I have a Windows 2012 Hyper-V Cluster with 2 Nodes. They have a connecting to SAN via FC and have 3 disk - Qourum and 2 CSV. I'm connected 3rd node to san and domain, install hyper-v role, updates, mpio. In disk management i see all 3 disk, status offline.
Whether it is necessary to online this disk or i can add node to cluster?
