Using SystemGuard
2-11
When the system is in Stand-By mode and the System Key (Physical or Electronic Key) is in
Service mode, the STAND-BY MENU can be accessed and SystemGuard executed.
If you turn the system unit power on from Stand-By mode with the System Key in the Normal
position, the system boots to AIX Multi-User.
If you turn the system unit power on with the System Key in the Service position, you can go
to the MAINTENANCE MENU or to Diagnostics, depending on the state of three flags:
SystemGuard Console Present, Autoservice IPL, and Service Contract Validity.
If you power on the system with the System Key in Secure, the system stalls.
Here is some information on the meaning of the different flags:
BUMP Console Present flag
When the BUMP console is enabled, the LED codes and System Guard
messages are displayed on the console during the Init phase. If the BUMP
console is not enabled, it is like a regular system; no codes and no
messages are displayed on the console during the Init phase. Only AIX
messages appear when the system starts loading AIX.
Note that if you are running the level 5 of the SystemGuard firmware, the
BUMP Console is disabled by default, and if you enable it, it is disabled after
every shutdown. If your system is in Service mode, you might go to
Diagnostics instead of Maintenance due the SystemGuard Console being
disabled by default.
If you are running level 7 or higher of the SystemGuard firmware, the BUMP
Console is enabled by default and stays enabled after a shutdown.
Autoservice IPL flag
If enabled, this flag means that you want to go to Diagnostics when booting
with the System Key in Service mode.
Service Contract flag
This flag is preset at the factory and is not variable. The Service Contract is
always valid. This flag allows the service center to access the system and
do some maintenance. The Service Contract is set by default to an
unlimited number of days (exactly 32767 days).
SystemGuard Menus
SystemGuard menus are low-level menus; they make extensive use of abbreviations or
acronyms. Refer to the glossary on page X-1 for a full list of these acronyms and
abbreviations.
SystemGuard is menu-driven, and menu choices are usually numbered. Letters are
sometimes used and can be entered in either lowercase or uppercase (SystemGuard is
case insensitive). The letter
x
is often used to exit the current menu and return to the
previous menu (or leave SystemGuard, if given from the main menu). Commands are only
treated after you press the Enter key. Until you press the Enter key, you can use the
Backspace key to edit a command. If you enter a command that does not match the
available options, a beep signals that an invalid selection has been made.
