Running Online Diagnostics
Consider the following when you run the Online Diagnostics from a server or a disk:
Ÿ
The diagnostics cannot be loaded and run from a disk until the AIX operating
system has been installed and configured. After the installation of the AIX
operating system, all three modes of operation are available.
Ÿ
The diagnostics cannot be loaded on a system (client) from a server if that
system is not set up to IPL from a server over a network, or the server has not
been setup to send a service mode IPL of the diagnostics. When the system is
set up to IPL from a server, the diagnostics are executed in the same manner as
they are from disk.
Ÿ
If the diagnostics were loaded from disk or a server, you must shutdown the AIX
operating system before powering the system unit off to prevent possible
damage to disk data. This is done in one of two ways:
– If the diagnostic programs were loaded in Stand-alone mode, press the F3
key until DIAGNOSTIC OPERATING INSTRUCTIONS displays; then follow
the displayed instructions to shutdown the AIX operating system.
– If the diagnostic programs were loaded in maintenance or concurrent mode,
enter the
shutdown -F
command.
Ÿ
Under some conditions the system may stop, with instructions displayed on
attached displays and terminals. Follow the instructions to select a console
display.
Running the Diagnostics from a tty Terminal
Consider the following when you run diagnostics using a tty-type terminal as the
console display:
Ÿ
See the operator manual for your type of tty terminal to find the key sequences
you need to respond to the diagnostics. For the 3151, refer to the 3151 ASCII
Display Station Guide to Operations, form number GA18-2633. For the 3164,
refer to the 3164 ASCII Color Display Station Description, form number
GA18-2617.
Ÿ
When the diagnostics present display information through the S1 port, certain
attributes are used. These attributes are set as if the diagnostics were using a
3161 display terminal. Refer to the tables in Appendix B, “General Attributes
Required When Using a TTY Terminal” on page B-1 for a list of attributes for the
3161 ASCII Display Terminal and for two other ASCII display terminals
commonly used with the system.
Ÿ
If you have a tty terminal other than a 3151, 3161 or 3164 attached to the S1
port, your terminal may have different names for the attributes. Refer to the
Chapter 5. Using the Stand-alone and Online Diagnostics
