Abstract
A computer system automatically recovers from a split segment condition in which a contiguous layer 2 network segment, comprising a plurality of contiguous paths each directly coupling one or more members of a team of network resources of the computer system to a core switch of a layer 2 network, is split into two or more noncontiguous segments each comprising a contiguous set of one or more of the plurality of paths. The computer system includes a team of network resources having one or more members that couple it to each one of the plurality of paths. A teaming driver binds the drivers of each member of the team and is coupled to the segment through the members of the team. The teaming driver detects whenever the network segment has been split into two or more noncontiguous segments and then configures the team such that one of the members coupled to a path within each of the noncontiguous segments is designated as a primary resource thereby restoring connectivity of the isolated paths to the computer system.
