How to Map Node ID to Node Name

During Sun 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; once 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 superuser to list configuration information.

1. Use the scconf(1M) command to list the cluster configuration information.

   % scconf -pv | grep "Node ID"

Example—Mapping the Node ID to the Node Name

The following example shows the node ID assignments

% scconf -pv | grep “Node ID”
(phys-schost-1) Node ID:                    1
(phys-schost-2) Node ID:                    2
(phys-schost-3) Node ID:                    3
