SVC CLUSTER CONFIGURATION NODE FAILOVER

摘要

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.

1. A failover method for responding to configuration node failures in a SAN Volume Controller (SVC) cluster, wherein the SVC cluster manages a plurality of storage devices and comprises a plurality of SVCs interconnected via the internet, each SVC acting as a separate node, and at any given time, only one node within the SVC cluster functions as a configuration node to operate external services, the method comprising:
activating a new configuration node in response to failures of an original configuration node.
