I vaguely remember going through this with some SLES12 SP1 testing I did.  The 
kernel does an STSI and then looks for certain bits to be turned on that came 
with (in SUSE's case) the z196/z114.

I just re-ran some Google searches and came up with this:
1. You need Hercules 3.08.2 or higher.  I built 3.12 to use on my workstation.
2. You need to specify "ARCHMODE  z/Arch" in your hercules.cnf file.
