Configure anti-affinity rule and virtual machine group for a clustered vRealize Automation instance

If your vRealize Automation environment is clustered, you can create an anti-affinity rule and machine cluster to ensure proper vSphere High Availability workflow.

To protect any clustered vRealize Automation nodes from a host-level failure, configure an anti-affinity rule to run virtual machines that exist on different hosts in the default vSphere management cluster. After you create an anti-affinity rule, configure a virtual machine group to define the desired machine start-up order. By using a defined machine start-up order, you can ensure that vSphere High Availability powers on the clustered vRealize Automation nodes in the correct order for your environment.
