ABSTRACT:
Described herein are exemplary storage network architectures and methods for diagnosing a path in a storage network. Devices and nodes in the storage network have ports. Port metrics for the ports may be ascertained and used to detect link problems in paths. In an exemplary described implementation, the following actions are effectuated in a storage network: ascertaining one or more port metrics for at least one device at a first time; ascertaining the one or more port metrics for the at least one device at a second time; analyzing the one or more port metrics from the first and second times; and determining if the analysis indicates a link problem in a path of the storage network.
