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 4-30. 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.
