Select an HA mode for the cluster or return the FortiGate units in the
cluster to standalone mode. When configuring a cluster, you must set all
members of the HA cluster to the same HA mode. You can select
Standalone (to disable HA), Active-Passive, or Active-Active. If virtual
domains are enabled you can select Active-Passive or Standalone.
Optionally set the device priority of the cluster unit. Each cluster unit can
have a different device priority. During HA negotiation, the unit with the
highest device priority usually becomes the primary unit.
In a virtual cluster configuration, each cluster unit can have two device
priorities, one for each virtual cluster. During HA negotiation, the unit
with the highest device priority in a virtual cluster becomes the primary
unit for that virtual cluster.
Changes to the device priority are not synchronized. You can accept the
default device priority when first configuring a cluster. When the cluster
is operating you can change the device priority for different cluster units
as required.
