Figure 1.28. Cluster Configuration Tool
The Cluster Configuration Tool represents cluster configuration components in the configuration file
(/etc/cluster/cluster.conf) with a hierarchical graphical display in the left panel. A triangle
icon to the left of a component name indicates that the component has one or more subordinate
components assigned to it. Clicking the triangle icon expands and collapses the portion of the tree
below a component. The components displayed in the GUI are summarized as follows:
• Cluster Nodes — Displays cluster nodes. Nodes are represented by name as subordinate
elements under Cluster Nodes. Using configuration buttons at the bottom of the right frame (below
Properties), you can add nodes, delete nodes, edit node properties, and configure fencing methods
for each node.
• Fence Devices — Displays fence devices. Fence devices are represented as subordinate
elements under Fence Devices. Using configuration buttons at the bottom of the right frame (below
Properties), you can add fence devices, delete fence devices, and edit fence-device properties.
