Management of object location in hierarchical storage

A computer system for managing a location of an object in a storage system having hierarchical storage, the hierarchical storage including a plurality of storage layers, the computer system comprising:

• a memory storing program instructions;
• one or more interfaces in communication with the plurality of the storage layers and a network;
• and
• a processor in communications with the memory and the one or more interfaces, wherein, by executing the program instructions, the processor is configured to:
• transmit a get-list request for viewing contents of a designated directory on the hierarchical storage;
• receive a response to the get-list request, the response including a list of objects in the designated directory, the response also listing each storage layer corresponding to the objects;
• in response to receiving the response, output the list of the objects with their corresponding storage layers;
• receive a select request to select a different storage layer for one of the objects;
• transmit the select request to the storage system for invoking a migration of the selected one of the objects to the different storage layer;
• receive a second response from the storage system indicating the selected one of the objects is stored in the different storage layer;
• and
• in response to receiving the second response, output an updated list of the objects with their corresponding storage layers.

A computer program product for managing a location of an object in a storage system having a hierarchical storage, the hierarchical storage including a plurality of storage layers, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computer system to cause the computer system to perform a method comprising:

• transmitting, by the computer system, a get-list request for viewing contents of a designated directory on the hierarchical storage;
• receiving, by the computer system, a response to the get-list request, the response including a list of objects in the designated directory, the response also listing each storage layer corresponding to the objects;
• in response to receiving the response, outputting, by the computer system, the list of the objects with their corresponding storage layers;
• receiving, by the computer system, a select request to select a different storage layer for one of the objects;
• transmitting, by the computer system, the select request to the storage system for invoking a migration of the selected one of the objects to the different storage layer;
• receiving, by the computer system, a second response from the storage system indicating the selected one of the objects is stored in the different storage layer;
• and
• in response to receiving the second response, outputting, by the computer system, an updated list of the objects with their corresponding storage layers.
