Configuring Cluster Members; Initially Configuring Members - Red Hat Cluster for Enterprise Linux 5 Configuration

1. At the detailed menu for the cluster (below the clusters menu), click Shared Fence
Devices. Clicking Shared Fence Devices causes the display of the fence devices for a
cluster and causes the display of menu items for fence device configuration: Add a Fence
Device and Configure a Fence Device.
2. Click Configure a Fence Device. Clicking Configure a Fence Device causes the display

You can create shared fence devices on the node configuration page, also.
However, you can only modify or delete a shared fence device via Shared
Fence Devices at the detailed menu for the cluster (below the clusters
menu).

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 6.1, "Initially Configuring Members"
• Section 6.2, "Adding a Member to a Running Cluster"
• Section 6.3, "Deleting a Member from a Cluster"

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.
