If Panorama is in a suspended state, check for the following conditions:
Verify that the serial number on each Panorama virtual appliance is unique. If the same serial number is used to create two or more instances of Panorama, all instances using the same serial number will be suspended.
Verify that you have set the HA priority setting on one peer as Primary and the other as Secondary. If the priority setting is identical on both peers, the Panorama peer with a higher numerical value in serial number is placed in a suspended state.
Verify that both Panorama HA peers are running the same Panorama version (major and minor version number).
