– Is the failure repeatable?
– Has this configuration ever worked?
– What changes, if any, were made before the configuration failed?
– Is this the original reported failure?
v Diagnostic program type and version level
v Hardware configuration (print screen of the system summary)
v UEFI firmware level
v IMM firmware level
v 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:
v Machine type and model
v UEFI firmware level
v IMM firmware level
v Adapters and attachments, in the same locations
v Address jumpers, terminators, and cabling
v Software versions and levels
v Diagnostic program type and version level
v Configuration option settings
v Operating-system control-file setup
See Appendix D, “Getting help and technical assistance,” on page 781 for
information about calling IBM 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:
v In-band method: Recover server firmware, using either the boot block jumper
(Automated Boot Recovery) and a server Firmware Update Package Service
Pack.
v Out-of-band method: Use the IMM web interface to update the firmware, using
the latest server firmware update package.
Note: You can obtain a server update package from one of the following sources:
v Download the server firmware update from the World Wide Web.
v Contact your IBM service representative.
To download the server firmware update package from the World Wide Web, go to
