8.3 Entering the OpenBoot PROM on a Sun Cluster Server

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

8.3.1 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.
