I should also add some info about my ESX servers.
Both ESX4i and 5i are discovered and inventoried. I can see them under Devices -> ESX and the hardware/firmware information is populated. But neither shows up under manage -> system update.
They don't show up as compliant, needs updates (both do) or even non-inventoried.
Using esxcli I have verified the VIB is installed.
Also with ESX5i with VIB 7.2 installed I can't log in with the managed system login. It just says "page cannot be displayed"
Thanks
