This task provides instructions for running UEFI diagnostics manually from the CLI through the host console.

Power off the server:
1. Type stop -f /SYS.
2. To stop the system, type y.
  The System OK LED on the front panel is blinking.
Start a serial console redirection:
1. Log in to the Oracle ILOM command-line interface (CLI) as root.
2. Type start /HOST/console.
3. To start the host console, type y.
To change the directory to /HOST/diag, type cd /HOST/diag.
To set manual mode, type set mode=manual.
Start the UEFI diagnostics.
1. Type start /HOST/diag.
2. To start the UEFI diagnostic, type y.
The server automatically boots the UEFI shell. No more action is necessary.

The system displays boot messages, and displays the following startup messages.

To view the progress of the diagnostic tests in Manual mode, type show /HOST/diag status.
The Diagnostics Status field indicates the progress of the diagnostic tests.
To display the available commands, type udiag -hv.

Stop the diagnostic tests.

Type stop /HOST/diag.
To stop the UEFI diagnostics, type y.

Caution - If there is an unexpected AC power cycle and a test is in progress, configure Diagnostics mode again starting from Step 1. Internal variables could be corrupted and setting a new mode or resetting the same mode fixes any potential issue.

To resume running the diagnostic tests, type start /HOST/diag.
Note - To check the history of the test using Oracle ILOM Event logs, type: show /SP/logs/event/list/ type==diags.
To finish the Diagnostics activities, type set /HOST/diag/ mode=disabled.
