UEFI Diagnostics Test Modes

Use UEFI diagnostic tests to diagnose server problems and determine root causes of system problems.

You can use either the Oracle ILOM web interface or the command-line interface (CLI) to run UEFI diagnostics. From Oracle ILOM, you select the level of test that you want to perform.

You can run UEFI diagnostics in one of the following modes:

UEFI Diagnostics Test Mode
Description
Disabled
UEFI diagnostics do not run. Use this selection for normal system operation.
After you run UEFI diagnostics tests in Manual mode, stop UEFI Diagnostics, and select Disabled mode to recover the original system status.
Enabled
The server boots automatically and executes a predefined test suite without user intervention. Test output is logged to the uefidiag directory, which you can view in the Oracle ILOM Diag shell. After the diagnostic tests complete, the system automatically shuts down and returns to Disabled diagnostics mode.
Use Enabled mode as a quick test for first-time field installation and prior to installing mission-critical applications to verify system quality. These basic tests typically take between 10 minutes and 1.5 hours, depending on the system configuration.
Extended
The server boots automatically and executes a comprehensive test suite without user intervention. Test output is logged to the uefidiag directory, which you can view in the Oracle ILOM Diag shell. After the diagnostic tests complete, the system automatically shuts down and returns to Disabled diagnostics mode.
Use Extended mode for first-time system installation, after physically transporting the system, any time you add components, and prior to installing production operating systems and mission-critical applications. These extended tests typically take between 15 minutes and 3 hours, depending on the system configuration.
Manual
The server boots to the UEFI shell. Type udiag -hv to display the UEFI Diagnostics commands. View the test output using a remote console or a serial console. After the tests are complete, manually return the diagnostics mode to Disabled.
