Abstract
In one mode, a management calculator is connected to a host calculator and a storage device, and stores, in a memory, composition information and function setting information. The composition information shows multiple logic storage regions provided by the storage device, and objects that are stored in one logic storage region from among the multiple logic storage regions and that are executed by the host calculator, the logic storage regions and the objects being shown in association with one another. Meanwhile, the function setting information shows storage functions set for the logic storage regions.
Claims11
A management computer connected to a host computer and a storage device, comprising:
- a memory that stores configuration information showing a plurality of logical storage areas provided by the storage device linking to an object stored in a single logical storage area among the logical storage areas and executed by a host computer, and function setting information showing a storage function set in the logical storage areas;
- and
- a CPU connected to the memory that detects a change in the resource allocation to the first object by the host computer;
- searches the structural information and the function setting information, and acquires setting information of a storage function for the first logical storage area allocated to the first object prior to the resource allocation change;
- decides whether or not an effect has occurred at provision of the storage function relating to the first object due to a change in the resource allocation;
- and
- outputs the decision results.
A management method for a management computer connected to a host computer and a storage device, the method comprising:
- detecting a change in the resource allocation to the first object by the host computer;
- checking the configuration information that shows a plurality of logical storage areas provided by the storage device linked to an object stored in a single logical area among the plural logical storage areas and executed by a host computer, and function setting information that shows storage functions set in the logical storage areas, and acquiring setting information for storage functions in the first logical storage area allocated to the first object prior to the change in the resource allocation;
- deciding whether or not an effect has occurred in the providing of a storage function relating to the first object due to a change in the resource allocation;
- and
- outputting the decision results.
