Honestly I don’t see the point of your message, you basically show the same as i did, unless the fact that you have tree servers in your cluster, my servers are hosted so i’m very sorry but I can’t pull or plug a cable…

Yes in this configuration, i only have a two hosts cluster and I know it is not made for activate HA that’s why i do not.

And as far as I know I didn’t blamed anyone so I don’t understand the tone of your mail. (saying hi, thank or regards doesn’t hurt i assure you) 
I’m seriously wondering about buying subscription with support level and you’re not helping me... 

Regards,
