In the previous part of this post, we have configured the disks for our Windows Cluster. The disks are created from a RAID 5 LUN. As you can see, we have a LUN of 60GB however only 40GB is available for shared storage.
Now, we have all our disks ready, its time to add it to both our nodes. To begin with, I am going to log on to our first node, BLRC100. Both the nodes will access these shared disk with the iSCSI service available with Windows Server 2008. Open the iSCSI Initiator from the administrative tools (Start Menu –> Administrative Tools –> iSCSI Initiator). If the iSCSI service is not running on this server, you will get the following screen, click on Yes to start the Microsoft iSCSI service on this server.
The iSCSI Initiator properties window will be opened. Click on the Discovery tab. In this tab, we are going to add the storage server portal. Click on Add Portal, and provide the IP address or FQDN of the storage portal and click on OK. If you get the following error message, make sure the iSCSI service is running on the storage server.
Now that we have added the target portal, click on the Targets tab of the iSCSI initiator properties. You will find all the disks in inactive state. Select one disk and click on the Log On button, you will get the following screen. Make sure, you select the checkbox next to Automatically restore this connection when the computer starts. Click on OK to continue. Once you have added some of these disks, you will get the following screen. In the below screenshot, the disks next to the green-line are connected; however the disks next to the red-line are still inactive.
Once all the disks are active, click on the Favorite Targets tab to list all the shared disk available to the Cluster node. Click on Ok to close the iSCSI Initiator properties window. We need to repeat all the above steps on the other node, to make these disks available.
Once you open the Server Manager (Start Menu –> Administrative Tools –> Server Manager) and browse to Storage –> Disk Management. You will find all the disks are available offline. Right-click on the disk, and select Online from the drop-down menu.
After you initialized the disk, format the disk. Make sure you have selected NTFS file system for the disk. Once the disk is formatted, bring it offline. You need to initialized all the available disks, format it with NTFS partition and then bring it offline. After you have completed all the disks, time to log on to the other node.
As we have completed all the above steps on the first node of our windows cluster, time to move to the second node of our cluster system, BLRC101. Shut down the cluster node BLRC100 & start the node BLRC101. On this node, we have to all the iSCSI service as we have done for node BLRC100, bring the disks online. As we have already formatted the disks earlier, we don’t have to format it once again. Once all the disks are online, you will get the following screen.
Since all the disks are ready for cluster installation, we are going to take these disks offline and shutdown this node. Then we are going to add a network adapter on each node, which will create a HeartBeat Network (10.200.41.100/8, 10.200.41.101/8) for the cluster. Once we add the network adapter, we are going to install Dot Net Framework v 2.0 & 3.5 on both the nodes. Since DotNet framework is mandatory for SQL Server cluster installation, we are going to install it before starting the Windows Cluster installation.
As we have installed and configured all the necessary hardware and software, its time to start the windows cluster installation. In the next post, we are going to start the installation of Windows Cluster.
