VCS configuration files include the following:
main.cf
The installer creates the VCS configuration file in the /etc/VRTSvcs/conf/config folder by default during the VCS configuration. The main.cf file contains the minimum information that defines the cluster and its nodes.
types.cf
The file types.cf, which is listed in the include statement in the main.cf file, defines the VCS bundled types for VCS resources. The file types.cf is also located in the folder /etc/VRTSvcs/conf/config.
Additional files similar to types.cf may be present if agents have been added, such as OracleTypes.cf.
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 installer 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 is present.
If you configured the cluster in secure mode, the main.cf includes "SecureClus = 1" cluster attribute.
The installer creates the ClusterService service group if you configured the virtual IP, SMTP, SNMP, or global cluster options.
The service group also has the following characteristics:
The group includes the IP and NIC resources.
The service group also includes the notifier resource configuration, which is based on your input to installer prompts about notification.
The installer 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.
Refer to the Cluster Server Administrator's Guide for information about managing VCS global clusters.
Refer to the Cluster Server Administrator's Guide to review the configuration concepts, and descriptions of main.cf and types.cf files for AIX systems.
