Abstract: Techniques are disclosed relating to storage device failover. In one embodiment, a plurality of storage devices are represented as cluster resources to a cluster resource manager that manages cluster resources on a plurality of cluster nodes. An indication may be received that a failover operation is requested with respect to one of the plurality of storage devices. In response to the indication, the cluster resource manager may initiate the failover operation. In some embodiments, the failover operation includes changing a first access state of the storage device and a second access state of another storage device. In such an embodiment, the storage device and the other storage device may be associated with a logical unit number. In some embodiments, the storage device is located within a first of the plurality of cluster nodes; the other storage device is located within a second of the plurality of cluster nodes.

Abstract translation: 公开了与存储设备故障切换有关的技术。 在一个实施例中，多个存储设备被表示为群集资源，用于管理多个群集节点上的群集资源的群集资源管理器。 可以接收到关于多个存储设备之一请求故障转移操作的指示。 响应于该指示，集群资源管理器可以启动故障切换操作。 在一些实施例中，故障切换操作包括改变存储设备的第一访问状态和另一个存储设备的第二访问状态。 在这样的实施例中，存储设备和其他存储设备可以与逻辑单元号相关联。 在一些实施例中，存储设备位于多个群集节点的第一个内; 另一个存储设备位于多个集群节点的第二个内。
