How to install a Failover Server Cluster

Installing the First Node in the Cluster

When a new cluster is built from scratch, the system on which we start building the cluster the first node in the cluster. After building the first node properly, we can add additional nodes to this cluster. Follow these steps to build the first node. Please remember that the drive "Q" is not a local drive, but it is a remote storage (image file based iSCSI target created using StarWind software. In this example, the drive "Q" is going to be our quorum disk.

1) Shut down both the cluster nodes and and make sure that the iSCSI target server (on which you have installed StarWind software and image file based device) is up and running.

2) Power on the first node, and make sure that the remote iSCSI device which is going to hold the cluster quorum database is mounted as local drive "Q" by using the Microsoft iSCSI Initiator.

3) This node should be a member of Active Directory Domain, it this node is not a member of Active Directory Domain, add this node to domain.

4) Configure network cards in each node with the correct TCP/IP configuration settings. Private network card, which is used only for the cluster communication should have only an IP address and subnet mask configured. Default Gateway, DNS, and WINS should not be configured. Remember to uncheck the Register This Connection's Address in DNS box in TCP/IP properties dialog box.

5) Create a service account in Active Directory for the cluster service. Here I have created an account in Active Directory, "clustuser", using "Active Directory Users and Computers snap-in".

6) Open the Cluster Administrator GUI Tool (Start > Programs> Administrative Tools > Cluster Administrator). Select create new cluster from the combo box, and click "OK".
