Terminology is ambiguous here, because it gets misused.  A "HiperSocket" 
is a CHPID TYPE=IQD (or a z/VM Guest LAN defined with TYPE HIPERS).  You 
can define up to 16 HiperSocket chpids.  Each chpid can have up to 64 
control units, with 256 devices (subchannels) per control unit, not to 
exceed 12K devices in total (for all HiperSocket chpids taken together.

Because a host requires 3 devices (subchannels) to connect to a 
HiperSocket, you can have at most 4096 different concurrent users of all 
of your HiperSocket chpids, whether they are guests on z/VM or individual 
LPARs.

That's because you only put 16 IODEVICE entries in your IOCDS on the 
chpid.  Define more.
