In cluster environment for the disk resources that are need to be accessed by the SQL service on the cluster, you need to define a "resource" on the cluster. In your case, if I'm not misunderstood your question, you need to define two "resources" on you cluster as D and E so these partitions will be accessible for SQL Service on the cluster.
PS: please do not post in several places in the forum.
