We have a ESXi 5.0.0 (469512) installation on a Cisco R200-1120402W and used the Cisco customized ISO installation media. Primary issue is that serial port passthrough is not working. The only thing that I notice is different about this vmWare install than others we have is that the health status sensors in Configuration are all "Unknown".
Everything else about the server works fine. Any thoughts or confirmation about the sensors being related to the issue or better yet, what we can do to resolve or steps we can take to get more detail on the root cause?
