thermal-health-check

Syntax

Hierarchy Level

Description

Enable thermal health check, and configure an action to be taken on detection of a thermal health event such as power leakage. The thermal check feature monitors the PSM power output and FRU power consumption and if it detects that the PSM power output exceeds the FRU power consumption by a user-defined threshold, it assumes that there is a thermal health event, and takes an action based on the user configuration.

Use fet-failure-check option to shutdown the PSM, raise a Field-effect Transistor (FET) failure alarm and log the events.

Chassis shuts down when power drawn is more than threshold, three times consecutively.

Options

fet-failure-check Enable FET failure detection, and configure an action to be taken upon FET failure.
action-onfail Choose an action to be performed on detection of a thermal health event. The following options are available:
  • auto-shutdown—The software shuts down the system when a thermal health event is detected.

  • none—The software raises a major alarm when a thermal health event is detected.

shutdown-timer value Duration (in seconds) after which the system is shut down on detection of a thermal health event, if auto-shutdown is set as action-onfail.
  • Range: 10 through 900 seconds

  • Default: 900 seconds

power-threshold value Power leak threshold (in watts) considered for the configured action to be taken. This means the configured action is taken if the power leak exceeds by the value configured here (or if the PSM output power exceeds the FRU power consumption by the set threshold value).
  • Range: 600W through 1000W

  • Default: 600W

Example

The following command enables thermal health check, and shuts down the system after 10 seconds of thermal health check failure.
