Storage system and management method thereof

A storage system comprising:

• a first storage apparatus including a first controller and a plurality of first storage devices, wherein the first controller manages a first virtual storage apparatus having a first logical storage area, to which the first controller permits access from a first server by referring first management information, prepared on at least one of said first storage devices and a second virtual storage apparatus having a second logical storage area, to which the first controller permits access from a second server by referring second management information, prepared on at least one of said first storage devices;
• and
• a second storage apparatus including a second controller, and a plurality of second storage devices;
• wherein when the first virtual storage apparatus is copied from the first storage apparatus to the second storage apparatus, the first controller copies the first logical storage area and the first management information to the second storage apparatus, and the second controller creates the copied first virtual storage apparatus in the second storage apparatus, the copied first virtual storage apparatus including the copied first logical storage area, to which the second controller permits access from the first server by referring the copied first management information, prepared on at least one of the second plurality of second storage devices.

A storage system comprising:

• a first storage apparatus including a plurality of first storage devices, and a first controller which manages:
• a first virtual storage apparatus having a first logical storage area prepared on at least one of said first storage devices, and a second virtual storage apparatus having a second logical storage area prepared on at least one of said first storage devices;
• and
• a second storage apparatus including a plurality of second storage devices, and a second controller;
• wherein the first storage apparatus has first management information corresponding to an access right of a first client to the first logical storage area, and second management information corresponding to an access right of a second client to the second logical storage area, and
• wherein when the first virtual storage apparatus is copied from the first storage apparatus to the second storage apparatus, the first controller copies the first logical storage area and the first management information to the second storage apparatus, and the second controller creates the copied first virtual storage apparatus in the second storage apparatus, the copied first virtual storage apparatus including the copied first logical storage area, to which access right of the first client is set by the second controller using the copied first management information, prepared on at least one of the plurality of second storage devices.

A method for a first storage apparatus including a plurality of first storage devices and coupled to a second storage apparatus including a plurality of second storage devices, the method comprising:

• managing a first virtual storage apparatus which has a first logical storage area, to which a first server is permitted to access by referring to first management information, prepared on at least one of said first storage devices;
• managing a second virtual storage apparatus which has a second logical storage area, to which a second server is permitted to access by referring to second management information, prepared on at least one of said first storage devices;
• and
• copying, when the first virtual storage apparatus is copied from the first storage apparatus to the second storage apparatus, the first logical storage area and the first management information to the second storage apparatus to create copied first virtual storage apparatus in the second storage apparatus, the copied first virtual storage apparatus including the copied first logical storage area, to which the first server is permitted to access by referring to the copied first management information, prepared on at least one of the second plurality of second storage devices.

A method for a first storage apparatus including a plurality of first storage devices and coupled to a second storage apparatus including a plurality of second storage devices, the method comprising:

• managing a first storage apparatus including a plurality of first storage devices, and a first controller which manages:
• a first virtual storage apparatus having a first logical storage area prepared on at least one of said first storage devices, and a second virtual storage apparatus having a second logical storage area prepared on at least one of said first storage devices;
• managing first management information corresponding to an access right of a first client to the first logical storage area, and second management information corresponding to an access right of a second client to the second logical storage area;
• and
• copying, when the first virtual storage apparatus is copied from the first storage apparatus to the second storage apparatus, the first logical storage area and the first management information to the second storage apparatus to create the copied first virtual storage apparatus in the second storage apparatus, the copied first virtual storage apparatus including the copied first logical storage area, to which an access right of the first client is set by referring to the copied first management information, prepared on at least one of the plurality of second storage devices.
