Abstract:
1. A method for use in determining alternate paths in faulted systems, the method comprising: detecting that a first processor has a problem accessing a target, wherein the first processor has a first path to the target; receiving respective information about communication with the target from each processor of a set of processors, wherein each processor from the set of processors has a respective path to the target, wherein the information includes status of the target; comparing the respective information received from each processor of the set of processors with information of the first processor having the problem accessing the target; based on the comparison, determining an alternate path to the target by identifying that a second processor has better access to the target than the first processor, wherein the second processor has a second path to the target, wherein the set of processors include the first and second processors; and transferring responsibility for I/O communication with the target, from the first processor to the second processor.
