UEFI error messages can be generated when the server starts up (POST) or while the server is running. UEFI error messages are logged in the Lenovo XClarity Controller event log in the server.
For each event code, the following fields are displayed:
Informational. The event was recorded for audit purposes, usually a user action or a change of states that is normal behavior.
Warning. The event is not as severe as an error, but if possible, the condition should be corrected before it becomes an error. It might also be a condition that requires additional monitoring or maintenance.
Error. The event is a failure or critical condition that impairs service or an expected function.
