Methods, systems, and apparatus to interface with storage objects

A system, comprising:

• a processor;
• and
• memory coupled to the processor, wherein the memory stores instructions executable by the processor to:
• provide a storage mapping application programming interface (API) library including a plurality of functions;
• generate, using a first function of the plurality of functions, a first mapping of a storage object to physical storage, 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 first storage management layer at a storage environment where the data of the storage object is stored, and a second node representing a second storage management layer at the storage environment;
• obtain, using one or more functions of the plurality of functions, first metadata associated with the first storage management layer and second metadata associated with the second storage management layer;
• obtain, using a second function of the plurality of functions, a configuration identifier associated with the storage object;
• generate, using a third function of the plurality of functions, 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, receive a notification 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;
• and
• in response to said notification, generate using the first function, 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.

A computer readable medium comprising program instructions, wherein the instructions are computer executable to:

• generate, at a first storage 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;
• obtain, at the first storage environment, a configuration identifier associated with the storage object obtain, first metadata associated with the file system layer and second matadata associated with the volume manager layer;
• generate, 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, receive 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, generate 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
• access, from the first storage environment, the at least a portion of the data from the second physical storage location using the new mapping.
