[Info-vax] Alpha doesn't want to work in a cluster

Hello all,

I'd like to create a cluster from ES40 (VMS 7.3-2) and Integrity Rx2800 (VMS 8.4). Yes, I know this combination is unsupported, but it's not a production cluster anyway. Quorum disk is the fibre disk. Integrity works as expected, but Alpha does not. So finally to make life simpler I shut Integrity down, deleted QUORUM.DAT (created by Intergity) from the quorum disk and continued with the Alpha alone in the cluster with the quorum disk. But it's still no success. Alpha is booting, reporting
CNXMAN - using remote access method to the quorum disk
....
CNXMAN - proposing formation of VMScluster
CNXMAN - now is VMScluster member, node Alpha
CNXMAN - completing VMScluster state transition
  and nothing more happenning.
As far as there is no message "CNXMAN - using local access method to the quorum disk", as it happens on Integrity, so I think it's a some problem acessing quorum disk, but I can't understand why. This disk is definitely accessible from the Alpha when it booted in non-cluster environment. So  I trust it's not a problem with disk presentation in the EVA array or/and zoning in the SAN.
So what else?
