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.

Abstract: A processor implemented method for inferring storage topology of a host includes discovering, from a security group that contains an initiator port of the host, all initiator ports of the host and all target ports of a storage device. Identification is then made of a port in the security group through which access to the storage device is blocked. From the discovered ports not identified as blocked, available paths between the host and a volume exposed to the host by the storage device are detected.
