Issue

On an HP c7000 enclosure when one fan unit is pulled out, we observe spurious events unrelated to that unit in the openhpi logs.

When pulling out the FAN unit number one from an HP c7000 blade enclosure we can see the following event in the openhpi logs:

Event Type: HOTSWAP
From Resource: {SYSTEM_CHASSIS,8}{COOLING_UNIT,1}{COOLING_DEVICE,2}{FAN,1}

At the same time we also observe errors related to another FAN unit:
