Hi, I have gone through documentation and started testing HA in my kvm environment, I stopped the agent and now the ha state changes from suspect to degraded and stays in degraded state and never recover or fence the host, can someone help me on this and let me know is this expected or how to further test why this is been in degraded state and host power state is in on and state is in disconnected.
