Patent ID: 7783856

Claim:
A computer system comprising: a server computer comprising a first CPU and a plurality of I/O adaptors; a storage system coupled to the server computer, the storage system having a second CPU, a plurality of disk drives, and a plurality of channel adaptors to receive data input/output requests from the server computer; and a control terminal coupled to the server computer and the storage system, wherein the first CPU of the server computer processes a first hypervisor operating a plurality of virtual machines, each of the plurality of virtual machines having a virtual I/O adaptor corresponding to one of the plurality of I/O adaptors, wherein the second CPU of the storage system processes a second hypervisor operating a plurality of virtual storages, each of the plurality of virtual storages having a virtual disk which is partitioned from the plurality of disk drives, and a virtual channel adaptor corresponding to one of the plurality of channel adaptors, wherein the control terminal collects server computer control information on a correspondence between a virtual I/O adaptor of one of the plurality of virtual machines and one of the plurality of I/O adaptors, and storage system control information on a correspondence between a virtual channel adaptor and one of the plurality of channel adaptors, wherein the control terminal stores control information on a relation between one of the plurality of the virtual storages and one of the plurality of the virtual machines, and wherein the control terminal displays a particular virtual path established between a certain virtual I/O adaptor and a certain virtual channel adaptor with corresponding physical paths established between one of the plurality of I/O adaptors and one of the plurality of channel adaptors, according to the server computer control information and the storage system control information and the control table.
