RHEL version 6.1 has been released with new features and improvements. How do I upgrade my HP server running RHEL v6.0 to v6.1 using RHN?

Most of the actions listed in this post are written with the assumption that they will be executed by the root user running the bash or any other modern shell.
# uname -r
