2 Power on all of the cluster units.
As the cluster units start, they negotiate to choose the primary unit and the
subordinate units. This negotiation occurs with no user intervention and normally just
takes a few seconds.
You can now configure the cluster as if it is a single FortiGate unit.
To add a new unit to a functioning cluster
1 Configure the new cluster unit for HA operation with the same HA configuration as the
other units in the cluster.
2 If the cluster is running in Transparent mode, change the operating mode of the new
cluster unit to Transparent mode.
3 Connect the new cluster unit to the cluster.
4 Power on the new cluster unit.
When the unit starts it negotiates to join the cluster. After it joins the cluster, the cluster
synchronizes the new unit configuration with the configuration of the primary unit.
To configure weighted-round-robin weights
By default, in active-active HA mode the weighted round-robin schedule assigns the
same weight to each cluster unit. From the CLI you can use the following command to
configure a weight value for each cluster unit.
