Hi,
I would like to ask about current behavior of phosphor-fan-present.
When I unplug one fan, phosphor-fan-monitor will only update the
Functional Dbus properties of /system/chassis/motherboard/FAN3_1/FAN3_1
and /system/chassis/motherboard/FAN3_1 of inventory interface to false.
But not for "/xyz/openbmc_project/sensors/fan_tach/FAN3_1" of hwmon
interface.
Below is test log:
~# busctl get-property xyz.openbmc_project.Inventory.Manager
/xyz/openbmc_project/inventory/system/chassis/motherboard/FAN4_2/FAN4_2
xyz.openbmc_project.State.Decorator.OperationalStatus Functional
b false
~# busctl get-property xyz.openbmc_project.Inventory.Manager
/xyz/openbmc_project/inventory/system/chassis/motherboard/FAN4_2
xyz.openbmc_project.State.Decorator.OperationalStatus Functional
b false
~# busctl get-property xyz.openbmc_project.Hwmon-1644477290.Hwmon1
/xyz/openbmc_project/sensors/fan_tach/FAN4_2
xyz.openbmc_project.State.Decorator.OperationalStatus Functional
b true
Is this the expected behavior?
Regards.
Thu Nguyen.

Yes. The phosphor-fan-monitor application is configured to only update
the functional status of the fan (and/or individual fan rotors) within
inventory. This is separate than the functional state of the device
providing the tach sensors themselves since, for example, the sensor can
be correctly reporting 0 RPMs for a feedback speed, however that should
be shown as a nonfunctional fan needing to be replaced and not the
device providing the tach sensors of the fan.

It is clear.
Thank Matthew,
