Sun Cluster System Administration Guide for Solaris OS

ProcedureSPARC: How to Display the OpenBoot PROM (OBP) on a Node

Use this procedure if you need to configure or change OpenBoot™ PROM settings.

The phys-schost# prompt reflects a global-cluster prompt. Perform this procedure on a global cluster.

This procedure provides the long forms of the Sun Cluster commands. Most commands also have short forms. Except for the long and short forms of the command names, the commands are identical. For a list of the commands and their short forms, see Appendix B, Sun Cluster Object-Oriented Commands.

  1. Connect to the console on the node to be shut down.

    # telnet tc_name tc_port_number

    Specifies the name of the terminal concentrator.


    Specifies the port number on the terminal concentrator. Port numbers are configuration dependent. Typically, ports 2 and 3 (5002 and 5003) are used for the first cluster installed at a site.

  2. Shut down the cluster node gracefully by using the clnode evacuate command, then the shutdown command. The clnode evacuate command switches over all device groups from the specified node to the next-preferred node. The command also switches all resource groups from the global cluster's specified voting or non-voting node to the next-preferred voting or non-voting node.

    phys-schost# clnode evacuate node
    # shutdown -g0 -y

    Caution – Caution –

    Do not use send brk on a cluster console to shut down a cluster node.

  3. Execute the OBP commands.
