1. A computer system comprising:
- a plurality of computers;
a storage system including a plurality of logical units and at least one interface control circuit coupled to the plurality of computers; and
a management computer coupled to the storage system, said management computer including a memory that stores a relation between a user name and logical unit identification information identifying a private logical unit of a user indicated by the user name;
wherein each of the plurality of logical units is a private logical unit of a predetermined user,wherein the management computer is arranged to receive a user name and computer identification information identifying a computer, refer to the memory to find the logical unit identification information corresponding to the received user name, and transmit the received computer identification information associated with the received user name and found logical unit identification information to the storage system, andwherein the storage system is arranged to receive the computer identification information and logical unit identification information transmitted by the management computer and, in response to receipt of the computer identification information and logical unit identification information, to permit the computer identified by the received computer identification information to access the at least one private logical unit indicated by the received logical unit identification information.

6. A computer program product for a system that includes a plurality of computers and a storage system having a plurality of logical units and at least one interface control circuit coupled to the plurality of computers, the computer program product comprising:
-
a recording medium; means, recorded on the recording medium, for causing a processor to manage a relation between a user name and logical unit identification information identifying a private logical unit of the user indicated by the user name, wherein the plurality of logical units includes the private logical unit, and said relation is stored in a memory connected to the processor; means, recorded on the recording medium, for causing the processor to find the logical unit identification information corresponding to a received user name, from the relation stored in the memory; and means, recorded on the recording medium, for causing the processor to transmit received computer identification information associated with the received user name, and the found logical unit identification information, to the storage system, so that the storage system thereby receives the computer identification information and logical unit identification information transmitted by the processor and, in response to receipt of the computer identification information and logical unit identification information, the storage system permits the computer identified by the received computer identification information to access the private logical unit identified by the received logical unit identification information.

7. A computer system comprising:
-
a plurality of computers; a storage system including a plurality of logical units and at least one interface control circuit coupled to the plurality of computers; and a computer program stored in a computer readable memory, which causes a processor to manage a relation between a user name and logical unit identification information identifying a private logical unit of the user indicated by the user name, wherein the plurality of logical units includes the private logical unit, and said relation is stored in a memory connected to the processor; wherein the computer program causes the processor to find the logical unit identification information corresponding to a received user name, from the relation stored in the memory, and to transmit received computer identification information associated with the received user name, and the found logical unit identification information, to the storage system, and wherein the storage system is arranged to receive the computer identification information and logical unit identification information transmitted by the processor and, in response to receipt of the computer identification information and logical unit identification information, permit the computer identified by the received computer identification information to access the private logical unit identified by the received logical unit identification information. - View Dependent Claims (8, 9, 10, 11)
