Processing method, storage system, information processing apparatus, and computer-readable storage medium storing program

A storage system comprising:

• a storage apparatus that stores data and executes processing on the data on the basis of first configuration information stored in a first configuration information storage section;
• and
• a plurality of information processing apparatuses connected to the storage apparatus via a first communication link,
• a first information processing apparatus of the plurality of information processing apparatuses comprising:
• a second configuration information storage section adapted to store second configuration information being a duplicate of the first configuration information;
• a first configuration information modification section adapted to modify first configuration information in the storage apparatus;
• a notification section adapted to notify, a second information processing apparatus of the plurality of information processing apparatuses in the storage system, of modified part information indicating a modified part in the first configuration information modified by the first configuration information modification section, the second information processing apparatus being connected to via a second communication link different from the first communication link and being different from the first information processing apparatus;
• a modified part information storage section adapted to store the modified part information notified by the second information processing apparatus;
• and
• an updating section adapted to update, prior to modifying the first configuration information in the storage apparatus, the modified part in the second configuration information indicated by the modified part information stored in the modified part information storage section, on the basis of the first configuration information.

An information processing apparatus connected, via a first communication link, to a storage apparatus that executes processing on data on the basis of first configuration information stored in a first configuration information storage section, the information processing apparatus comprising:

• a second configuration information storage section adapted to store second configuration information being a duplicate of the first configuration information;
• a first configuration information modification section adapted to modify first configuration information in the storage apparatus;
• a notification section adapted to notify a second information processing apparatus connected via a second communication link of modified part information indicating a modified part in the first configuration information modified by the first configuration information modification section;
• a modified part information storage section adapted to store the modified part information notified by the second information processing apparatus;
• and
• an updating section adapted to update, prior to modifying the first configuration information in the storage apparatus, the modified part in the second configuration information indicated by the modified part information stored in the modified part information storage section, on the basis of the first configuration information.

A computer-readable storage medium storing a program, the program makes a computer that is connected, via a first communication link, to a storage apparatus that executes processing on data on the basis of first configuration information stored in a first configuration information storage section, when executed, the program making the computer to function as:

• a second configuration information storage section adapted to store second configuration information being a duplicate of the first configuration information;
• a first configuration information modification section adapted to modify first configuration information in the storage apparatus;
• a notification section adapted to notify a second information processing apparatus connected via a second communication link of modified part information indicating a modified part in the first configuration information modified by the first configuration information modification section;
• a modified part information storage section adapted to store the modified part information notified by the second information processing apparatus;
• and
• an updating section adapted to update, prior to modifying the first configuration information in the storage apparatus, the modified part in the second configuration information indicated by the modified part information stored in the modified part information storage section, on the basis of the first configuration information.
