You can use the Oracle ILOM command-line interface (CLI) to access the system console.
You can launch multiple console sessions from the Oracle ILOM command-line interface. However, only the first current console session is granted read and write privileges. All other sessions are read-only. Read and write privileges are reassigned when a user with read and write privileges closes their session, and a new serial session is opened.
You are now logged in to the host server operating system through the serial console.
