Abstract

A system is provided that includes a plurality of storage network devices and a storage manager communicatively coupled to the plurality of storage network devices. The storage manager includes a discovery engine configured to collect configuration information from the plurality of storage network devices. The system also includes an object model that represents the storage network system and is updated based on the configuration information collected by the discovery engine. The system also includes a mapping file that guides the discovery engine during an update of the object model. The discovery engine is triggered to perform a limited update of the object model upon the completion of a storage management operation.

Claims

5-1. The storage network system of claim 1, wherein the discovery engine is configured to collect configuration information from the plurality of storage network devices by sending SMI-S based information requests to the one or more of the storage network devices.

11. A method for updating configuration information of a storage network system, comprising:

receiving a result of a storage management operation performed on the storage network system, wherein the result of the storage management operation identifies a storage object immediately affected by the storage management operation;

identifying an initial node corresponding to the storage object in a mapping file and replicating the storage object based on instructions contained in the initial node;

traversing the mapping file starting from the initial node to identify additional storage objects that have been affected by the storage management operation and replicating the additional storage objects.

12. The method of claim 11, wherein traversing the mapping file comprises identifying a parent node of the initial node, the method comprising replicating a parent storage object corresponding to the parent node based on instructions contained in the parent node.

13. The method of claim 11, wherein traversing the mapping file comprises identifying a child node of the initial node, the method comprising replicating a child storage object corresponding to the child node based on instructions contained in the child node.

14. The method of claim 11, wherein traversing the mapping file comprises identifying a storage object corresponding to a node that is outside the subtree of the initial node.

15. The method of claim 11, wherein storage objects that are not affected by the storage management operation are not updated.

16. The method of claim 11, wherein the storage management operation is a volume provisioning operation and the initial node corresponds with a volume created by the volume provisioning operation.

17. A non-transitory, computer-readable medium, comprising code configured to direct a processor to:

receive a result of a storage management operation performed on a storage network system, wherein the result of the storage management operation identifies a storage object immediately affected by the storage management operation;

identify an initial node corresponding to the storage object in a mapping file and replicate the storage object based on instructions contained in the initial node; and

traverse the mapping file starting from the initial node to identify additional storage objects that have been affected by the storage management operation and replicate the additional storage objects.

18. The method of claim 17, wherein traversing the mapping file comprises:

traversing from the initial node to parent nodes of the initial node and child nodes of the initial node; and

at each parent node and child node, collecting configuration information from storage network devices corresponding to the node in accordance instructions contained in the node.

19. The method of claim 17, wherein traversing the mapping file comprises identifying a node that is outside the subtree of the initial node.

20. The method of claim 17, wherein the storage management operation is a volume provisioning operation and the initial node corresponds with a volume created by the volume provisioning operation.
