注意

交​​​​​​​互​​​​​​​式​​​​​​​地​​​​​​​创​​​​​​​建​​​​​​​ zFCP 设​​​​​​​备​​​​​​​只​​​​​​​能​​​​​​​在​​​​​​​图​​​​​​​形​​​​​​​模​​​​​​​式​​​​​​​的​​​​​​​安​​​​​​​装​​​​​​​程​​​​​​​序​​​​​​​里​​​​​​​进​​​​​​​行​​​​​​​。​​​​​​​在​​​​​​​文​​​​​​​本​​​​​​​模​​​​​​​式​​​​​​​的​​​​​​​安​​​​​​​装​​​​​​​里​​​​​​​,不​​​​​​​可​​​​​​​能​​​​​​​交​​​​​​​互​​​​​​​式​​​​​​​地​​​​​​​配​​​​​​​置​​​​​​​ zFCP 设​​​​​​​备​​​​​​​。​​​​​​​
输​​​​​​​入​​​​​​​的​​​​​​​每​​​​​​​个​​​​​​​值​​​​​​​都​​​​​​​应​​​​​​​该​​​​​​​被​​​​​​​校​​​​​​​验​​​​​​​来​​​​​​​确​​​​​​​认​​​​​​​其​​​​​​​正​​​​​​​确​​​​​​​性​​​​​​​。​​​​​​​任​​​​​​​何​​​​​​​错​​​​​​​误​​​​​​​都​​​​​​​会​​​​​​​导​​​​​​​致​​​​​​​系​​​​​​​统​​​​​​​无​​​​​​​法​​​​​​​正​​​​​​​确​​​​​​​操​​​​​​​作​​​​​​​。​​​​​​​
关​​​​​​​于​​​​​​​这​​​​​​​些​​​​​​​值​​​​​​​的​​​​​​​详​​​​​​​情​​​​​​​,请​​​​​​​参​​​​​​​考​​​​​​​系​​​​​​​统​​​​​​​附​​​​​​​带​​​​​​​的​​​​​​​硬​​​​​​​件​​​​​​​文​​​​​​​档​​​​​​​,并​​​​​​​向​​​​​​​为​​​​​​​该​​​​​​​系​​​​​​​统​​​​​​​设​​​​​​​置​​​​​​​联​​​​​​​网​​​​​​​的​​​​​​​系​​​​​​​统​​​​​​​管​​​​​​​理​​​​​​​员​​​​​​​咨​​​​​​​询​​​​​​​。​​​​​​​

注意

The installer requires that at least one ECKD DASD be defined. In the situation where a SCSI-only installation is desired a DASD= parameter should be entered into the CMS conf file with a non-existent device number. This will satisfy Anaconda's requirement for a defined ECKD DASD, while resulting in a SCSI-only environment.
