Before You Begin
To diagnose hardware issues on Oracle x86 systems, you need the Reset and Host Control (r) role enabled.
If you choose to run diagnostics in Manual mode, or if you want to monitor the progress of diagnostic tests in Enabled or Extended mode, do one of the following:
Start a host console redirection.
Set up a serial console.
Connect a keyboard, video, and mouse to your system.
For details about launching a redirection session, see Using Remote KVMS Consoles for Host Server Redirection in Oracle ILOM Administrator’s Guide for Configuration and Maintenance Firmware Release 3.2.x.
cd /HOST/diag
set mode=[disabled|enabled|extended|manual]
For details about diagnostics levels, see Selecting a Diagnostic Test Level.
start /HOST/diag
If you chose to run the diagnostic tests in Manual mode, the UEFI Diagnostics test selection screen appears on the host console.
show /HOST/diag status
set mode=[disabled|enabled|extended|manual]
For details about diagnostics levels, see Selecting a Diagnostic Test Level.
show /HOST/diag status
If you ran UEFI Diagnostics in Enabled or Extended mode, the diagnostics mode was automatically reset to Disabled. You must return the server to Disabled diagnostics mode before you can set the diagnostics mode to Enabled or Extended.
