To view cluster status
As you add units to the cluster you can log into the CLI of one of the cluster units using its reserved management interface to view the status of the cluster. The status will show each unit as it is added to the cluster.
For example, the following command output shows the status of the cluster when all three cluster units have been added:
get system ha status Model: FortiGate-5001C Mode: a-a
Group: 0
Debug: 0
ses_pickup: disable
Master:128 slot-5 FG-5KC3E13800084 0
Slave :128 slot-4 FG-5KC3E13800051 1
Slave :128 slot-3 FG-5KC3E13800046 2 number of vcluster: 1
vcluster 1: work 169.254.0.1
Master:0 FG-5KC3E13800084
Slave :1 FG-5KC3E13800051
Slave :2 FG-5KC3E13800046
You can use this command to confirm that the cluster is operating normally. For example, if the command shows only two cluster units then one unit has left the cluster for some reason.
To troubleshoot the cluster
See FortiGate-5000 active-active HA cluster with FortiClient licenses on page 1385.
To manage each cluster unit
Because you have configured a reserved management interface, you can manage each cluster unit separately by connecting to the IP address you configured for each unit’s mgmt1 interface. You can view the status of each cluster unit and make changes to each unit’s configuration. For example, as described below, each cluster unit must have its own FortiClient license. You can use the reserved management IP addresses to connect to each cluster unit to install the FortiClient license for that unit.
Usually you would make configuration changes by connecting to the primary unit and changing its configuration. The cluster then synchronizes the configuration changes to all cluster units. If you connect to individual cluster units and change their configuration, those configuration changes are also synchronized to each cluster unit. The exception to this is configuration objects that are not synchronized, such as the host name, FortiClient license and so on.
You can also manage each cluster unit by logging into the primary unit CLI and using the following command to connect to other cluster units:
execute ha manage <cluster-index>
