Add a System_Identifier (not System_Identifier_Default) that is
pre-defined with the CPU serial number of the DR site.  Or reverse it and
make ZVMCS3 the default and add a statement to cover your home system.

Having done as described above, you can prefix the VMLAN statement with
the system id.  E.g.
   ZVMCS3: VMLAN xxxxx
   ZVMCS1: VMLAN yyyyy

Use "nodeid TCPIP" instead of PROFILE.  The node name comes from SYSTEM
NETID S.  That, too, is selected by CPU ID.  IF there is no matching entry
in SYSTEM NETID, the default node name will be the System_Identifer.

All of the changes above will be in your *production* system and will be
replicated.  All is geared off of the SYSTEM_IDENTIFIER.
