Primary FortiGate-6000 selection with override enabled

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
• Number of active SSDs (if SSD failure protection is enabled)
• Device priority
• Age
• 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, both FortiGate-6000s have the same number of failed FPCs, and SSD failure protection is either not enabled or an SSD has not failed. 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.
