Storage system management method, storage system, switch, and storage medium having a program

A storage system comprising:

• at least one storage device having
• at least one connection port, and
• at least one storage volume connected to
• each of said at least one connection port;
• and
• a switch having
• at least two switch ports to which said storage device can be connected via said connection port of the same,
• an output unit outputting, when a data frame is input to one of said switch ports, the data frame from either one of said switch ports connected to one of said connection port to which that data frame is to be sent according to a destination specified in that data frame,
• a memory storing a correspondence X that defines a correspondence between said destination and said connection port, and
• a processor receiving an update request that is input to said switch from outside and updating said correspondence X based on said update request.

A switch comprising:

• at least two switch ports to which at least one storage device having at least one connection port can be connected via said connection port of the same;
• an output unit outputting, when a data frame is input to one of said switch ports, the data frame from either one of said switch ports connected to one of said connection port to which that data frame is to be sent according to a destination specified in that data frame;
• a memory storing a correspondence X that defines a correspondence between said destination and said connection port;
• and
• a processor receiving an update request that is input to said switch from outside and updating said correspondence X based on said update request.

A computer-readable storage medium having a program recorded thereon, said program causing a switch provided in a storage system that includes

• at least one storage device having at least one connection port and at least one storage volume connected to each of said at least one connection port, and
• said switch having at least two switch ports to which said storage device can be connected via said connection port of the same and, when a data frame is input to one of said switch ports, being capable of outputting that data frame from either one of said switch ports connected to one of said connection port to which that data frame is to be sent according to a destination specified in that data frame
• to execute:
• storing a correspondence X that defines a correspondence between said destination and said connection port;
• receiving an update request that is input to said switch from outside;
• and
• updating said correspondence X based on said update request.

A computer-readable storage medium having a program recorded thereon, said program causing a management server provided in a storage system that includes

• at least one storage device having at least one connection port and at least one storage volume connected to each of said at least one connection port,
• a switch having at least two switch ports to which said storage device can be connected via said connection port of the same and, when a data frame is input to one of said switch ports, being capable of outputting that data frame from either one of said switch ports connected to one of said connection port to which that data frame is to be sent according to a destination specified in that data frame, and
• said management server connected to said switch for inputting said update request to said switch
• to execute:
• determining a transfer-source storage volume from which data is transferred and a transfer-target storage volume to which the data is transferred when performing an operational change to make data stored in one of said storage volume be stored in another said storage volume;
• storing a correspondence Y that defines a correspondence between said connection port and said switch port and a correspondence Z that defines a correspondence between said connection port and said storage volume;
• and
• creating said update request based on information about said transfer-source storage volume and said transfer-target storage volume that have been determined, said correspondence Y, and said correspondence Z.
