Unless you override it with the CHPID xx option, the virtual chpid is selected from the set of chpids NOT present within the LPAR. To find it: 1. ?CP QUERY VIRTUAL xxxx? 2. Find SUBCHANNEL = ssss to get the SCHIB (ssss) 3 ?CP DISPLAY SCHIB ssss? to see the list of associated chpid. Since MVS requires you to know the chpid in advance, we allow you to specify the virtual chpid on the DEFINE NIC command. It is not possible define multiple virtual NICs on the same virtual chpid. > I have 3 persistant LANs defined, VMLAN00, VMLAN01, VMLAN02. > > VMLAN00 is meant as a backbone connection between VM, OS/390, and 2 separate > linux firewall servers.

It looks like the Linux device drivers are buggy in your level of Linux , given the problem goes away when you stop using the LCS device. Try doing the same thing with VM TCP/IP instead of Linux. If you still get errors, then I would contact the Support Center and open a PMR against z/VM.
