I have a MicroVAX 3500 with a separate R400X enclosure with a total of 4
RF35 disks in it.  The vax names for the disks are

DUA0
DUB1
DUC2
DUD3

After some work I demised that the ra names I needed for 0 and 1 were

DUA0 = ra(0,0,0,0) - {a partition}
DUB1 = ra(0,1,1,0)

However, I cannot figure out how to address disks 2 and 3.  One thing about
the R400X enclosure.  Each bay has 2 disks mounted on one mounting bracket.
 I don't know alot about the vax, but I'm assuming that all 4 disks share
the same adapter.  From the way 1 & 2 are numbered, it appears that each
disk has its own controller.

So, I would surmise that 

DUC2 = ra(0,2,2,0)
DUD3 = ra(0,3,3,0) 

However, this doesn't work.  So I tried 

DUC2 = ra(1,0,0,0) 
DUC2 = ra(1,1,1,0)
DUC2 = ra(1,1,2,0)
DUC2 = ra(1,2,2,0)

every combination causes the system to halt and restart, so I guess all 4
disks do use the same adapter.  Can somebody tell me what I am doing wrong?
 Please copy your response to my email address if possible.
