Storage management method and storage management system
First Claim
1. A storage management method partitioning a physical resource and a logical resource in a storage subsystem, allocating a management user per partition unit, and performing partition management of each of said resources, the storage subsystem having a plurality of channel adapters coupled to a host computer and receiving data from the host computer, a cache memory temporarily storing data sent from the channel adapters, a plurality of disk adapters receiving data stored in the cache memory, a shared memory, a plurality of physical disks connected to said disk adapters and storing data sent from the disk adapters, and a switch for connecting said plurality of channel adapters, said plurality of disk adapters, said shared memory, and said cache memory, the storage management method comprising the steps of:
- storing, in said shared memory in said storage subsystem, program-product management information showing presence or absence of a program product that provides a configuration-changing function for each of said resources, said resources including partitioned channel adapters, a partitioned cache memory, and a logical disk drive group relating to a storage area of the physical disks, in a partition unit, the program product of said partition unit including a remote copy function;
receiving a request from said management user to access the configuration-changing functions provided by the program product of the partition unit of said management user;
in response to receiving said request, said program-product management information is referenced to determine and specify the partition unit of said management user, based on information contained in said request;
in response to an instruction received from said management user to execute a configuration-changing function provided by the program product of the partition unit of said management unit, referring to said program-product management information at the time of executing the configuration-changing function by said program product of each of said resources in the partition unit of said management user; and
restricting execution of the configuration-changing function of a resource without said program product.

Abstract
There is provided a storage management system capable of utilizing division management with enhanced flexibility and of enhancing security of the entire system, by providing functions by program products in each division unit of a storage subsystem. The storage management system has a program-product management table stored in a shared memory in the storage subsystem and showing presence or absence of the program products, which provide management functions of respective resources to respective SLPRs. At the time of executing the management functions by the program products in the SLPRs of users in accordance with instructions from the users, the storage management system is referred to and execution of the management function having no program product is restricted.

5. A storage management system partitioning a physical resource and a logical resource in a storage subsystem, allocating a management user per partition unit, and performing partition management of each of said resources, the storage subsystem having a plurality of channel adapters coupled to a host computer and receiving data from the host computer, a cache memory temporarily storing data sent from the channel adapters, a plurality of disk adapters receiving data stored in the cache memory, a plurality of physical disks connected to said disk adapters and storing data sent from the disk adapters, a shared memory, and a switch for connecting said plurality of channel adapters, said plurality of disk adapters, said shared memory, and said cache memory, the storage management system comprising:
-
program-product management information stored in said shared memory in said storage subsystem and showing presence or absence of a program product that provides a configuration-changing function of each of said resources, said resources including partitioned channel adapters, a partitioned cache memory, and a logical disk drive group relating to a storage area of the physical disks, in a partition unit, the program product of said partition unit including a remote copy function, wherein, in response to receiving a request from said management user to access the configuration-changing functions provided by the program product of the partition unit of said management user, said program-product management information is referenced to determine and specify the partition unit of said management user, based on information contained in said request, and wherein, in response to an instruction received from said management user to execute a configuration-changing function provided by the program product of the partition unit of said management user, at the time of executing the configuration-changing function by said program product of each of said resources in the partition unit of said management user, said program-product management information is referenced to restrict execution of the configuration-changing function of a resource without said program-product management information. - View Dependent Claims (6, 7, 8, 9, 10)
