Data processing method with restricted data arrangement, storage area management method, and data processing system

A data processing system having a storage device, wherein said storage device includes two or more storage areas;

• wherein said data processing system includes a first storage area that is associated with a data range in which data can be located, and a second storage area that is associated with range information which specifies a storage area location/attribute;
• wherein said data processing system judges whether or not said first storage area associated with said data range can be located in the second storage area associated with said range information according to a comparison of said data range and range information;
• wherein said data processing system outputs said judging results;
• wherein a data processing system defines data in a copy-source storage area and a copy-destination storage area;
• wherein a data processing system accepts a request to copy the data that is included in said copy-source storage area to said copy-destination storage area from said copy-source storage area;
• wherein a data processing system copies said data in said copy-source storage area to said copy-destination storage area judging from the output result of said data processing system;
• wherein said data range is designated for data in a copy-source storage area, and said range information is designated for a copy-destination storage area.

A storage device including two or more storage areas;

• wherein said storage device includes a first storage area that is associated with a data range in which data can be located, and a second storage area that is associated with range information which specifies a storage area location/attribute;
• wherein said storage device judges whether or not said first storage area associated with said data range can be located in the second storage area associated with said range information according to a comparison of said data range and range information;
• wherein said storage device outputs said judging results;
• wherein said storage device designates a capacity for storing the data;
• wherein said storage device judges whether or not said storage area has free space equal to or greater than said designated capacity;
• wherein said storage device outputs the result of whether or not said storage area has free space equal to or greater than said designated capacity.

A data processing system comprising:

• a source storage device which has a volume including a copy-source storage area;
• a destination storage device which has a volume including a copy-destination storage area;
• wherein said source storage device and said destination storage device are coupled to each other through communication devices;
• wherein said source storage device and said destination device have a memory storing a data copy program;
• wherein the memory of said source storage device stores possible data arrangement range information for the data in said copy-source storage area, and volume range information for said copy-destination storage area;
• wherein said destination storage device copies transmits said volume range information for said copy-destination storage area to said source storage device, and said source storage device judges whether or not the range indicated by said possible data arrangement range information for the data in said copy-source storage area is within the range indicated said volume range information for said copy-destination storage area by referring to said possible data arrangement range information stored in said memory;
• and
• wherein said source storage device copies data from said copy source storage area to said copy-destination storage area in case of judging that the range indicated by said volume range information for said copy-destination storage area is within the range indicated by said possible data arrangement range information for the data in said copy-source storage area.
