In previous steps, we have completed the following:

-2 Windows 2008 R2 Hyper-V servers (LAB-HVCORE-01 and LAB-HVCORE-02)
-Attached to a couple of 300GB iSCSI LUNs hosted on EMC Storage.
-Created the initial External virtual network on each Hyper-V host using Hyper-V Manager.

Here are the links to the previous posts:

Part 1 – Creating a Windows Server 2008 R2 Hyper-V Failover Cluster: Install Hyper-V and Failover Clustering
Part 2 – Creating a Windows Server 2008 R2 Hyper-V Failover Cluster: Configuring iSCSI Connectivity
Part 3 – Creating a Windows Server 2008 R2 Hyper-V Failover Cluster: Hyper-V Virtual Networking

In this step, we will run the Cluster Validation Wizard to ensure our Hyper-V servers and storage setup is capable of supporting a Windows failover cluster.

1. Launch the Failover Cluster Management console (again, from a machine with the RSAT tools or a 2008 R2 Server) and under Actions, click Validate a Cluster.

2. Click Next on the Before you Begin screen.

3. On the Select Servers of a Cluster screen, at Enter Name, add each Hyper-V server and click Add. Click Next to continue.

4. On the Testing Options screen, select Run All Tests and click Next.

5. On the Confirmation screen, click Next to begin the validation tests.

6. On the Summary screen, review the results on the cluster validation wizard and click Finish.

Review any warnings and correct any failures you may see. In Part 5, we’ll build the failover cluster.
