How to Map Node ID to Node Name

During Oracle Solaris Cluster installation, each node is automatically assigned a unique node ID number. The node ID number is assigned to a node in the order in which it joins the cluster for the first time. After the node ID number is assigned, the number cannot be changed. The node ID number is often used in error messages to identify which cluster node the message concerns. Use this procedure to determine the mapping between node IDs and node names.

You do not need to be the root role to list configuration information for a global cluster or a zone cluster. One step in this procedure is performed from a node of the global cluster. The other step is performed from a zone-cluster node.

  1. Use the clnode command to list the cluster configuration information for the global cluster.
    phys-schost# clnode show | grep Node

    For more information, see the clnode (1CL) man page.

  2. You can also list the Node IDs for a zone cluster.

    The zone-cluster node has the same Node ID as the global cluster-node where it is running.

    phys-schost# zlogin sczone clnode -v | grep Node
Example 9-2  Mapping the Node ID to the Node Name

The following example shows the node ID assignments for a global cluster.

phys-schost# clnode show | grep Node
=== Cluster Nodes ===
Node Name:				phys-schost1
Node ID:				1
Node Name: 				phys-schost2
Node ID:				2
Node Name:				phys-schost3
Node ID:				3
