Query about ICMP in GCO

Hi  Mates,

 

I just want to know how will the cluster know about the service group status in remote cluster.

I know it will be by the use of ICMP adnd wac process.

But , I am confused with below output of hastatus -summ from one site. when secondary site is isolated due to network/router issue.

 

hastatus -sum

When ICMP is showing down, howcome its still seeing the status of remote cluster and remote service groups.

 

 

Regards

S

 

  • Is it still showing the summary like this or has it changed to OFFLINE for the remote resources?

      Hi,

       

      ICMP is alive and ok now.

      But I need to understand when ICMP is  showing down here , it means heartbeat between two cluster shuld be down .

       

      then what should be the status of remote cluster and service groups in haststus -summ

        - Correct/   

        then what should be the status of remote cluster and service groups in haststus -summ

        - Unknown   or

        - Exited if the remote cluster was gracefully shutdown   or

        - Faulted if the rebote cluster was doen due to failure
