  AlphaServer 4100 and 8200 system disk swaps? 
 The Question is:
 
I have two systems in a cluster, 1 system is running
Openvms 7.1 on a Alpha 4100 box and the other
1 running 6.2 on a Alpha 8200, is it possible to
just switch the system disk without any other
advance configuration so now I have 7.1 running on
my Alpha 8200 and 6.2 running on my Alpha 4100 ?
 
 
 The Answer is:
 
  An AlphaServer 4100 (and any other EV56-based system) requires the
  OpenVMS Alpha V6.2-1H3 release, or the V7.1 or later releases.
 
  Various AlphaServer 8000 series systems (8200, 8400) can have differing
  version requirements.  Specific hardware, such as UltraSCSI, may also
  require particular OpenVMS versions or ECO kits be present, as well.
 
  If the current version is supported for the platform, then yes, the system
  disks can generally be swapped and the system can be rebooted.
 
  Reconfiguration of such things as the DECnet controllers and embedded
  Ethernet addresses and any system-specific configuration steps in the
  site-specific startup command procedures will be required -- controller
  names and device configurations can differ between systems.
 
  You may also need to reset the console environment variables specifying
  the target device and system root, obviously.
