Unable to build a cluster when sharing the same network for iSCSI Storage

In this blog post we will look at an issue relating to sharing the same iSCSI Storage network for cluster communication. Looking at networking best practices for creating a Windows Server 2012 Failover Cluster, it is recommend that we separate iSCSI storage traffic from Cluster Communication. iSCSI needs to be on a separate dedicated network and it is not recommended to share iSCSI Storage Trafic & Network communication traffic. At the time of cluster being created, it will automatically disable the network for cluster communication if it is used for iSCSI Storage traffic and this will cause the cluster creation to fail.
