    • Provided are a method, system, computer storage device, and storage area network for maintaining a communication path from a host to a storage subsystem in a network. A storage subsystem controls data transfer and access to a storage devices in a network, wherein the storage subsystem is coupled to a switch and the switch is coupled to a host in the network. A topological storage is coupled to the host, the switch and the storage subsystem, for storing a topological coupling relationship between the host and the switch and a topological coupling relationship between the switch and the storage subsystem. In response to determining a failed path between the storage subsystem and the switch coupled to the storage subsystem, the storage subsystem determines a first port on the storage subsystem in the failed path. The storage subsystem determines from the topology storage the topological coupling relationship between the host and the switch and the topological coupling relationship between the switch and the storage subsystem. The storage subsystem redirects, based on the topological coupling relationships, a message sent to the first port of the storage subsystem to an operational second port in the storage subsystem coupled to the switch.
    • 提供了一种用于维护从主机到网络中的存储子系统的通信路径的方法,系统,计算机存储设备和存储区域网络。 存储子系统控制对网络中的存储设备的数据传输和访问,其中存储子系统耦合到交换机,并且交换机耦合到网络中的主机。 拓扑存储器耦合到主机,交换机和存储子系统,用于存储主机和交换机之间的拓扑耦合关系以及交换机和存储子系统之间的拓扑耦合关系。 响应于确定存储子系统和耦合到存储子系统的交换机之间的故障路径,存储子系统确定存储子系统中的故障路径中的第一端口。 存储子系统从拓扑存储确定主机与交换机之间的拓扑耦合关系以及交换机与存储子系统之间的拓扑耦合关系。 存储子系统基于拓扑耦合关系将发送到存储子系统的第一端口的消息重定向到耦合到交换机的存储子系统中的可操作的第二端口。
