Fence Device.
2. Click Configure a Fence Device. Clicking Configure a Fence Device causes the display of a list
of fence devices under Configure a Fence Device.
3. Click a fence device in the list. Clicking a fence device in the list causes the display of a Fence
Device Form page for the fence device selected from the list.
4. Either modify or delete the fence device as follows:

3.6. Configuring Cluster Members

Configuring cluster members consists of initially configuring nodes in a newly configured cluster,
adding members, and deleting members. The following sections provide procedures for initial
configuration of nodes, adding nodes, and deleting nodes:
Section 3.6.1, "Initially Configuring Members"
•
Section 3.6.2, "Adding a Member to a Running Cluster"
•
Section 3.6.3, "Deleting a Member from a Cluster"

3.6.1. Initially Configuring Members

Creating a cluster consists of selecting a set of nodes (or members) to be part of the cluster. Once you
have completed the initial step of creating a cluster and creating fence devices, you need to configure
cluster nodes. To initially configure cluster nodes after creating a new cluster, follow the steps in this
section. The starting point of the procedure is at the cluster-specific page that you navigate to from
Choose a cluster to administer displayed on the cluster tab.
1. At the detailed menu for the cluster (below the clusters menu), click Nodes. Clicking Nodes
causes the display of an Add a Node element and a Configure element with a list of the nodes
already configured in the cluster.
2. Click a link for a node at either the list in the center of the page or in the list in the detailed menu
under the clusters menu. Clicking a link for a node causes a page to be displayed for that link
showing how that node is configured.
