Clustering began using a special piece of 'CI' (Computer Interconnect) hardware. When clustering via a LAN, the PEDRIVER (Port Emulator) provides a pseudo-device that looks like a CI but communicates over other network interfaces. The code inside PEDRIVER handles selecting the path to use so you only need PEA0.
The DCL command "MCR LANCP show config/users" will show you which protocols are being used the available ethernet adapters. Cluster traffic is carried on NISCA.

Re: back to back cluster
The sys$examples directory has 2 programs, lavc$start_bus and lavc$stop_bus, that control which controllers run NISCS. See appendices D and E of the "Cluster Systems" manual.
I stop LAVC on my fastest server's gigabit card (keeping it on the 2 100 Mbit ethernets on the motherboard) because otherwise it tends to overwhelm the slower Alphas that have only 100 Mbit interfaces.

Re: back to back cluster
This is during cluster config, but can also be performed using the sysman utility.
The defualt is group number of one and it can get you into a lot of trouble.
You can take a cluster_authorization.dat
from one node, sys$common:[sysexe] and copy it to the other nodes.
