Abstract
A method is used in determining alternate paths in faulted systems. It is detected that a first processor has a problem accessing a target. The first processor has a first path to the target. An alternate path to the target is determined by identifying that a second processor has better access to the target than the first processor. The second processor has a second path to the target. Responsibility for I/O communication with the target is transferred from the first processor to the second processor. Responsibility for I/O communication with the target is transferred back to the first processor upon resolution of the problem.
