IBM RS/6000 7025 manual Running the Diagnostics from a TTY Terminal

set	up to	boot from a server, the diagnostics are run in the same manner as
are	from	disk.

ŸIf the diagnostics are loaded from disk or a server, you must shutdown the

to disk	data.	This is	done in	one	of two	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 shutdown the AIX operating system.

– If the diagnostics were loaded in maintenance or concurrent mode, enter th shutdown -F command.

ŸUnder some conditions the system may stop, with instructions displayed on attached displays and terminals. Follow the instructions to select a console display.

certain attributes are used. These attributes are set as if the diagnostic using a 3161 display terminal. The following tables list attributes for the 31 ASCII Display Terminal and for two other ASCII display terminals commonly
