Primary unit selection and failover criteria

Once two FortiGate-7000s recognize that they can form a cluster, they negotiate to select a primary chassis.
Primary selection occurs automatically based on the criteria shown below. After the cluster selects the primary,
the other chassis becomes the backup.
Negotiation and primary chassis selection also takes place if the one of the criteria for selecting the primary
chassis changes. For example, an interface can become disconnected or module can fail. After this happens, the
cluster can renegotiate to select a new primary chassis also using the criteria shown below.
