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.
For each event code, the following fields are displayed:
Severity | Description |
---|---|
Informational | An informational message is something that was recorded for audit purposes, usually a user action or a change of states that is normal behavior. |
Warning | A warning 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 | An error typically indicates a failure or critical condition that impairs service or an expected function. |
Perform the steps in the order shown until the problem is solved. After you perform all of the actions that are described in this field, if you cannot solve the problem, contact Lenovo Support.
