Installation guide

The nodes and services displayed in the Cluster Status Tool are determined by the cluster
configuration file (/etc/cluster/cluster.conf). You can use the Cluster Status Tool to
enable, disable, restart, or relocate a high-availability service.
4. Command Line Administration Tools
In addition to Conga and the system-config-cluster Cluster Administration GUI, command
line tools are available for administering the cluster infrastructure and the high-availability
service management components. The command line tools are used by the Cluster
Administration GUI and init scripts supplied by Red Hat. Table 1.1, “Command Line Tools”
