To install SQL Server failover cluster we need to have windows cluster configured with a shared disk.

Step 1

If you do not have a windows cluster configured you can create using Hyper-v

Follow the steps in HOW TO CREATE CLUSTER USING HYPER-V to create Domain controller and two member servers which will act as nodes of the cluster.

Once the domain controller and two member servers are created proceed to step 2

Step 2

Once the domain controller and nodes are created install failover cluster feature and create cluster 

To install the failover cluster feature and create a cluster follow the steps in How to install cluster in windows 2008 and windows 2012

Step 3

Once the cluster is created we have to create shared Disk for installing failover aware clustered application like SQL Server.

Follow the steps in ”How to create shared disk using iSCSI Software Target” to create a shared disk using iSCSI target software.


Once shared disk is configured invoke Setup from  SQL server installation media .Make sure the node in which you perform the  installation has shared disk online.


Run the setup.

Start the installation by selecting New SQL Server Failover Cluster Installation option.


Setup support rules will analyze and identify the problems that might occur during setup installation.


After setup validation ,you will get details about operations completed,Click Next and continue


On the Product key page, specify the Product ID key of the product. Click Next.
