Maybe you are not even using port name on z/OS. I don't know much about
z/OS, so I cannot help you find it, but even if you are not using port name
in z/OS, you have to be sure that nothing else comes up before the z/OS
guest, connects to the hipersocket and changes port name from nothing into
something.(1) Did you check your z/VSE stack for a port name?
(2) Did you have a chance to reset the hipersocket CHPID (vary off the CHPID
from all LPARs *at the same time*, then vary it on to all)?

I remember that on z800 hardware port names could differ in one character
out of eight (but one only), and microcode check would pass. Eg, port names
HSOA1 and HSOB1 were OK, but not HSOB2. Later on I found out that this is in
fact how it worked. This applied both to hipersockets and OSA's. From z990
onwards, this "slack" was removed and from then on all port names must be
identical or not used at all. So, if you don't really need port names (and
z/VM allows you to not use them from release 4.4 onwards), this exercise of
removing them is well worth your while. And if you do (1) and (2) above, you
will at least be sure that port name is *not* your problem. Then, we'll dig
deeper.
