Verify the CMOD Configuration

Before or after you change the socket mode configuration of the system, verify that the current socket mode is configured correctly.

  1. Log in to the System A or System B SP Oracle ILOM CLI.

    Log in as a user with root or administrator privileges. For example, open an SSH session:

    ssh root@ ipaddress

    Where ipaddress is the IP address of the server SP.

    For more information, see Using Oracle Integrated Lights Out Manager (ILOM) in Oracle Server X8-8 Installation Guide.

    The Oracle ILOM CLI prompt appears: ->

  2. Display the current system configuration using the hwdiag command.

    The hwdiag commands are accessed from the Oracle ILOM Diag shell. For information about the Diag shell and how to use the hwdiag commands, see Troubleshooting Using Diagnostic Tools.

    Enter the Oracle ILOM Diag shell. From the Oracle ILOM command-line interface (CLI), type:

    -> start /SP/diag/shell
 Are you sure you want to start /SP/diag/shell (y/n) ? y
  3. Confirm that CMODs 0-3 match CMODs 4-7 to ensure all eight CMODs have identical processors installed.
    1. At the Diag shell prompt, type:
