Endurance Boot Process

When the IOPs and CEs in an Endurance server are powered on, they automatically start a boot
process that results in loading both the Windows operating system and the Endurance software.
When powered on, the IOPs pass power-on self test (POST) and load the Windows operating
system and the Endurance software. The IOP boot process must complete for the CEs to begin
their boot process. (If the CEs are powered up at the same time as the IOPs, the CEs complete
their POST, and then wait for the IOPs to complete their boot process.)
The CEs do not begin booting until the IOPs are available because all I/O devices (including the
CE boot disk) physically reside on the IOPs. By default, both IOPs must be present for the
Endurance server to continue the boot process. This ensures that both CEs use the correct copy
of the operating system and do not run independently. The IOP boot process is summarized in
Figure 2-3. A detailed IOP boot process flowchart is in
