You'll likely want to upgrade the AlphaServer ES40 to V8.4; that isn't 
a big upgrade on OpenVMS Alpha.

In your posting, you seem focused on the proverbial third-wheel of a 
cluster configuration, the quorum disk.  That's not necessary when 
forming a new cluster.  Simplify; reduce your VOTES to 1 and 0, and set 
your EXPECTED_VOTES to 1, and remove the quorum disk specification and 
votes.  Get the two-node configuration working.  (The quorum disk 
polling should prevent you from clobbering things if your network 
connection among the member hosts is offline, but still...)

I'm assuming you haven't had this configuration clustered before.  
(There are issues that will prevent you from reusing either the SCSNODE 
or the SCSYSTEMID within the current cluster, but not with the current 
pairing of those two values; if you've recombined either of those two 
values.)

Assuming that the SCS group ID and the cluster password are correct on 
all hosts, then your network is likely screwed up.  Based on your 
diagnostics, you have no connectivity.  After the SCS group and 
password, check the network switch settings, including the VLAN and 
speed/duplex settings.  Then confirm the switch settings.  Then 
reconfirm the switch settings.  Trust what the network folks tell you, 
but always verify those settings yourself.  (Noticing a pattern here?)
