I'm really confused here, and i very well could be missing something. I've just upgraded to 5.5 from 5.1 and started having problems.
I have an issue where vcenter keeps dropping the esxi host, marking it as discconnected, after 60 seconds or so.
i've determined it's because it is not getting a heart beat from esxi host.
running some packet captures i found that the esxi host was not sending the heartbeat on port 902, but for some reason on port 922.
I have installed and reinstalled vcenter multiple times making sure the port entered in the setup is 902.
i have manually edited the /etc/vmware/vpxa/vpxa.cfg and saved it changing the port back then manually restarted the services. Eureka! it starts sending the heartbeat out on port 902... and then i go to vsphere and reconnect to the host and i'm foiled. it reconfigures the vpxa.cfg back to 922 and the heartbeat starts going out on 922. except vcenter is not listening on 922...
HELP I'm at my whits end.
