Patent ID: 7117505

Claim:
A method comprising: generating, at a first environment, a first mapping of a storage object to physical storage at a second storage environment, wherein the first mapping indicates a first physical storage location at which at least a portion of the data of the storage object is stored, and wherein the first mapping includes a plurality of nodes of a data structure including a first node representing a file system layer at the second storage environment and a second node representing a volume manager layer at the second storage environment; obtaining, at the first storage environment, a configuration identifier associated with the storage object, first metadata associated with the file system layer and second metadata associated with the volume manager layer; generating, from the first storage environment, a request to access the at least a portion of the data of the storage object, wherein the request includes the configuration identifier; in response to said request to access, receiving a notification at the first storage environment of a change of location of the at least a portion of the data if the physical storage location of the at least a portion of the data has changed; in response to said notification, generating a new mapping at the first storage environment, wherein the new mapping indicates that the at least a portion of the data is located at a second physical storage location; and accessing, from the first storage environment, the at least a portion of the data at the second physical storage location.
