Abstract
A minimally degraded configuration is determined when failing connections occur. Associative deconfigurations are determined from deconfiguring hardware items in a server system, associative groups are derived, and failed connections are determined. Failed connections are determined between two hardware items that are in the same associative group, and the two hardware items at both endpoints of the failed connection are deconfigured. Each associative group state is set to unknown, and the failed connections are counted where a single endpoint of the failed connection is within the associative group. The associative group state is set to deconfigured, if a member of the associative group was deconfigured. Counts of the associative groups that remain in the unknown state are analyzed, and the associative group with the smallest failed connection count is selected and set to a configured state. The other associative group at the other end is set to a deconfigured stated, and the hardware item in the other associative group is deconfigured.
