Note
Stopping cluster software on a node causes its HA services to fail over to another node. As an
alternative to that, consider relocating or migrating HA services to another node before
stopping cluster software. For information about managing HA services, refer to Section 8.3,
“ Managing High-Availability Services” .
8.2. Delet ing or Adding a Node
This section describes how to delete a node from a cluster and add a node to a cluster. You can
delete a node from a cluster according to Section 8.2.1, “ Deleting a Node from a Cluster”; you can
add a node to a cluster according to Section 8.2.2, “ Adding a Node to a Cluster”.
8.2.1. Delet ing a Node from a Clust er

deleted and updating the cluster configuration to reflect the change.
Important
If deleting a node from the cluster causes a transition from greater than two nodes to two
nodes, you must restart the cluster software at each node after updating the cluster
configuration file.
To delete a node from a cluster, perform the following steps:
