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 Man-
age Fencing For This Node button) for each node.
• Managed Resources — Displays failover domains, resources, and services.
• Failover Domains — For configuring one or more subsets of cluster nodes used to run a
high-availability service in the event of a node failure. Failover domains are represented
as subordinate elements under Failover Domains. Using configuration buttons at the
bottom of the right frame (below Properties), you can create failover domains (when
Failover Domains is selected) or edit failover domain properties (when a failover domain
is selected).
• Resources — For configuring shared resources to be used by high-availability services.
Shared resources consist of file systems, IP addresses, NFS mounts and exports, and
user-created scripts that are available to any high-availability service in the cluster. Re-
sources are represented as subordinate elements under Resources. Using configuration
buttons at the bottom of the right frame (below Properties), you can create resources
(when Resources is selected) or edit resource properties (when a resource is selected).
Note
The Cluster Configuration Tool provides the capability to configure private
resources, also. A private resource is a resource that is configured for use
with only one service. You can configure a private resource within a Service
component in the GUI.
• Services — For creating and configuring high-availability services. A service is con-
figured by assigning resources (shared or private), assigning a failover domain, and de-
fining a recovery policy for the service. Services are represented as subordinate ele-
ments under Services. Using configuration buttons at the bottom of the right frame
(below Properties), you can create services (when Services is selected) or edit service
properties (when a service is selected).
