Computer system and a method of assigning a storage device to a computer
First Claim
1. A computer system comprising:
- first computers;
a storage system comprising disks, a disk controller coupled to said disks, and ports communicatively coupled to said first computers; and
a second computer communicatively coupled to said storage system, wherein said second computer is configured to;
(a) receive a device assignment request for one of said first computers;
(b) prepare a device in said storage system satisfying the received request;
(c) set an access permission for an access from said one of said first computers to the prepared device by informing said storage system of an identification associated with said one of said first computers, based on the received device assignment request.

Abstract
A computer system which has a plurality of computers and a storage device subsystem connected to the plurality of computers. The storage device subsystem has a plurality of storage devices and a plurality of interfaces, through which the subsystem is connected to the computers. One of the plurality of computers has a management means for holding therein data indicative of the storage devices and a connection relationship between the computers and storage device subsystem. Each computer, when wanting a new device, informs the management means of its capacity and type. The management means receives its notification and selects one of the storage devices which satisfies the request. And the management means instructs the storage device subsystem to set predetermined data in such a manner that the computer can access the selected device. The management means also returns predetermined data to the computer as a device assignment requester, the assignment requester computer modifies setting thereof to allow the computer in question can use the assigned device.
