In any case, I don't think that is the biggest problem, the drives themselves are not dependant on the PERC controller to 'spin up'. They should do this even if they only have power connected. I think you have drive / power problems, not a PERC controller problem.
That's not strictly true depending on the hardware. I'm not entirely certain how this is accomplished but, in some systems, the spin-up is actually controlled by the raid controller itself. Whether this is accomplished through some funky stuff in the enclosure/case or if there is some sort of signalling on the data cable, I know it is done - usually to limit power draw during startup.
Of course, the drives will spin up automatically in the absence of any stimulus to the contrary - they wouldn't be terribly useful if they didn't.
All that said, I'd guess you have a disk that is failing in a way that the controller is not able to handle.
