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.
