Storage management method and storage management system
First Claim
1. A storage management method dividing a physical resource and a logical resource in a storage subsystem, allocating a user per division unit, and performing division management of each of said resources, the storage subsystem having a plurality of channel adapters, a plurality of disk adapters, a shared memory, a cache memory, a physical disk connected to said 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, a program-product management table showing presence or absence of a program product providing a management function of each of said resources to the division unit;
referring to said program-product management table at the time of executing a management function by said program product in the division unit of said user in accordance with an instruction from said user;
restricting execution of the management function without said program product; and
at the time of having an instruction of a configuration alteration request of each of said resources from said user, returning, to said user, a configuration-unalterable error if a resource of the configuration alteration request instructed is not a resource in the division unit of said user.

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.

2. A storage management system dividing a physical resource and a logical resource in a storage subsystem, allocating a user per division unit, and performing division management of each of said resources, the storage subsystem having a plurality of channel adapters, a plurality of disk adapters, a shared memory, a cache memory, a physical disk connected to said 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 system comprising:
-
a program-product management table stored in said shared memory in said storage subsystem and showing presence or absence of a program product providing a management function of each of said resources to said division unit, and a management client connected to said storage subsystem, said user performing management for each of the resources in said division unit by using the management client, wherein, at the time of executing the management function by said program product in the division unit of said user in accordance with an instruction from said user, said storage management system is referred to restrict execution of the management function without said program-product management table, wherein, at the time of displaying, from said management client, an operation screen of a management function by said program product, said program-product management table is referred to and the operation screen of only the management function having said program product is displayed, and wherein, at the time of having an instruction of a configuration alteration request for each of said resources from said management client, if a resource of the instructed configuration alteration request is not a resource in the division unit of said user, a configuration-unalterable error is returned to said user.

3. A storage management system dividing a physical resource and a logical resource in a storage subsystem, allocating a user per division unit, and performing division management of each of said resources, the storage subsystem having a plurality of channel adapters, a plurality of disk adapters, a shared memory, a cache memory, a physical disk connected to said 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 system comprising:
-
a program-product management table stored in said shared memory in said storage subsystem and showing presence or absence of a program product providing a management function of each of said resources to said division unit, wherein, at the time of executing the management function by said program product in the division unit of said user in accordance with an instruction from said user, said storage management system is referred to restrict execution of the management function without said program-product management table, and wherein, at the time of having an instruction of a configuration alteration request for each of said resources from a host computer of said user, the host computer being connected to the division unit of said storage subsystem, if a resource of the instructed configuration alteration request is not a resource In the division unit to which said host computer is connected, a configuration-unalterable error is returned to said host computer.
