Setup LAB: 06 Installing Windows Failover Cluster to setup AlwaysOn


In the last post, I had configured the iSCSI target service to share the disk between two servers. I am going to use those two servers as Windows server Failover Cluster nodes and setup AlwaysOn availability group using that.

To begin with, I initialized the disk on one server using Computer Management, brought it online, formatted with NTFS partition and assign a drive letter (Q) before taking it offline. On the other server, I brought the disk online to test that the disk is accessible on both the server.

To configure AlwaysOn, both the servers, Node01 and Node02, should be part of the same Windows Server Failover Cluster. I have installed the Failover Cluster role on both of these servers and configured a heartbeat network between these two servers. Open Failover Cluster Manager from the Tools menu in Server Manager to start the failover cluster Validate Configuration wizard. This will check whether the all the necessary pre-requisites are met to begin the failover cluster installation.

Once the validation completed successfully, click the checkbox next to Create the cluster node using the validated nodes to start the failover cluster installation. Make sure, the account you are using to install this Failover Cluster should have Create Computer Object and Read all Properties permissions on the OU. To minimize the future effort, I have created a user group, which will have the above permissions on the OU and added my account to the above group. In case, you are pre-staging the Failover Cluster Name in the AD, you should have Enable Computer Object permission.

Once the Failover Cluster created successfully, I have performed failover to test that the failover is working fine. Next, I am going to install stand-alone SQL Server instance on each of the cluster nodes, Node01 and Node02. The installation of SQL Server will be performed using slip-stream method (more on that later). Once the installation is completed, in the next part, I will start the AlwaysOn Configuration.

Happy Learning Smile !!!
