ABSTRACT:
A method and system for providing multiple input/output paths for accessing storage devices includes providing two or more logical paths between a virtual I/O client partition and a storage device and establishing a physical path between the virtual I/O client partition and the storage device by assigning the storage device to a first logical path of the two or more logical paths. The method further includes reestablishing the physical path by dynamically assigning the storage device to a second logical path of the two or more logical paths in an event of unavailability of the first logical path.
