TABLE 6-2OpenBoot Configuration Variables (Continued)

OpenBoot Configuration

 

Variable

Description and Keywords

diag-triggerSpecifies the class of reset event that causes diagnostic tests to run. This variable can accept single keywords as well as combinations of the first three keywords separated by spaces. For details, see “How to View and Set OpenBoot Configuration Variables” on page 180. Default is power-on-resetand error-reset.

•error-reset—Reset that is caused by certain hardware error events such as RED State Exception Reset, Watchdog Reset, Software-Instruction Reset, or Hardware Fatal Reset.

•power-on-reset—Reset that is caused by power cycling the system.

•user-reset—Reset that is initiated by an operating system panic or by user- initiated commands from OpenBoot (reset-allor boot) or from Solaris (reboot, shutdown, or init).

•all-resets—Any kind of system reset.

•none—No power-on self-tests or OpenBoot Diagnostics tests run.

input-deviceSelects where console input is taken from. Default is keyboard.

•ttya—From built-in serial port.

•keyboard—From attached keyboard that is part of a graphics terminal.

•rsc-console—From the system controller.

Note: Should the specified input device be unavailable, the system automatically reverts to ttya.

output-deviceSelects where diagnostic and other console output is displayed. Default is screen.

•ttya—To built-in serial port.

•screen—To attached screen that is part of a graphics terminal.

•rsc-console—To the system controller.

Note: POST messages cannot be displayed on a graphics terminal. They are sent to ttya even when output-deviceis set to screen. Should the specified output device be unavailable, the system automatically reverts to ttya.

service-mode?Controls whether the system is in service mode. Default is false.

•true—Service mode. Diagnostics are executed at Sun-specified levels, overriding but preserving user settings.

•false—Normal mode, unless overridden by the system control switch. Diagnostics execution depends entirely on the settings of diag-switch?and other user- defined OpenBoot configuration variables.

Note: If the system control switch is in Diagnostics position, the system will boot in service mode even if the service-mode?variable is false.
