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.

Abstract translation: 存储服务器和特定LUN的存储子系统之间的Lun通信将分配当前路径和备用路径。 Lun通信使用当前路径，除非当前路径被确定为故障。 路径错误可能导致存储服务器确定路径故障。 如果当前的通信路径被确定为故障，则只要备用路径被确定为可靠，则通信将通过备用路径发送。 随着时间的推移，先前确定为有故障的路径可能会恢复并再次用于通信。
