Many FortiGate platforms have gone through multiple hardware versions and in some cases these hardware changes might prevent cluster formation. If you run into this problem, you can use the following command on each FortiGate to set the cluster to ignore different hardware versions:
execute ha ignore-hardware-revision enable
This command is only available on FortiGates that have had multiple hardware revisions. If this command isn’t available, then hardware version issues should not prevent cluster formation.
By default the command is set to prevent cluster formation between FortiGates with different hardware revisions. You can enter the following command to view its status:
execute ha ignore-hardware-revision status
Usually the incompatibility is caused by different hardware versions having different hard disks. Enabling this command disables each FortiGate’s hard disks. As a result of disabling hard disks, the cluster will not support logging to the hard disk or WAN Optimization.
If the FortiGates have compatible hardware versions or if you want to run a FortiGate in standalone mode, enter the following command to disable ignoring the hardware revision and enable hard disks:
execute ha ignore-hardware-revision disable
Affected models include but are not limited to:
- FortiGate-80C and FortiWiFi-80C
