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

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

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 A, Sun Cluster Object-Oriented Commands.

1. Connect to the console on the node to be shutdown.

   # telnet tc_name tc_port_number

   tc_name

   Specifies the name of the terminal concentrator.

   tc_port_number

   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 global or non-global zones on the specified node to the next-preferred global or non-global zones on other nodes.

   # clnode evacuate node # shutdown -g0 -y

   Caution –

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

3. Execute the OBP commands.
