Were having problems in our implementation on vmware HA. 

Our objective is to trigger HA when network failures occurs. 

Here is our Setup:
 
2 esx server and both server has 4 nic cards attach, and we teamed 2 nics for
the SC with 10.236.9.x IP with the default gateway of 10.236.9.1 vlan 9 and for
the vkernel the IP is 192.168.0.x without default gateway vlan 192. The other 2
nics are teamed for the vmnetwork vlan 9 only both esx  server has an IP of
192.168.0.x and it is assigned for vmotion only.

Here is our Test Scenario:

1.When we shutdown esx server (clean shutdown) that has a vmguest the HA was
triggered and migration is successful.

2.Push the power off button(unclean shutdown) that has a vmguest the HA was
triggered and migration is successful.

3.When we tried to unplug 2 -all network cable of esx host that has a vmguest
inside the HA are not triggered. 

Here is the questions sir,

Is there s something wrong with our configuration? I also add the hostname to
etc hosts of both esx for them to able to see each other thru hostname.

Is there particular port or nic to trigger the HA?

Do we need to add other IP address or default gateway of vkernel for the host
to detects when it is isolated on the network?

Do vkernel is the hearbit of HA or sc use to detect also if the host is
isolated on the network.

Why the shutdown testing working and the network failure is not. We tried to
unplug all the cables attached and itsjust like system failures occurs because
they don t receive heartbits. 

Hope somebody help us and give us the proper configuration on vmware network
configuration for HA.


Thank you very much.
