Chapter 2 HP NetServer AA Overview CEx Powered on and completes POST CEy Powered on and completes POST CE issues boot request. IOP services boot request. IOP servicing boot redirects its keyboard to the CE. CE issues boot request. CE loads Windows NT and Endurance software. CE has active control of all redirected devices. If IOPs are both present and their disks are not current, a mirror copy starts. CEs synchronize and start executing in lock step. Figure 2-4 Overview of CE Boot Process By default, when the server completes the entire boot process, the keyboard and pointer (mouse) on each IOP control the CE operating system. Use Ctrl-Shift-F12 or a key sequence you define, or use the CE tray icon to toggle input control between the CEs and local IOP. Warning: Once the CEs have synchronized, do not physically attach or remove keyboards or any devices from a CE. Doing so could cause loss of synchronization in some CE models. 19
