Abstract: Addressing failure is handled in a nodal system of processor nodes, which comprise at least one processor and at least one interface to a network. Upon detection of a node address failure of a processor node for the network, such as lack of a node address, or presence of a duplicate address, the processor node is disabled from the network, thereby temporarily failing the processor node so that the system remains operational. An alternate node address stored in nonvolatile memory may be selected that avoids the node address failure.
