Identifying the Terminal Type to the Diagnostics
When you run diagnostics, you must identify which type of terminal you are using. If the
terminal type is not known when the FUNCTION SELECTION menu is displayed, the
diagnostics do not allow you to continue until a terminal is selected from the DEFINE
TERMINAL option menu.
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 Hardware Management Console for pSeries
(HMC) virtual terminal window being used, you may be unable to read the screen, use
the function keys, or use the Enter key. Bypass these difficulties 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 displays.
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.
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 On full system partitions, 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.
