I need to come up with a migration path from mixed EV56/EV6 cluster with 
VMS 7.3-2 and 8.4 to VMS auf x86.  It can't be done in one step.

The basic idea is to build a mixed-architecture cluster with HBVS
members on nodes of both types, then gradually move to shadowset members
only on x86 nodes then move to only x86 nodes. 

I can't cluster what I have now with x86 VMS.  I at least have to go to 
VSI VMS.  But I'm pretty sure that I have to go to EV6 for that.  So 
maybe it's not clustering which requires an architecture, but rather 
clustering (in the special case of mixed versions and mixed 
architectures) requiring a version of VMS which in turn requires some 
minimum hardware version.

Even if I could plug my SBB disks into x86, I wouldn't do it, since I 
still need a mixed-architecture cluster to compile and compare before 
switching off the ALPHAs.  (This is similar to how I went from VAX to 
Alpha.)
