98 omconfig: Managing Components Using the Instrumentation Service
Example Shutdown Commands
To set the shutdown action to reboot, type:
omconfig system shutdown action=reboot
To bypass operating system shutdown before the system is powered off, type:
omconfig system shutdown action=reboot osfirst=false
omconfig system thrmshutdown
Use the omconfig system thrmshutdown command to configure a thermal shutdown action. A thermal
shutdown can be configured to occur when a temperature probe detects a temperature probe warning or
failure event.
Table 4-30 shows the valid parameters for the command.
Table 4-29. Shutdown Parameters
name=value pair Description
action=reboot Shuts down the operating system and initiates system startup, performing BIOS checks
and reloading the operating system.
action=poweroff Turns the electrical power to the system off.
action=powercycle Turns the electrical power to the system off, pauses, turns the power on, and reboots the
system. Power cycling is useful when you want to reinitialize system components such as
hard drives.
osfirst=true | false true: Closes the file system and exits the operating system before shutting down the
system.
false: Does not close the file system or shut down the operating system before shutting
down the system.
Table 4-30. Thermal Shutdown Parameters
name=value pair Description
severity=disabled | warning | failure disabled: Disable thermal shutdown. An administrator must intervene.
warning: Perform a shutdown when a temperature warning event is
detected. A warning event occurs when any temperature probe inside a
chassis reads a temperature (in degrees Celsius) which exceeds the
maximum temperature warning threshold.
failure: Perform a shutdown when a temperature failure event is
detected.
A failure event occurs when any temperature probe inside a chassis reads
a temperature (in degrees Celsius) that exceeds the maximum
temperature failure threshold.
