The cluster name can be myclusterand the cluster SCANname can be mycluster-scan.Click Next.The Cluster Node Information window appears.6.In the Public Hostname column of the table of cluster nodes, you should see yourlocal node, for example node1.example.com.The following is a list of additional information about node IP addresses:•For the local node only, OUI automatically fills in public and VIP fields.

If you provide adomain in the address field during installation, then OUI removes the domainfrom the address.•Interfaces identified as private for private IP addresses should not beaccessible as public interfaces. Using public interfaces for Cache Fusion cancause performance problems.•When you enter the public node name, use the primary host name of eachnode. In other words, use the name displayed by the /bin/hostnamecommand.a.Click Addto add another node to the cluster.b.Enter the second node's public name (node2), and virtual IP name (node2-vip), then click OK. Provide the virtual IP (VIP) host name for all clusternodes, or none.You are returned to the Cluster Node Information window. You should nowsee all nodes listed in the table of cluster nodes.c.Make sure all nodes are selected, then click the SSH Connectivitybutton atthe bottom of the window.
