Dynamic SR-IOV Configuration Requirements

To dynamically create or destroy a virtual function, ensure that the following conditions are met:

• I/O virtualization has been enabled for a PCIe bus before you begin to configure virtual functions.

• The OS that runs on the root domain and on I/O domains must be at least the Oracle Solaris 11.1 SRU 10 OS.

• The physical function device is not configured in the OS or is in a multipathing configuration. For example, you can unplumb an Ethernet SR-IOV device or have it in an IPMP or an aggregation to successfully create or destroy a virtual function.

  An operation to create or destroy a virtual function requires that the physical function device driver toggle between the offline and online states. A multipathing configuration permits the device driver to toggle between these states.

• The virtual function is either not in use or in a multipathing configuration before you remove a virtual function from an I/O domain. For example, you can either unplumb an Ethernet SR-IOV virtual function or not use it in an IPMP configuration.

  Note:

  You cannot use aggregation for Ethernet SR-IOV virtual functions because the current multipathing implementation does not support virtual functions.
