Storage apparatus, computer system, and control method for storage apparatus |
摘要 |
A storage apparatus of an embodiment of the invention including one or more storage drives for providing real storage resources and a controller for controlling the one or more storage drives and accesses from a host computer. The controller initializes real storage resources and manages the initialized real storage resources. The controller receives an instruction for allocating an initialized real storage resource to a first virtual storage resource accessed by the host computer. In response to the instruction, the controller allocates a first initialized real storage resource which has been initialized in advance prior to the instruction to the first virtual storage resource. |

1. A storage apparatus comprising:
one or more storage drives for providing real storage resources; and a controller configured to control the one or more storage drives and accesses from a host computer, wherein the controller is configured to initialize real storage resources and to include management information for managing the initialized real storage resources; wherein the controller is configured to receive an instruction for allocating an initialized real storage resource to a first virtual storage resource accessed by the host computer; wherein, in response to the instruction, the controller is configured to receive a determination whether unallocated initialized real storage resources exist with reference to the management information; and wherein, when the determination is positive, the controller is configured to allocate a first initialized real storage resource selected from the management information to the first virtual storage resource without further initializing the selected first initialized real storage resource. |
