  • 1.  Networking Issues for Second NIC

    Posted Wed February 15, 2017 03:20 PM

    We are trying to get a 2nd z/OS OSA definition operational on a 2nd (not the primary) NIC defined to the zD&T server.

    We have the base z/OS OSA operational (F0 below) but can't get the configuration setup for the second (F1) NIC.

    We've reviewed the different "scenarios" but are still having problems.  We opened a PRM, . . . "However, we do not provide
    support for configuring the ADCD zOS nor on the host Linux" was the reply.

    HELP. What can/should we provide for assistance?

    We have added a new network interface to our z/RDT Red Hat Linux       
    environment (7.2 Maipo, Kernel = 3.10.0-327.36.1.el7.x86_64), with a   
    new QDIO OSA device in z/OS V2.1.  The VTAM TRL for the new OSA comes  
    active without issue, but we cannot move packets through the device.   
                                                                           
    The new OSA is host 192.168.32.211 on network 192.168.32.208/28, and is
    modeled after a similar (native) z/OS interface on this network at     
    192.168.32.209.

    Did you look at the zPDT Guide and Reference redbook (SG24-8205), chapter 7.2? There are some prepared scenarios in zD&T that might help you in network configurations.
