– 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 levelv Hardware configuration (print screen of the system summary)v UEFI firmware levelv IMM firmware levelv Operating system softwareYou can solve some problems by comparing the configuration and software setupsbetween working and nonworking servers. When you compare servers to eachother for diagnostic purposes, consider them identical only if all the followingfactors are exactly the same in all the servers:v Machine type and modelv UEFI firmware levelv IMM firmware levelv Adapters and attachments, in the same locationsv Address jumpers, terminators, and cablingv Software versions and levelsv Diagnostic program type and version levelv Configuration option settingsv Operating-system control-file setupSee Appendix D, “Getting help and technical assistance,” on page 829 forinformation 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 codeupdates. If the device is part of a cluster solution, verify that the latest level ofcode is supported for the cluster solution before you update the code.If the server firmware has become corrupted, such as from a power failure duringan 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 ServicePack.v Out-of-band method: Use the IMM web interface to update the firmware, usingthe 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 tohttp://www.ibm.com/supportportal/.Chapter 4.
