FortiManager HA Failover Inquiry

[FXE]

Hi Guys,

I am a bit new in the FMG world.

I would like to ask the following regarding HA for FMG,

[ol]

In FMG VM HA environment, can I just have 1 interface for each of my FMG VM that will be holding my data and HA hearbeat/synchronization?

I have a setup that I have 1x FMG in Site-A (FMG-A) and Site-B (FMG-B) then these FMG will be in HA. All of the FortiGates either in Site-A and Site-B will be managed by this FMG. In the disaster recovery event that the Site-A will go down, the FMG cluster will now be down so I need to promote the FMG-B to be the new master. My question now are these,[ul]

The FMG-A will still be the master once Site-A goes up again, correct?

If the FMG-A is still the master, what will happened to the FMG-B that I promoted to become the master during the disaster recovery event?

Do I need to make the FMG-A to be slave first before Site-A goes up, so that it will look for the new master which is the FMG-B?[/ul][/ol]

Thank you so much for the help.
