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.)
Here we are using Windows Server 2008 R2 Enterprise hosts, with HP LeftHand/P4000 iSCSI Storage.
The guide is split into 4 parts:
Part 3: Cluster Shared Volume
Note: CSV is only available with a cluster of all 2008R2 Hyper-V hosts and above!
In Failover Cluster Manager - right-click the Cluster object, and click Enable Cluster Shared Volumes…
This makes a new folder object appear in the tree:
Right-click the ‘Cluster Shared Volumes’ folder > and click ‘Add storage’
And choose the disk(s) you want to use as your CSV!
