The object properties added at the end of the object name are referred to as trailers. The overall health status of the host can be changed correctly in some scenarios, but the hardware item health status will not be updated in OpsMgr. Most often the health state of the affected hardware item may be "Unknown" (grey) in VMware vSphere client.
