Abstract
A method, system, and apparatus for managing a failed input/output adapter within a data processing system is provided. In one embodiment, an operating system handler receives an indication that one of a plurality of input/output adapters has failed. The operating system handler consults an error log to determine which input/output adapter has failed. Once the bad input/output adapter has been determined, the operating system handler disables the bad input/output adapter and deallocates any processes bound for the bad input/output adapter without powering down the data processing system. A user is then notified of the bad input/output adapter so that the bad input/output adapter can be replaced. The input/output adapter may be replaced without powering down the data processing system. Once the bad input/output adapter has been replace, the new input/output adapter is enabled.
