About the VCS configuration file main.cf
The VCS configuration file /etc/VRTSvcs/conf/config/main.cf is created during the installation process.
The main.cf file contains the minimum information that defines the cluster and its nodes. In addition, the file types.cf, which is listed in the include statement, defines the VCS bundled types for VCS resources. The file types.cf is also located in the directory /etc/VRTSvcs/conf/config after installation.
Note the following information about the VCS configuration file after installing and configuring VCS:
The cluster definition includes the cluster information that you provided during the configuration. This definition includes the cluster name, cluster address, and the names of users and administrators of the cluster.
Notice that the cluster has an attribute UserNames. The installvcs program creates a user "admin" whose password is encrypted; the word "password" is the default password.
If you set up the optional I/O fencing feature for VCS, then the UseFence = SCSI3 attribute that you added is present.
If you configured the cluster in secure mode, the main.cf includes the VxSS service group and "SecureClus = 1" cluster attribute.
The installvcs program creates the ClusterService service group. The group includes the IP, NIC, and VRTSWebApp resources.
The service group also has the following characteristics:
The service group also includes the notifier resource configuration, which is based on your input to installvcs program prompts about notification.
The installvcs program also creates a resource dependency tree.
If you set up global clusters, the ClusterService service group contains an Application resource, wac (wide-area connector). This resource's attributes contain definitions for controlling the cluster in a global cluster environment.
