SVC CLUSTER CONFIGURATION NODE FAILOVER SYSTEM AND METHOD |
摘要 |
Methods, systems, and computer programs are provided for failover responses to configuration node failures in SVC clusters. An SVC cluster manages a plurality of storage devices and includes a plurality of SVCs interconnected via a network, each SVC acting as a separate node. A new configuration node is activated in response to configuration node failures. The new configuration node retrieves client subscription information about events occurring in storage devices managed by the SVC cluster from the storage devices. In response to events occurring in the storage device managed by the SVC cluster, the new configuration node obtains storage device event information from a storage device event monitoring unit. The new configuration node sends storage device events to clients who have subscribed to this information according to subscription information obtained. The storage device is not installed in the original configuration node. This method allows complete transparency of the configuration node failover process to clients. |
