Clustering Windows Server 2008 R2 Hyper-V Hosts - Part 3/4: Cluster Shared Volume

This step-by-step walkthrough runs through configuring Hyper-V R2 hosts with iSCSI shared storage and using Failover Cluster Manager with CSVs (Clustered Shared Volumes.)

Right-click the ‘Cluster Shared Volumes’ folder > and click ‘Add storage’

And choose the disk(s) you want to use as your CSV!
