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.
