14 Preparing Your Systems for Clustering
5 Configure each server node as a member server in the same
Windows Active Directory Domain.
NOTE: It may also be possible to have cluster nodes serve as Domain
controllers. For more information, see “Selecting a Domain Model”.
6 Establish the physical storage topology and any required storage network
settings to provide connectivity between the storage array and the servers
that will be configured 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 cluster quorum disk for Windows
Server 2003 Failover cluster and as a witness disk for Windows Server 2008
Failover cluster. Ensure that this LUN is presented to the servers that will
be configured as cluster nodes.
NOTE: It is highly recommended that you configure the LUN on a single node,
for security reasons, 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
cluster nodes can access it.
8 Select one of the servers and form a new failover cluster by configuring the
cluster name, cluster management IP, and quorum resource.
NOTE: For Windows Server 2008 Failover Clusters, 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.
10 Configure roles for cluster networks. Take any network interfaces that are
used for iSCSI storage (or for other purposes outside of the cluster) out of
the control of the cluster.
11 Test the failover capabilities of your new cluster.
NOTE: For Windows Server 2008 Failover Clusters, the Cluster Validation
Wizard may also be used.
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.
13 Configure client systems to access the highly-available applications and
services that are hosted on your failover cluster.
