ESX host may become unresponsive with the error: BMC returned incorrect response, expected netfn 7 <cmd>, got netfn 7 <cmd>
Symptoms
" You see the following error on the console or in /var/log/messages:
BMC returned incorrect response, expected netfn 7 <cmd>, got netfn 7 <cmd>
" ESX host may become unresponsive
Resolution
This issue may occur if the BMC controller requires a firmware update. Many vendors provide firmware for their BMC controllers separately from the system BIOS/firmware upgrades. To resolve this issue, apply the BMC specific firmware updates. These updates stop messages from being written to the log and prevents the server from reaching a point where a lock up occurs.
If applying the firmware updates does not resolve the issue, verify that the appropriate version of the 3rd party management agents are installed. If the correct versions are installed, briefly disable them as a diagnostic step. If this does not resolve the issue, engage your hardware vendor to determine if there is an issue with the BMC controller itself.

BMC means Baseboard Management Controller.
I think this issue is specific to the Hardware and not with respect to VMware.
Have you checked with HP Website for any pertinent issues ?
