So now I'm trying to define a shared CTC environment so that I can connect a
real CTC to a 2nd level vm.
It was working when I dedicated the CHPID to each partition. Now that I am
sharing the CHPIDs between LPARS the the 2400 range will not come online to
either LPAR. Messages and relevant pieces of IOCDS is below.
