Check HA synchronization status

The HA synchronization status can be viewed in the GUI through either a widget on the Dashboard or on the System > HA page. It can also be confirmed through the CLI. When a cluster is out of synchronization, administrators should correct the issue as soon as possible as it affects the configuration integrity and can cause issues to occur.

When units are out of synchronization in an HA cluster, the GUI will compare the HA checksums and display the tables that caused HA to be out of synchronization. This can be visualized on the HA monitor page and in the HA status widget.

HA synchronization status in the GUI

Following HA setup, the HA Status widget can be added to the Dashboard that shows the HA synchronization statuses of the members.

A green checkmark is shown next to each member that is in synchronization.

A member that is out of synchronization is highlighted in red. Hover the cursor over the unsynchronized device to see the tables that are out of synchronization and the checksum values.

You can also go to System > HA to see the synchronization statuses of the members. A member that is out of synchronization will have a red icon next to its name. Hover the cursor over the unsynchronized device to see the tables that are out of synchronization and the checksum values.

HA synchronization status in the CLI

In the CLI, run the get system ha status command to see if the cluster is in synchronization . The synchronization status is reported under Configuration Status.

When both members are in synchronization:

# get system ha status
HA Health Status: OK
Model: FortiGate-VM64
Mode: HA A-P
Group: 0

    <2021/04/29 13:17:03> FGVMEV0000000002 is selected as the primary because its uptime is larger than peer member FGVMEV7000000005.
    <2021/04/29 12:37:17> FGVMEV0000000002 is selected as the primary because it's the only member in the cluster.
