Applying operating system patches is often time consuming and disruptive. In fact, most patching techniques require
systems and disks to be taken offline for the patching process. The Solaris Live Upgrade software enables administrators
to stage patches without impacting running systems, and minimize the actual downtime associated with patching to the time
needed to reboot the system. This Sun BluePrints article discusses how the Solaris Live Upgrade software can be used to
patch mirrored systems and rollback to the pre-patched environment should the need arise. While this article focuses on Sun
systems incorporating SPARC processors that run the Solaris 8, 9, and 10 Operating System (OS), the procedures can be used on
x86 and x64 systems as well. However, device naming conventions may be different on these systems. It is important to note that
the procedures outlined in this document assume knowledge of the Solaris Volume Manager software and experience with patching
the Solaris Operating System on Sun servers.
