The current IOCP has a hipersocket on CHPID F0 with IODEVICE addresses of
 
0700-070F for the z/OS LPAR.  The z/OS TCPIP definitions for a hipersocke
t 
are required to include the CHPID number of the hipersocket.

Such as:   DEVICE IUTIQDF0 MPCIPA
where the "F0" is the CHPID number of the hipersocket.

If I move that z/OS image from an LPAR to a guest under z/VM I think the 

CHPID would need to be based on the virtual channel address, not on the 

real channel address,and not the real CHPID.  I believe that because if I
 
connect the z/OS to a hipersocket VM Guest LAN there is no real CHPID and
 
no real address.

So, if I use:
   DEDICATE 1700 0700
or NICDEF 1700 TYPE HIPER LAN SYSTEM MYLAN

then the value used on the z/OS TCPIP DEVICE statement would be IUTIQD17.


Is that correct?
