So I'm *almost* sure that you can run one without
the OCP. Mind you, it
might have been an RA71 or RA72 rather than an RA70.
Right now I cannot put my finger on a suitable manual ...
There are, I'm sure, some jumpers or switches that set the unit number.
There is a DIP switch on the back next to the Fault and Ready LEDs
that is labeled Unit Number Select. Next to the DIP switch is a
pushbutton labeled Unit Number Accept. I have all of the DIP switches
off, I suspect for Unit Number 0. I tried pushing the Unit Number
Select push button both after the drive was powered up and while it
was being powered up. It does not spinup.

I just now connected an RA70 to an M7164/M7165 KDA50 in my 4000-700A.
On powering up the RA70 by itself it does nothing. On powering up the
4000-700A the RA70 still does nothing. On doing a >>>SHOW DEV the
RA70 appears in the device list as DUA0 but still does nothing. It is
not until I do a >>>BOOT DUA0 that that RA70 spins up. This is with
just a bare RA70 with no OCP attached.
It appears that the RA70 needs to be commanded to spinup by the
controller before it will do so and it will not spinup on its own.
