Configuring Serial Port Sharing

By default, the service processor (SP) controls the serial management (SER MGT) port and uses it to redirect the host serial console output. Using Oracle ILOM, you can assign the host console (COM1) as owner of the SER MGT port output, which allows the host console to output information directly to the SER MGT port. Serial port sharing is useful for Windows kernel debugging, because you can view non-ASCII character traffic output from the host console.

Set up the network on the SP before attempting to change the serial port owner to the host server. If the network is not set up first, and you switch the serial port owner to the host server, you cannot connect using the CLI or web interface to change the serial port owner back to the SP. To return the serial port owner setting to the SP, restore access to the serial port on the server.

If you accidentally lose access to Oracle ILOM, contact Oracle Service and follow the process to return the serial port ownership back to the SP.

You can assign serial port output using either the Oracle ILOM CLI interface or web interface:

Oracle ILOM CLI interface

  1. Open an SSH session, and at the command line, log in to the SP Oracle ILOM CLI.

    Log in as a user with root or administrator privileges. For example: ssh root@ ipaddress Where ipaddress is the IP address of the server SP.

    The Oracle ILOM CLI prompt (->) appears.

  2. To set the serial port owner, type: -> set /SP/serial/portsharing owner=host

    Note:

    The serial port sharing value, by default, is owner=SP.
  3. Connect a serial host to the server.

Oracle ILOM web interface

  1. Log in to the SP Oracle ILOM web interface.

    Open a web browser and direct it using the IP address of the server SP. Log in as root or a user with administrator privileges.

  2. On the Summary Information page, select ILOM Administration → Connectivity from the navigation menu on the left side of the screen.
  3. Select the Serial Port tab.

    Note:

    The serial port sharing setting, by default, is Service Processor.
  4. On the Serial Port Settings page, select Host Server as the serial port owner.
  5. Click Save for the changes to take effect.
  6. Connect a serial host to the server.
