  1. Use the HA Group feature to control what triggers failover of your traffic-group, such as pool monitors.
  2. Not really (well, I can think of a quite perverse way - but don't do it). Your HA Group configuration should include monitoring of the gateways as well as the nodes. If you want to be able to survive the scenario that link failures mean one appliance can reach one node, the other can reach the other node, but neither can reach both - then the answer is to use HA and configure two traffic-groups. Put the two VIPs into the different traffic-groups, create two different HA groups each monitoring the relevant node, and associate one HA group with one traffic-group.
