Omconfig System Shutdown Or Omconfig Servermodule
Shutdown
Use the omconfig system shutdown or omconfig servermodule shutdown command to determine how the system shuts
down. During system shutdown, the default is to shut down the operating system before powering off the system. Shutting down the
operating system first closes down the file system before powering the system down. If you do not want to shut down the operating
system first, use the osfirst=false parameter.
NOTE: The parameter osfirst=false is not available on 13th generation and later systems. By default, on 13th
generation and later systems, the operating system shuts down before turning off the server during a remote
shutdown.
The following table displays the valid parameters for the command.
Table 76. Valid Parameters Of System Shutdown
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 off the electrical power to the system.
action=powercycle Turns off the electrical power to the system, pauses, turns on the power, 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 turning off the server.
false: Does not close the file system or shuts down the operating system before turning off the server.
NOTE: This command osfirst=false is not available on 13G and later systems. By default, on
13G and later systems, the operating system shuts down before turning off the server during a
remote shutdown.
Example Shutdown Commands
To set the shutdown action to reboot, type:
omconfig system shutdown action=reboot
or
omconfig servermodule shutdown action=reboot
To bypass operating system shutdown before the system is powered off, type:
omconfig system shutdown action=reboot osfirst=false
or
omconfig servermodule shutdown action=reboot osfirst=false
NOTE:
The parameter osfirst=false is not available on 13G and later systems. By default, on 13G and later systems,
the operating system shuts down before turning off the server during a remote shutdown.
Omconfig System Thrmshutdown Or Omconfig
Servermodule Thrmshutdown
Use the omconfig system thrmshutdown or omconfig servermodule thrmshutdown command to configure a thermal
shutdown action. You can configure the system for a thermal shutdown when a temperature probe detects a temperature probe warning
or failure event.
The following table displays the valid parameters for the command:
