CUBE HA Behavior ISR-G3

Have a scenario with Cube HA.   The switch the control interfaces reside on went down and as a result both Cube’s reloaded.  I believe this is expected behavior based on the control interfaces going down.   Once the Cube’s came back both went into an Active State with Peer Role disabled.   Again I believe that is expected behavior if control interfaces are still down.  However the Cubes didn't seem to renegotiate HA once the control interfaces came back up. At that point we shut down Secondary Cube to stabilize things.    After some time (days) we powered the second Cube back up HA negotiated and all is back to normal.   Should the Cube's normally renegotiate HA when in the Active Peer Disable state when the control interfaces come back up or do we need another reboot of one of the Cubes to kickstart HA?
