A. Creating a cluster in Server 2008 using the cluster.exe command follows essentially the same process as creating a cluster by using the Microsoft Management Console (MMC) Failover Cluster Management snap-in. The process essentially consists of telling the Create Cluster Wizard the nodes that will be in the cluster and then the network name and static IP address (if dynamic IP isn’t used on the NICs).
Before you attempt to create a Server 2008 cluster, you need to install the Server 2008 Failover Clustering feature. If you’re running Server Core, you’d use the following command to install failover clustering:
start /w ocsetup FailoverCluster-Core
On a full Server 2008 installation, you can install failover clustering by running this command:
servermanagercmd -install Failover-Clustering
(Of course, you can also use the MMC Server Manager snap-in to install features, but here we’re concentrating on the command line.) To create a Server 2008 cluster from the command line, run cluster.exe using the following format:
cluster /cluster:<netname for cluster> /create /nodes:"node1> <node2>" /ipaddress:<IP address>/<subnet mask>
Here’s a cluster.exe command example and its ouput:
C:\>cluster /cluster:savdalclusfs01 /create /nodes:"savdalclus01 savdalclus02" /ipaddress:192.168.1.105/255.255.255.0

When you create a cluster at the command line, disk resources are not added automatically and Node Majority will be used as the quorum mode. I’ll discuss how to add disk resources in the next FAQ, "Q. How can I add disk resources to a Windows Server 2008 cluster from the command line?"
The screencast below takes you through using the command line to perform this and other Server 2008 cluster-configuration tasks.
