic program type and version level
• Hardware configuration (print screen of the system summary)
• UEFI firmware level
• TMM 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
• TMM 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 215 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:
• Recovery BIOS Function
• Recovery BIOS Function by SW1
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 Lenovo service representative.
To download the server firmware update package from the World Wide Web, go to
