Consider the following scenario:
- You create some failover cluster nodes on computers that are running Windows Server 2012.
- You have the Hyper-V server role installed on the cluster nodes.
- You create virtual machines on one cluster node, and you configure the virtual machines as cluster resources.
- You create multiple Cluster Shared Volume (CSV) resources and create one Virtual Hard Disk (VHD) file in each CSV.
- You use Hyper-V Manager to try to add the VHD files to the virtual machines.
