I'm just wondering whether there's a compelling reason to take a system down to maintenance (SMS) mode in order to install server firmware. It has been a while, but I seem to remember using the AIX diag utility to accomplish that task.<br />

Installing Server Firmware on an AIX System

Unix is a multitasking, multi-user computer operating system originally developed in 1969 at Bell Labs. Today, it is a modern OS with many commercial flavors and licensees, including FreeBSD, Hewlett-Packard’s UX, IBM AIX and Apple Mac OS-X. Apart from its command-line interface, most UNIX variations support the standardized X Window System for GUIs, with the exception of the Mac OS, which uses a proprietary system.
