HA configuration for Viprion2400 with 2250 blades

Hi,

 

i have a pair of viprion 2400 each with a blade of 2250 to be installed in our new environment.

 

i have created one vcmp guest on each of the vcmp host in both the viprions.

 

my question is, do i need to configure the HA just for the vcmp guests and leave the chassis as stand alone or do i need to configure the HA for both the guests and the hosts(chassis).

 

which would be the recommended way of doing. please advice the practice to accomplish this task.

 

Thank you.
