Firstly, the Dolby Digital Cinema (DSS100/200/220 and cat862/745) installation and user manager doesn't give you any useful information for troubleshooting this problem. However, if you still want it, email cinemasupport [at] dolby.com, and I'm sure that they'd be happy to send it to you.
If by DCP drives you mean the RAID drives, then I guess that your problem lies either in the RAID controller card, or in the backplane of the RAID drive cage. That is what the SATA power connectors for the individual drives are hooked to. The data connectors go through that backplane to the 3Ware RAID controller card that is in one of the PCI-E slots on the motherboard.
If you can see the 3Ware RAID controller boot during the startup sequence, but it can't see any drives, then that does look like a power supply problem. If you don't see the 3Ware card booting, then it's likely that card. Either fault would result in Show Manager not being able to see any RAID.

The Doremi 4U chassis servers (DC4 & SV4) have a known problem with the PSUs. Turned off but powered, the power supplies still make DC power for the network ports, to turn on, and other things - +5V standby. No fans run in this off but powered state. The supplies get hot. Sometimes a sensor says they are too hot to start making the high current voltages needed to turn the server on. The monitoring system that beeps when a supply fails only senses the standby power, so it doesn't beep for this. If you press the start button and see a flicker in the LEDs and maybe hear fans start then stop, followed by a normal startup in a second or two... one of the supplies is either in this hot state or has really failed, and can't make the high current voltages. Turn off one supply at a time with the unit on, the beeper will sound and the server should stay on. If it shuts off instantly the supply still on is dead (except for standby +5V).If it does stay running turn the switch back on and the other one off when the beeping stops. If both supplies are in the hot state - this shows as no starting after sitting a while powered up but not running - , switch them off for a few minutes and they will work again. If one is, and the other one starts the system, the fans will run and cool down both quickly. There is no official fix. Putting a small fan where it blows into the power supplies gives enough cooling to eliminate the problem.
