Abstract
A method and apparatus for detecting an intermittent path to a storage system comprising accessing path statistics comprising indicia of path state of a path to a storage system, determining whether the path state has changed during a predefined period and, if the path state has changed at least a predefined number of times during the predefined period, identifying the path as intermittent. Once a path is deemed intermittent, the path is aged until either the path is no longer intermittent or the path is deemed dead.
