Abstract:
1. A remote copy system, comprising: a first storage system; a second storage system connected to the first storage system; and a first operator interface for receiving the input of a prescribed type information element from an operator, wherein the first storage system comprises a plurality of first logical volumes, a plurality of first communication ports, and a first controller, wherein the second storage system comprises a plurality of second communication ports, and a second controller, wherein the first controller comprises: a first acquisition unit that acquires a plurality of first type information elements, which constitute a plurality of elements of second setting information; a first output unit that outputs the acquired plurality of first type information elements; a first input unit that inputs first setting information, comprising a plurality of second type information elements; and a first setting unit that executes a first setting required to construct a remote copy environment, based on the plurality of second type information elements, which are comprised in the first setting information, and the plurality of first type information elements, wherein the remote copy environment is an environment, which enables to copy data between a certain first logical volume of the plurality of first logical volumes and a certain second logical volume by way of a certain first communication port of the plurality of first communication ports and a certain second communication port of the plurality of second communication ports, wherein the second setting information is information, which is inputted to the second storage system, and is used in a second setting required for constructing the remote copy environment, wherein the first setting information is information, which is inputted to the first storage system, and is used in the first setting, and wherein the second controller comprises: a second input unit that inputs the second setting information, which comprises the plurality of first type information elements, and a prescribed type information element inputted to the first operator interface; a second setting unit that executes the second setting based on the plurality of first type information elements and the prescribed type information element; a second acquisition unit that acquires the plurality of second type information elements, which constitute the plurality of information elements of the first setting information; and a second output unit that outputs the acquired plurality of second type information elements, wherein the number of the prescribed types is a smaller number than the types of information elements required for constructing the remote copy environment, wherein the prescribed type information element is volume identification information of the certain first logical volume, wherein the first acquisition unit acquires a storage capacity of the certain first logical volume as the first type information element, wherein the second acquisition unit acquires volume identification information of a second logical volume, which is the certain second logical volume for configuring a volume pair with the certain first logical volume, and which has a storage capacity that is equal to or greater than the storage capacity of the certain first logical volume, and in the first setting, volume pair information, which comprises the volume identification information of the certain first logical volume and the volume identification information of the certain second logical volume, is set, wherein one second storage system is connected to a plurality of first storage systems, and the volume identification information is a volume number, and wherein the second acquisition unit, as a rule, acquires, as the volume number of the certain second logical volume, the same volume number as the volume number of the certain first logical volume, and as an exception to that rule, acquires a volume number that differs from the volume number of the certain first logical volume when the same volume number as the volume number of the certain first logical volume has already been set.
