SVC cluster configuration node failover

A failover system for responding to configuration node failures in a SAN Volume Controller (SVC) cluster, 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 system comprising:

• a hardware processor;
• an activation unit to activate a new configuration node in response to node failures of the original configuration node;
• and
• a storage device event monitoring unit to monitor storage devices managed by the SVC cluster, wherein the storage device event monitoring unit is in a node other than the original configuration node of the SVC cluster, and the storage device is used to store event log information of the original configuration node.

A computer program product for responding to configuration node failures in a SAN Volume Controller (SVC) cluster, the computer program product comprising a non-transitory computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:

• a first executable portion for:
• activating a new configuration node in response to failures of an original configuration node;
• and
• saving with the original configuration node a storage device event log in the plurality of storage devices;
• wherein the storage device event monitoring unit is in a node other than the original configuration node of the SVC cluster.
