Figure 3-1. Cluster Configuration Tool
The Cluster Configuration Tool uses a hierarchical structure to show relationships among
components in the cluster configuration. A triangle icon to the left of a component name
indicates that the component has one or more subordinate components assigned to it. To
expand or collapse the portion of the tree below a component, click the triangle icon.
The Cluster Configuration Tool represents the cluster configuration with the following
components in the left frame:
• Cluster Nodes — Defines 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 — Defines 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. Fence devices must be defined before you can configure fencing
(with the Manage Fencing For This Node button) for each node.
