Apparatus and method for partitioning and managing subsystem logics
First Claim
1. A disk array system, comprising:
- a port receiving data from an information processing device;
a first controller transferring data received by said port;
a memory storing data in accordance with the transferring performed by said first controller;
a second controller transferring data stored in said memory;
a plurality of disk drive groups to which data transferred by said second controller is stored and having a plurality of storage regions in a plurality of disk drives;
a plurality of logical units being addresses to which data is sent from said information processing device and corresponding to said storage regions; and
a plurality of resource groups each having a first plural kinds of resources among said ports, said first controller, said memory, said second controller, said disk drive groups, and said logical units,wherein, in order to change configuration in a first resource group of said resource groups, a first resource in said first resource group is permitted to change from a first state of relating to a second resource in said first resource group into a second state of relating to a third resource in said first resource group without being permitted to change to a third state of relating to a fourth resource in a second resource group of said resource groups.

Abstract
A subsystem logics partitioning and managing apparatus comprises a recognition unit for recognizing logical and physical resources that constitute a subsystem a partition definition table in which the logical and physical resources in the subsystem are assigned for each user at an interface level at which a storage configuration can be referenced by a storage management program an account table in which an account is set for each user-specific partition defined in the partition definition table a receiving unit for receiving a user account transmitted from an information processing unit and checking the received user account against the account table, to recognize a partition that corresponds to the user and a unit for outputting, at a GUI level, logical resources and physical resources that are contained in the recognized partition to an output interface as a resource configuration in the subsystem.
