Abstract
An illustrative embodiment of the present invention disclosed herein includes a file server having a file management table to obtain a logical disk ID for accessing files. A logical disk management table is consulted to obtain an I/O path corresponding to the logical disk ID, thus accessing the physical device. When a fault occurs along an I/O path, the appropriate tables are altered accordingly to reflect a new I/O path.
