Sun Cluster 2.2 System Administration Guide

Entering the OpenBoot PROM on a Sun Cluster Server

This section contains information for entering the OpenBoot PROM from the Terminal Concentrator.

How to Enter the OpenBoot PROM
  1. Connect to the port.


    # telnet terminal-concentrator-name 5002
    Trying 192.9.200.1 ...
    Connected to 129.9.200.1 .
    Escape character is '^]'.

  2. Stop the cluster software, if necessary, by using the scadmin stopnode command, and then halt the system.

    Halt the system gracefully by using the halt(1M) command.


    # halt
    

    If halting the system with the halt(1M) command is not possible, then enter the telnet(1) command mode. The default telnet(1) escape character is Control-].

  3. Send a break to the node.


    telnet> send brk
    

  4. Execute the OpenBoot PROM commands.
