When accessing the ok prompt, you must specify the PDomain to which you want to connect. Use one of these methods if you need to reach the ok prompt, depending on the current state of the server.
Caution - When you need to shutdown the OS to reach the ok prompt, do so by performing a graceful shutdown of the OS. Any other method might result in the loss of server state data.
