Abstract:
1. A computer system comprising: a storage system configured to control read access or write access from a host computer to a storage device; and a management device configured to manage a plurality of resources for the storage system and a plurality of users sharing the storage system; wherein the storage system includes: a plurality of resource groups defined by grouping of the plurality of resources; a storage area for storing management information of the plurality of resource groups and association information between the plurality of resources and the plurality of resource groups; and a plurality of user groups defined by grouping of the plurality of users, each of the user groups being allocated to at least one of the plurality of resource groups; wherein based on a login of at least one user from among the plurality of users, the management device is configured to have the storage system execute an operation permitted by an authority granted to a user group among the plurality of user groups, to which the relevant user belongs, on the resource group allocated to the user group; wherein the storage system is divided into a plurality of virtual storage systems; wherein the plurality of users are set to each of the plurality of virtual storage systems; wherein each of the plurality of virtual storage systems is divided into a first resource group composed of only a logical resource allocated from the storage system and a second resource group having a physical resource so that the logical resource and the physical resource will not coexist in the same resource group; wherein the logical resource of the first resource group is set from the physical resource which is taken out of the second resource group; wherein a first user group from among the plurality of user groups is allocated to the first resource group; wherein a second user group is allocated to the first resource group having the logical resource and the second resource group having the physical resource such that, even though the logical resource and the physical resource do not coexist in the same resource group, the logical resource and the physical resource are shared by the plurality of user groups; and wherein an authority to create a new logical resource is granted to the first user group and the second user group, and the new logical resource to be added to the first resource group is set from the physical resource of the second resource group, the physical resource including a port for the host computer and a parity group of the storage device.
