Concept Guide

name=value pair Description
action=powercycl
e
Turns off the electrical power to the system, pauses, turns the power on, and
reboots the system. Power cycling is useful when you want to re-initialize 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:
Table 52. Valid Parameters Of Thermal Shutdown
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 degree Celsius) that exceeds
the maximum temperature warning threshold value.
