Embodiment Construction

[0013] Referring now to the figures, and in particular to FIG. 1 , there are depicted block diagrams of data processing systems in which illustrative embodiments may be implemented. Data processing system 100 may be a symmetric multiprocessor (SMP) system including multiple processors 101 , 102 , 103 , and 104 coupled to system bus 106 . For example, data processing system 100 may be an IBM eServer, a product of International Business Machines Corporation of Armonk, NY, implemented as a server in a network. Alternatively, a single processor system can be used. Also connected to system bus 106 is memory controller / cache 108, which provides an interface to a plurality of local memories 160-163. I / O bus bridge 110 is connected to system bus 106 and provides an interface to I / O bus 112 . Memory controller / cache 108 and I / O bus bridge 110 may be integrated as described.

[0014] Data processing system 100 is a logical partition (LPAR) data processing system. Thus, data processi...

Abstract

A method, apparatus, and computer instructions are provided for propagating a physical device's link status to one or more virtual devices associated with the physical device. Link status information about the physical device indicating a failure in the physical device is identified using partition management firmware. The link status information about the physical device is propagated by partition management firmware to one or more virtual devices associated with the physical device. The logical partition using the virtual device use the virtual device link status to determine if a physical link to an outside network is down, and take appropriate remedial actions as may be necessary.

Description

technical field [0001] The present invention relates generally to an improved data processing system and in particular to an improved method and apparatus for processing data. More particularly, the present invention provides a method and apparatus for propagating link state information from a physical Ethernet adapter to a virtual Ethernet adapter in a data processing system with logical partitions (LPARs). Background technique [0002] In data processing systems that may be divided into logical partitions (LPARs), virtual Ethernet adapters (VEAs) are used to provide network connectivity between the logical partitions. As far as the logical partition's operating system is concerned, a virtual Ethernet adapter behaves like any regular physical Ethernet adapter (PEA). Partition management firmware connects logical partitions and provides network connectivity between them. A hypervisor is an example of such partition management firmware. When network activity is limited to ...
