    Abstract: In a data processing system having connected devices, device drivers and device adapters, a device adapter is elected to be the controlling adapter. Requests to a device or devices are transparently routed via the controlling adapter. If a controlling adapter fails, the or one of the remaining device adapters is elected to be the replacement controlling adapter. Requests can continue to be serviced via the replacement controlling adapter, and requests that were in progress at the time of the failure can be reissued for service via the replacement controlling adapter.
