v On a full system partition, if the diagnostics are loaded from disk or a server, you must shut down the
AIX operating system before turning off the system unit to prevent possible damage to disk data. Do
this in either of the following ways:
– If the diagnostics were loaded in standalone mode, press the F3 key until DIAGNOSTIC OPERATING
INSTRUCTIONS displays. Then press the F3 key once again to shut down the AIX operating system.
– If the diagnostics were loaded in maintenance or concurrent mode, type the shutdown -F command.
v Under some conditions, the system might stop, with instructions displayed on attached displays and
terminals. Follow the instructions to select a console display.
