Overview Of Iop Boot Process - HP NetServer AA 4000 Administrator's Manual

Chapter 2 HP NetServer AA Overview
Figure 2-3 Overview of IOP Boot Process
After the IOPs complete their boot process, the CEs boot: one CE loads the Windows NT
operating system; then the other CE is synchronized so that both CEs perform all CPU and
memory functions in a tightly coupled manner. This ensures that in the event of a CPU or
memory failure, the server operating system provides continuous computing without any loss
of context. After the CE boot process completes, the server is available for use. For an IOP to
service the CE boot request, it must have completed boot, as shown in Figure 2-3 and described
in Appendix B.
The CE boot process is summarized in Figure 2-4. A detailed CE boot process flowchart is in
Appendix B.
