An HA virtual cluster can be set up using the GUI or CLI.

This example uses the following network topology:


HA virtual clusters are based on VDOMs and are more complicated than regular clusters.


The root VDOM can only be associated with virtual cluster 1.

The VDOM that is assigned as the management VDOM can also only be associated with virtual cluster 1.

To set up an HA virtual cluster using the GUI:
  1. Make all the necessary connections as shown in the topology diagram.
  2. Log into one of the FortiGates.
  3. Go to System > HA and set the following options:



    Device priority
