ABSTRACT:
A hypervisor, during device discovery, has code which can examine the south-side management data structure in an adapter's configuration space and determine the type of device which is being configured. The hypervisor may copy the south-side management data structure to a hardware management console (HMC) and the HMC can populate the data structure with south-side data and then pass the structure to the hypervisor to replace the data structure on the adapter. In another embodiment the hypervisor may copy the data structure to the HMC and the HMC can instruct the hypervisor to fill-in the data structure, a virtual function at a time, with south-side management data associations. The administrator can assign south-side data, such as a MAC address for a virtual instance of an Ethernet device, to LPARs sharing the adapter. Thus, a standard way to manage the south-side data of virtual functions is provided.
