ABSTRACT:
Provided is an environment that storage device configuration management can be efficiently done in a data center having a virtualization device. A SAN manager acquires configuration information from a device constituting a SAN and prepares a correspondence relationship between a host computer and a virtual volume in the SAN, and a corresponding relationship between the host computer and a real volume, depending upon the acquired information. Based on the corresponding relationship, the SAN manager outputs a correspondence relationship of between virtual and real volumes. Meanwhile, by interpreting a failure-notification message received from the devices of the SAN, detected and outputted is an influence upon an access to a real or virtual volume as to the failure. Furthermore, when a plurality of failure notifications are received from the devices connected to the SAN, a plurality of failure notifications are associatively outputted depending upon a correspondence relationship between real and virtual volumes.
