Identifying the Terminal Type to the Diagnostics
Note: This is a different task than selecting a console display.
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. 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 which results from this reset depends on the mode in
which the system is being run:
Online Normal or Maintenance Mode - The command prompt appears.
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:
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.
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.
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:
