UEFI/POST diagnostic codes

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:

Event identifier
An identifier that uniquely identifies an event.
Event description
The logged message string that appears for an event.
Additional information to explain why the event occurred.
An indication of the level of concern for the condition. The severity is abbreviated in the event log to the first character. The following severities can be displayed.
Table 1. Event severity levels.

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.
User response
The actions that you should take to resolve the event.

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.

Booting server to F1 setup menu
In additional to the normal process in booting the server to the F1 setup menu (pressing F1 when <F1 Setup> is displayed), there are two other ways for users to choose.
  • Method 1
    1. Proceed to the IMM2 website.
    2. Select Server Management tab.
    3. Select Server Power Action.
    4. Select Boot Server to F1 Setup.
  • Method 2

    Use Advanced Settings Utility (ASU) program. Command line is shown as follows: asu.exe set IMM.ForceBootToUefi enable

  1. When you press Ctrl+Alt+Delete on F1 setup menu panel, the system will reboot automatically and ask you to enter password again.
  2. Most F1 Setup settings, which can be load default, are chipset related items or less user input required items. However, when adjusting the iSCSI settings, be aware that the iSCSI configurations cannot be restored to default. This is to avoid iSCSI items losing its configurations, which may result in the system not being able to boot to the operating system.

The following is the list of the UEFI/POST error codes and suggested actions to correct the detected problems.
