Appendix C. UEFI/POST error codes
This topic contains information about the UEFI/POST diagnostic error codes.
Note: This documentation includes references to IBM web sites and information about obtaining service.
IBM is Lenovo's preferred service provider for the System x products.
UEFI/POST diagnostic error codes can be generated when the server starts or while the server is running.
UEFI/POST codes are logged in the IMM event log in the server.

Event identifier

usually a user action or a change of states that is normal behavior.
Warning

corrected before it becomes an error. It might also be a condition that requires
additional monitoring or maintenance.
Error An error typically indicates a failure or critical condition that impairs service or
an expected function.
