Hi Akinobu, Can you add optional properties to switch the behavior? For the use case below, the pwm fan should not stop when the device is shutdown by the system reboot. Our platform is BMC that will use a PWM-FAN driver to control the fan on the managed host. In our case, we do not want to stop the fan when the BMC is reboot, which may cause the temperature of the managed host not to be lowered.
