Consider the following scenario:
You have a Windows Server 2012-based failover cluster.
A Hyper-V server role is installed on the cluster node.
You create a virtual machine on the cluster node, and then you configure the virtual machine as a cluster resource.
You add a pass-through disk to the virtual machine by using Windows Management Instrumentation (WMI).
In this scenario, the virtual machine does not come online.
Note If you add the pass-through disk by using the Failover Cluster Management snap-in, the virtual machine does come online.
