Cluster operating system preparation

I assume your cluster nodes are all set up; power, network and other cables are connected; the operating system is installed; and disks are partitioned the way you want them. Before you can start with the installation and configuration of the cluster stack software, you must carefully follow these steps:

1. Network configuration: You must configure a static IP address for all available network interfaces on all cluster nodes. You can do this by editing the /etc/sysconfig/network-scripts/ifcfg-ethX files. You must also disable the Network Manager network interface control. In the following screenshot, you can see the network interface configuration for the node-1 cluster node:
   

   Note

   Change the NM_CONTROLLED line to no. This specifies that the Network Manager service cannot control the network interface.

   Change the BOOTPROTO line to none. This specifies that no boot protocol is used for this interface, since this interface has a static IP address assigned to it...
