diagnostics do not allow you to continue until a terminal is selected from the DEFINE
TERMINAL option menu. Select lft for graphical displays.
Undefined Terminal Types
If you specify an undefined terminal type from the DEFINE TERMINAL option menu, the
menu prompts the user to enter a valid terminal type. The menu redisplays until either a
valid type is entered or you exit the DEFINE TERMINAL option.
Resetting the Terminal
If you enter a terminal type that is valid (according to the DEFINE TERMINAL option
menu) but is not the correct type for the ASCII terminal being used, you may be unable
to read the screen, use the function keys, or use the Enter key. These difficulties can be
bypassed by pressing Ctrl-C to reset the terminal. The screen display that results from
this reset depends on the mode in which the system is being run:
v Online normal or maintenance mode - The command prompt appears.
v Standalone mode or online service mode - The terminal type is reset to dumb, the
Diagnostic Operating Instruction panel displays, and you are required to go through
the DEFINE TERMINAL process again.
Running Online Diagnostics
Consider the following when you run the online diagnostics from a server or a disk:
v The diagnostics cannot be loaded and run from a disk until the AIX operating system
has been installed and configured. After the AIX operating system has been installed,
all three modes of diagnostics are available.
v The diagnostics cannot be loaded on a system (client) from a server if that system is
not set up to boot from a server over a network. When the system is set up to boot
from a server, the diagnostics are run in the same manner as they are from disk.
v 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. 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 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.
Running Standalone Diagnostics
Consider the following when you run standalone diagnostics:
v The diagnostic CD must remain in the CD-ROM drive for the entire time that
diagnostics are running.
v The diagnostic CD cannot be ejected from the CD-ROM drive after the diagnostics
have loaded. The CD can only be ejected after the system has been turned off and
then turned on (standalone mode) or after the diagnostics program has terminated
(online concurrent mode).
