ABSTRACT:
A method and apparatus are provided for dynamically determining a primary adapter in a heterogeneous N-way adapter configuration. Each of the adapters generates information about itself and exchanges the information with all other adapters. First a decision-making adapter is identified. Then the decision-making adapter compares the adapter-generated information of all the adapters and makes a decision determining the primary adapter. The decision-making adapter communicates the decision to all other adapters. The determined primary adapter assumes a role as the primary adapter and the other adapters assume a role as a secondary adapter.
