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. For details, refer to the Oracle Integrated Lights Out Manager (ILOM) 5.0 Documentation Library at https://www.oracle.com/goto/ilom/docs.
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, as described in the following sections:
