Abstract
The method and system provides for continuing issuance of input/output requests on a fabric having a plurality of paths connected to adapters on a computer managing the input/output requests. If a change in a path within the fabric occurs, a registered state change notification is typically issued on the fabric which is detected. The fabric on which the input/output request was issued is searched for a path failure, and if a failure is detected, a path is recovered.
