An administrator is installing an ESX Host to boot from a SAN LUN. The storage array is an active/passive array. After configuring the boot LUN and installing ESX, the system does not boot properly. Which of the following could cause this issue?

A.
The Storage Processor port specified in the BIOS configuration of the HBA is passive

B.
The LUN specified in the BIOS configuration of the HBA is active

C.
The Storage Processor port specified in the BIOS configuration of the HBA is active

D.
The LUN specified in the BIOS configuration of the HBA is passive

Explanation:
VMware ESX Server SAN Configuration Guide, page 60.
When you boot from an active-passive storage array, the storage processor whose world wide name (WWN) is specified in the BIOS configuration of the HBA must be active. If the storage processor is passive, the QLogic adapter cannot support the boot process.
