3.6. Configuring Cluster Members

Configuring cluster members consists of initially configuring nodes in a newly configured cluster, adding

members, and deleting members. T he following sections provide procedures for initial configuration of

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. T he 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.
