Determining the primary FPM
You can determine which FPM is operating as the primary (master) FPM by hovering over the FPMs in the Security Fabric dashboard widget. The FPM operating as the primary FPM will have a Status of Master Blade.
You can also use the diagnose load-balance status command to determine which FPM is operating as the primary FPM.
The following example diagnose load-balance status output for a FortiGate-7060E showing that the FPM in slot 3 is the primary (master) FPM. The command output also shows the status of all of the FPMs in the FortiGate-7060E. The output also shows that the FPM in slot 4 is either missing or down.
