IOPx IOPx is powered on and starts the boot process. IOP passes POST. IOP tests MIC BIOS and calls MIC BIOS. MIC BIOS calls system BIOS. System BIOS starts to load Windows*. Endurance software is loaded. IOP verifies tuple ID. IOPy IOPy is powered on and starts the boot process. IOP passes POST. IOP tests MIC BIOS and calls MIC BIOS. MIC BIOS calls system BIOS. System BIOS starts to load Windows*. Endurance software is loaded. IOP verifies tuple ID. IOP transitions from Offline to Ready. IOPx and IOPy communication is established. IOPs join. IOP transitions from Offline to Ready. CE boot starts. * For an IOP to service the CE boot request, it must have reached the appropriate completed boot. The IOP that services the boot request is one of the following: - If both IOPs are present and are identical, the IOP in the same tuple as the booting CE. - If both IOPs are present and not identical, the IOP with the most current disk services the CE boot request. - If one IOP is available, and if the Endurance server is configured to boot with only that IOP, the only available IOP services the boot request.
