This procedure is for boot failures that terminate very early in the boot process.
Even if the customer cannot update the firmware on this system at this time, all of their systems should be updated to the latest firmware level as soon as possible to help prevent this problem from occurring on other systems.
Perform the following:
If the service processor fails very early in the boot process, the logical control panel on the HMC will not be available. In that case, use the UEPO switch to completely remove power from the system, then restore power and watch the HMC to see if the logical control panel is available.
If the HMC still says that it cannot communicate with the managed system after the power is cycled, replace the service processor using symbolic FRU SVCPROC. This ends the procedure.
If the HMC can communicate with the managed system after the power is cycled, open the logical control panel and look for the service processor to reach standby. If the service processor reaches standby, this ends the procedure. If it does not reach standby, replace the service processor using symbolic FRU SVCPROC. This ends the procedure.
