Computer system including a device with a plurality of identifiers
First Claim
1. A computer system comprising:
- a network file server controller to be coupled to a plurality of computers, said network file server controller receives an access request from said computers; and
a storage device coupled to said network file server controller, said storage device has a storage area configured with a plurality of disks for storing data in response to said access request and is allocated to a plurality of Internet Protocol (IP) addresses,wherein said storage area is divided into a plurality of regions,wherein said network file server controller has set therein relations so that a first IP address of said IP addresses is allocated to a first region of said regions and a second IP address of said IP addresses is allocated to a second region of said regions,wherein said network file server controller responds to said received access request, which includes an IP address, based on said relations set therein regarding the allocated IP addresses and said regions, andwherein said first IP address corresponds to a first operating system executed in a first computer of first plurality of computers and said second IP address corresponds to a second operating system executed in a second computer of said plurality of computers.

Abstract
A host computer is connected with a magnetic disk storage device by a SCSI bus. In the magnetic disk storage device, a plurality of partitions are set in a disk drive unit and have device identifiers (IDs) respectively allocated thereto as SCSI IDs=1, 2 and 3, which are supported by a disk controller. When the host computer has acquired the control, the SCSI bus through an arbitration and has selected, for example, the partition with the device identifier SCSI ID=1, the disk controller permits the host computer to access the partition in response to the selection. Since the partitions are different in attributes, properties etc., they seem to be magnetic disk storage device that are separate from one another when viewed from the host computer. Thus, the single magnetic disk storage device can be managed as a plurality of storage devices of different nature.
