What do you mean by "see CSYSTEM and LSYSTEM"....is it definition or actual
status? If actual then one CPC can connect to the other -- so the fiber
link is working, while the other side cannot see CSYSTEM (you presumably
meant production can see only LSYSTEM, as local) -- which narrows the
problem down to what can cause asymetric connectivity. If it really is the
remote system, then its an IOCDS definition problem and not link
performance. A mismatch in the CSYSTEM and LSYSTEM names would cause
failure to connect. I'm suspicious that it is a definition problem, it
should look something like this (sorry for formatting, took it from the z14
redbook):
SYSTEM=(3906,1),LSYSTEM=CETUS, *
RESOURCE PARTITION=((CSS(2),(CETUS2C,1),(CETUS24,2),(CETUS25,3))
CHPID PATH=(CSS(2),04),SHARED, *
PARTITION=(CETUS2C),(=)), *
CPATH=(CSS(0),02),CSYSTEM=DRACO,PCHID=140,PORT=2,TYPE=CL5
CNTLUNIT CUNUMBR=FFF4,PATH=((CSS(2),04)),UNIT=CFP
SYSTEM=(2964,1),LSYSTEM=DRACO, *
RESOURCE PARTITION=((CSS(0),(DRACO01,1)),(DRACO02,2),(DRACO03,3),(*
DRACO04,4)
CHPID PATH=(CSS(0),02),SHARED, *
PARTITION=((DRACO01,DRACO02,DRACO03,DRACO04)), *
CPATH=(CSS(2),04),CSYSTEM=CETUS,PCHID=171,PORT=1,TYPE=CL5
CNTLUNIT CUNUMBR=FFF3,PATH=((CSS(0),02)),UNIT=CFP
