26 Preparing Your Systems for Clustering
5 Configure each cluster node as a member in the same Microsoft Windows
Active Directory Domain.
NOTE: You can configure the cluster nodes as Domain Controllers. For more
information, see the “Selecting a Domain Model” section of Dell Failover
Clusters with Microsoft Windows Server 2008 Installation and
Troubleshooting Guide at support.dell.com/manuals.
6 Establish the physical storage topology and any required storage network
settings to provide connectivity between the storage array and the systems
that you are configuring as cluster nodes. Configure the storage system(s)
as described in your storage system documentation.
7 Use storage array management tools to create at least one logical unit
number (LUN). The LUN is used as a Witness disk for Windows Server
2008 Failover cluster. Ensure that this LUN is presented to the systems
that you are configuring as cluster nodes.
NOTE: For security reasons, it is recommended that you configure the LUN on
a single node as mentioned in step 8 when you are setting up the cluster.
Later, you can configure the LUN as mentioned in step 9 so that other nodes in
the cluster can access it.
8 Select one of the systems and form a new failover cluster by configuring
the cluster name, cluster management IP, and quorum resource. See
"Preparing Your Systems for Clustering" on page 25.
NOTE: For Failover Clusters configured with Windows Server 2008, run the
Cluster Validation Wizard to ensure that your system is ready to form the
cluster.
9 Join the remaining node(s) to the failover cluster. See "Preparing Your
Systems for Clustering" on page 25.
10 Configure roles for cluster networks.
11 Test the failover capabilities of your new cluster.
NOTE: For Failover Clusters configured with Windows Server 2008, you can
also use the Cluster Validation Wizard.
12 Configure highly-available applications and services on your Failover
Cluster. Depending on your configuration, this may also require providing
additional LUNs to the cluster or creating new cluster resource groups.
Test the failover capabilities of the new resources.
