Storage system and controlling method thereof, and device and recording medium in storage system

A control method in a virtualization system coupled to a host computer and a disk array system and having a virtualization device and a management device, said virtualization device having a virtual storage volume corresponding to a logical volume, which is related to a plurality of disk drives in said disk array system, said control method comprising:

• mapping a first information regarding said logical volume and to a second information regarding said virtual storage volume, said first information including information of a first Logical Unit Number (LUN) regarding said logical volume, said second information including information of a second LUN regarding said virtual storage volume;
• transferring said mapped first and second information between said virtualization device and said management device;
• receiving a data input/output request, sent from said host computer, and targeted to said virtual storage volume;
• changing a LUN, which is included in said data input/output request and corresponds to said second LUN, to said first LUN, which corresponds to said second LUN based on said mapped first and second Information;
• and
• transferring said changed data input/output request to said logical volume so that said disk array system performs inputting/outputting of data corresponding to said data input/output request to/from said disk drives corresponding to said logical volume.

A control method in a virtualization system coupled to a host computer and a disk array system and having a virtualization device and a management device, said virtualization device having a virtual storage volume corresponding to a logical volume, which is related to a plurality of disk drives in said disk array system, said control method comprising:

• storing a relationship information related a first information regarding said logical volume to a second information regarding said virtual storage volume, said first information including information of a first Logical Unit Number (LUN) regarding said logical volume, said second information including information of a second LUN regarding said virtual storage volume;
• transferring said stored relationship information between said virtualization device and said management device:
• receiving a data input request, including a LUN corresponding to said virtual volume and data and sent from said host computer and targeted to said virtual volume;
• changing said LUN corresponding to said virtual volume included in said data input request to said first LUN, which corresponds to said second LUN included in said second information;
• and
• transferring said changed data input request to said logical volume so that said disk array system performs inputting of said data corresponding to said data input request to said disk drives related to said logical volume.

• storing a relationship information related a first Logical Unit Number (LUN) regarding said logical volume to a second second LUN regarding said virtual storage volume;
• transferring said stored relationship information between said virtualization device and said management control device;
• receiving a data output request sent from said host computer to said virtual volume;
• converting a LUN, which is included in said data output request and corresponds to said second LUN, to said first LUN, which corresponds to said second LUN, based on said relationship information;
• sending said changed data output request to said disk array system so that said disk array system performs outputting of data corresponding to said data output request from said disk drives corresponding to said logical volume;
• receiving a data output response, which includes said data of said data output request, from said disk array system;
• and
• sending said data of said data output request to said host computer.
