Explanation

Requirements for a VMware HA Cluster Review this list before setting up a VMware HA cluster. For more information, follow the appropriate cross reference or see Creating a VMware HA Cluster. All hosts must be licensed for VMware HA. You need at least two hosts in the cluster. All hosts need a unique host name. All hosts need to be configured with static IP addresses. If you are using DHCP, you must ensure that the address for each host persists across reboots. All hosts must have access to the same management networks. There must be at least one management network in common among all hosts and best practice is to have at least two. Management networks differ depending on the version of host you are using. ESX hosts - service console network. ESXi hosts earlier than version 4.0 - VMkernel network. ESXi hosts version 4.0 and later - VMkernel network with the Management Network checkbox enabled. See Networking Best Practices. To ensure that any virtual machine can run on any host in the cluster, all hosts should have access to the same virtual machine networks and datastores. Similarly, virtual machines must be located on shared, not local, storage otherwise they cannot be failed over in the case of a host For VM Monitoring to work, VMware tools must be installed. See VM and Application Monitoring. All hosts in a VMware HA cluster must have DNS configured so that the short host name (without the domain suffix) of any host in the cluster can be resolved to the appropriate IP address from any other host in the cluster. Otherwise, the Configuring HA task could fail. If you add the host using the IP address, also enable reverse DNS lookup (the IP address should be resolvable to the short host name).
