Fibre Channel SR-IOV Requirements and Limitations

    The Fibre Channel SR-IOV feature has the following recommendations and limitations:

  • The SR-IOV card must run the latest version of firmware that supports the SR-IOV feature.

  • The Fibre Channel PCIe card must be connected to a Fibre Channel switch that supports NPIV and that is compatible with the PCIe card.

  • The Logical Domains Manager properly autogenerates unique port-wwn and node-wwn property values by connecting the control domains of all systems to the same SAN fabric and by being part of the same multicast domain.

    If you cannot configure this environment, you must manually provide the node-wwn and port-wwn values when you create the virtual function. This behavior ensures that there are no naming conflicts. See World-Wide Name Allocation for Fibre Channel Virtual Functions.

  • To avoid a panic when switching a Fibre Channel SR-IOV configuration from Fibre Channel 16 (FC16) to Converged Network Adapter (CNA) mode, you must first remove all configurations from the SP.
