z/OS looks at the chpids to find out if it is sharing an OSA and to
confirm parallel connections for Hipersockets. The shared OSA
configuration is important to dynamic VIPA and IP takeover. I can't
remember for sure, but he may check the chpid numbers and compare defined
subnets. A useful thing, really. But it doesn't require specification of
a chpid number since chpid numbers can be extracted from the SCHIB.
We continue to discuss this with z/OS, but Real z/OS Customers should make
their requirements known to z/OS.
If we tell them what we read about in the list server, CS will swish its
tail back and forth a few times, lay its ears back, and look in the
opposite direction, bored to tears. (Claws appear briefly, though remain
unused.) It will go much better coming from the human owners rather than
the bear-penguin cross-breed that really should stay in the back yard or
under the porch and not track mud into the kitchen. ("Shame on you!
