The default cluster port number is 7023, and is automatically assigned when the cluster is created.
The cluster port number does not need to be changed unless a conflict is created by another resource
using the same port number. If there is a port number conflict, change the Port number to any other
value that doesn't cause a conflict.

link.
2 Enter the cluster name or browse and select it, then click the Properties button under the cluster
name.

Click the General tab.
In iManager, the same page used to view or edit the cluster IP address and port properties is
also used for quorum membership and timeout and for cluster e-mail notification.
3.8.4 Resource Priority
The Resource Priority allows you to control the order in which multiple resources start on a given
node when the cluster is brought up or during a failover or failback. For example, if a node fails and
two resources fail over to another node, the resource priority determines which resource loads first.
This is useful for ensuring that the most critical resources load first and are available to users before
less critical resources.
1 In the left column of the main iManager page, locate Clusters , then click the Cluster Options
link.
2 Enter the cluster name or browse and select it, then click the Properties button under the cluster
name.
3
Click the Priorities tab.
4 To change the priority for a resource, select the resource in the list by clicking it, then click the
up-arrow or down-arrow to move the resource up or down in the list. This lets you change the
load order of the resource relative to other cluster resources on the same node.
5 Click the Apply button to save changes made to resource priorities.
3.8.5 Cluster E-Mail Notification
Novell Cluster Services can automatically send out e-mail messages for certain cluster events like

mail addresses for cluster notification.
