Hi, i didn't understand if E8xx and E9xx are on the same chpid... i think they are. it seems you were on the right path but you missed something... on z/OS you have created 3 devices that are all on the same subnet. defining 3 routes to each Device will not help. how will z/OS know when to use which path? in your case it always uses the first. that is why E8 keeps working. because you added more IP addresses to z/OS i guess that you don't mind that E9 guests will reach z/OS using a different IP address. That said, you can define each device group (E8, E9 etc) in a different VLAN. Check out the DEVICE/LINK/INTERFACE statements to select the VLAN to use. that will allow you to use more than one subnet on that chpid. if i got it wrong and you want all guests and z/OS to be on the same subnet than you must add more devices to E8xx as Alan said...
