Changing the name of a cluster node

Edit online

When changing the name of a cluster node, you must stop cluster services, make the change, and then restart cluster services to apply it to the active configuration.

About this task

To change the name of a cluster node:

Procedure

  1. From the command line, enter smit sysmirror
  2. Select Cluster Nodes and Networks > Manage Nodes > Network Interfaces > Change/Show a Node and press Enter. SMIT displays a picklist of cluster nodes.
  3. Make your selection and press Enter. SMIT displays the current node name.
  4. Enter the new name for the node in the New Node Name field. A node name can include alphanumeric characters and underscores, but cannot have a leading numeric. Use no more than 64 characters. When you finish entering data, press Enter. SMIT makes the changes you specified.
  5. After the command completes, return to the PowerHA® SystemMirror® SMIT menus to perform further topology reconfiguration or to synchronize the changes you made.

Results

The change is propagated through both the cluster topology and resource configuration.
