Abstract
A invention is disclosed that provides intelligent failover in a multi-path computer system. Initially, a plurality of data paths to a computer input/output (I/O) device is provided, wherein the plurality of data paths to the computer I/O device are represented as a single logical computer I/O device. Then, during operation, an I/O request to access the computer I/O device is intercepted. A data path from the plurality of data paths to the computer I/O device is then selected, and the computer I/O device is accessed using the selected data path.
