I am experiencing the same symptom as was reported in this thread: Create Cluster Wizard in SCVMM 2012 doesn't have IP Address page. However, the resolution posted there doesn't apply in my case as I am adding my nodes to be used by the cluster and the page still doesn't show up. I have tried pre-creating my virtual switches, virtual network adpaters, and static IP addresses from within SCVMM. I have tried not pre-creating the virtual network resources (beyond what is required for my two physical iSCSI adapters to access my storage).
Any thoughts or suggestions?
