It looks like you are logging in using the VIP, do not do this, this is only meant for the proxy traffic, not the GUI traffic (though it may work, its not designed for this purpose).
Also, make sure the central managment listener IP's match the physical IP of the appliance.
As far as the appliances acting in active/passive, that is not currently possible (but may be in the future). Is there a reason you really need active/passive? Active/active is on when you have a director priority set for both nodes.
thanks for your response.
can you please provide me with the recommended configuration for the HA in steps, cause i didn't find the required documentation.
regarding the Active-Passive mode.. one of our customers asked me about.
