Abstract: Lun communications between a storage server and a storage subsystem for a particular lun are assigned both a current path and an alternate path. Lun communications use the current path unless the current path is determined to be faulty. Path errors may result in the storage server determining a path to be faulty. If the current path for a lun communication is determined to be faulty, then the lun communications will be sent through the alternate path so long as the alternate path is determined to be reliable. Over time, a path previously determined to be faulty may recover and be used again for lun communications.
