What is the error you getting while booting up?

Have you tried to contact to support?

Well, without telling us what version Red Hat you're using, exactly what you did, what the 'two lines' say, what the one line you entered was, or provide ANY relevant details at all, there's little we can help you WITH.

Your first/best course of action is to call Red Hat support, since you're paying for it with your RHEL subscription. Aside from that, just changing a runlevel shouldn't affect the server, unless you also made other changes...did you? Have you tried a second reboot?

Have you tried to rescue the server with CD ..

Running rescue mode may not even be needed, since the OP hasn't actually given us enough information/details to provide a reasonable guess. Since they haven't said what the server is doing, why would you suggest booting into rescue mode? What do you think that will do to help the OP?
