ABSTRACT:
An information processing system comprises a storage and a plurality of information processing apparatuses requesting data input/output from the storage. The information processing apparatus comprises an error detection section, a changeover evaluation section, and a changeover section. The error detection section detects an error occurred on a path according to a result of a data input/output request. The changeover evaluation section detects occurrence of error on a specified number of paths to determine whether or not to change an information processing apparatus connected to the storage even before occurrence of errors on all paths. The changeover section uses a determination result from the changeover evaluation section to change the information processing apparatus which requests data input/output from the logical unit.
