1. A management system coupled to a computer system including one or more types of storage apparatuses comprising: a storage resource which stores management information; and a processor coupled to the storage resource, wherein the management information includes: (a) request/function correspondence information, which is information containing, for each request by an administrator to perform a function, information indicating a storage function required to achieve the function satisfying the administrator request; and (b) function information, which is information containing, for each storage apparatus included in the computer system, information indicating storage functions stored in each of the storage apparatuses, wherein the storage function is a function of a storage apparatus, and wherein the processor executes: (A) reception of the request of the administrator to perform the function, wherein when the function requested by the administrator is stored in a storage apparatus of the storage apparatuses, the processor executes the function, and wherein when the function requested by the administrator is not stored in a storage apparatus of the storage apparatuses, the processor executes identification of a substitute function for achieving the function by further executing: (A1) identification of the substitute function, which is an implementation pattern, of one or more implementation patterns, the implementation pattern being a system configuration including a storage apparatus having a storage function required to achieve a function satisfying the administrator request received in (A), based on the request/function correspondence information and the function information; and (A2) setup for achieving the function satisfying the administrator request received in (A), with respect to a specified implementation pattern, which is any implementation patter of the one or more implementation patterns identified in (A1).
