130 Verifying the VCS installationVerifying the main.cf file0 sxvcs0011 sxvcs003/etc/llttab/etc/gabtabThe file llttab(1M) contains information that is derived during installation andused by the utility lltconfig(1M). After installation, this file lists the privatenetwork links that correspond to the specific system.For example, the file /etc/llttab contains entries that resemble:set-node sxvcs003set-cluster 8link e1000g2 /dev/e1000g:2 - ether - link e1000g3 /dev/e1000g:3 - ether - The first line identifies the system. The second line identifies the cluster (that is,the cluster ID you entered during installation). The next two lines, beginningwith the link command, identify the two network cards used by the LLTprotocol.Refer to the llttab(4) manual page for details about how the LLT configurationmay be modified. The manual page describes the ordering of the directives in thellttab file.After you install VCS, the file /etc/gabtab contains a gabconfig(1) commandthat configures the GAB driver for use. The file /etc/gabtab contains a line that resembles:/sbin/gabconfig -c -n2where the -c option configures the driver for use and -nN specifies that thecluster is not formed until at least N nodes are ready to form the cluster. Bydefault, N is the number of nodes in the cluster.Note: Symantec recommends not using the -c -x option for /sbin/gabconfig.The Gigabit Ethernet controller does not support the use of -c -x.Verifying the main.cf fileThe installation process creates the VCS configuration file /etc/VRTSvcs/conf/config/main.cf. See “Example main.cf, for clusters without the GCO option” on page 132.See “Example main.cf, for clusters with the GCO option” on page 134.
Verifying the VCS installationVerifying the main.cf file131The main.cf file contains the minimum information that defines the cluster andits 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 locatedin the directory /etc/VRTSvcs/conf/config after installation.Note the following information about the VCS configuration file after installingand configuring VCS:■■■■The cluster definition includes the cluster information that you providedduring the configuration. This 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 programcreates 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 theUseFence = SCSI3 attribute that you added is present.If you configured the cluster in secure mode, the main.cf includes the VxSSservice group and “SecureClus = 1” cluster attribute.The installvcs program creates the ClusterService service group andincludes the following:■■The ClusterService service group includes the IP, NIC, and VRTSWebApp resources.If you configured Cluster Management Console to manage this clusterlocally, the main.cf includes the VRTSWebApp resource that includesAppName = cmc attribute.■ If you configured Cluster Connector so that Cluster ManagementConsole can centrally manage this cluster, the main.cf includes theCMC service group.The CMC service group includes the ClusterConnectorConfig and Processresources.■■■The service group also includes the notifier resource configuration,which is based on your input to installvcs program prompts aboutnotification.The installvcs program also creates a resource dependency tree.If you installed VCS with the Global Cluster Option, the ClusterServiceservice group contains an Application resource, wac (wide-areaconnector), whose attributes contain definitions for controlling thecluster in a Global Cluster environment.Refer to the Veritas Cluster Server User’s Guide for information aboutmanaging VCS global clusters.
