If set to a value greater than 0, multipathd will make sure that when path failures has exceeded the san_path_err_threshold within san_path_err_forget_rate then the path will be placed in failed state for san_path_err_recovery_time duration. Once san_path_err_recovery_time has timeout we will reinstante the failed path. san_path_err_recovery_time value should be in secs.
