Hi Jakov Thank you for your response. My two hosts have multiple network interfaces or ethernet cards. I understood from your email, that the IP corresponding to "cluster node name" for both hosts, should be in the same subnet before a cluster could bring virtual IP up. I will reconfirm if these are in same subnets.
