4.8.7 Configuring the Second Node
Important: For this procedure, have node one and all shared disks
powered on, then power up the second node.
Installation of Cluster Service on the second node takes less time than
on the first node. Setup configures the Cluster Service network settings
on the second node based on the configuration of the first node.
Installation of Cluster Service on the second node begins the same way
as installation on the first node. The first node must be running during
installation of the second node.
