Hi Mike,

 

 

I actually avoid using state preference setting as it will result in an extra failover if the preferred active unit fails and then comes back up.

 

 

Do the units have connectivity to the same management network? Have you configured the peer management address for each unit under System >> High Availability >> Network Failover?

Also, are the units physically close enough (50 feet) to use hardwire failover? If so, this is a faster failover mechanism than network failover.
