Table 76. Valid Parameters Of System Shutdown (continued)
name=value pair Description
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 YX3X and later systems. By default,
on YX3X 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 YX3X and later systems. By default, on YX3X 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 77. 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.
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 degree Celsius) that exceeds the maximum temperature failure
threshold value.
