Table E.1. Command Line Tool Summary

Command Line ToolUsed WithPurpose
ccs_config_dump — Cluster Configuration Dump ToolCluster Infrastructureccs_config_dump generates XML output of running configuration. The running configuration is, sometimes, different from the stored configuration on file because some subsystems store or set some default information into the configuration. Those values are generally not present on the on-disk version of the configuration but are required at runtime for the cluster to work properly. For more information about this tool, see the ccs_config_dump(8) man page.
ccs_config_validate — Cluster Configuration Validation ToolCluster Infrastructureccs_config_validate validates cluster.conf against the schema, cluster.rng (located in /usr/share/cluster/cluster.rng on each node). For more information about this tool, see the ccs_config_validate(8) man page.
clustat — Cluster Status UtilityHigh-availability Service Management ComponentsThe clustat command displays the status of the cluster. It shows membership information, quorum view, and the state of all configured user services. For more information about this tool, see the clustat(8) man page.
clusvcadm — Cluster User Service Administration UtilityHigh-availability Service Management ComponentsThe clusvcadm command allows you to enable, disable, relocate, and restart high-availability services in a cluster. For more information about this tool, see the clusvcadm(8) man page.
cman_tool — Cluster Management ToolCluster Infrastructurecman_tool is a program that manages the CMAN cluster manager. It provides the capability to join a cluster, leave a cluster, kill a node, or change the expected quorum votes of a node in a cluster. For more information about this tool, see the cman_tool(8) man page.
fence_tool — Fence ToolCluster Infrastructurefence_tool is a program used to join and leave the fence domain. For more information about this tool, see the fence_tool(8) man page.
