Ultrix device names

I have a MicroVAX II that is able to boot into Ultrix 4.3 single user
mode. If I type "mount" it says that /dev/ra0a is mounted on /. I
assume that is my ESDI hard drive since the drives plugged into my
SDC-RQD11-EC ESDI controller are the only ones plugged into my
system. So, my question is, what would the second drive on that
controller be called? Would it be /dev/ra0b or /dev/ra1a? In other
words, what do the "0" and "a" parts of the device name mean? Is "0"
the controller and "a" the device on that controller?
I also have a TD Systems Viking SCSI controller in the system with a
CD-ROM drive attached. What device name would I use for that? I'd
also like to know how to address that drive from the MVII boot prompt
so that I can boot directly off of the CD-ROM.
