Error description

  • We have a Windows 2012 Hyper-V server hosting 20 VMs, each of
    which is running Windows 2012. They are assigned virtual HBA
    ports based on a common WWNN generated on the Hyper-V server.
    So, the end result is twenty unique WWPNs that can be zoned,
    mapped, etc.  When I try to add an agentless server, I type in
    the name of one of the hosts. TPC says it has discovered other
    WWPNs related to that host , and it displays all 20 WWPNs of the
    VMs. And, it won't let me remove any of them (all or nothing).
    In other words, this part of the code seems to assume that these
    WWPNs all belong to the same host.  If I try to manually "add
    port" and just type a single WWPN, the same thing happens: TPC
    insists all 20 belong to the same host.  The problem here is
    that all VMs' ports are grouped together with one node WWN on
    the Hyper-V side.
