With override enabled, FortiGate-6000 FGCP selects the primary FortiGate-6000 based on standard FGCP primary unit selection with override enabled and also accounting for the number of failed FPCs. The selection sequence is:
- At least one active FPC
- Connected monitored interfaces
- Number of active FPCs
- Device priority
- Serial number
Enabling override and adjusting the device priority means that the FortiGate-6000 with the highest device priority becomes the primary FortiGate-6000 as long as monitored interfaces are not configured, no monitored interface has become disconnected, and both FortiGate-6000s have the same number of failed FPCs. Enabling override causes the cluster to negotiate more often to make sure that the FortiGate-6000 with the highest device priority always becomes the primary FortiGate-6000.
