Patent ID: 8397047

Claim:
A recording medium storing a logical volume configuration information distribution program causing a computer to execute processing based on logical volume configuration information that defines a correspondence relation between a virtual storage area in a logical volume defined virtually and a real storage area in a storage unit, the logical volume configuration information is provided via a network to an access node that accesses the real storage area in response to an access request that specifies data in the virtual storage area, wherein the logical volume configuration information distribution program causes a computer to execute a process comprising: changing the correspondence relation between the virtual storage area of the logical volume and the real storage area in the storage unit in the logical volume configuration information; and referencing an access node list storage unit storing an access node list in which identification information of the access node is registered, and transmitting update information that indicates an updated correspondence relation concerning the virtual storage area whose correspondence relation with the real storage area has been changed, to the access node indicated in the access node list, via the network when the correspondence relation between the virtual storage area and the real storage area is changed, wherein the logical volume identification information used by the access node is set in the access node list, and wherein a load distribution program stored in the recording medium causes the computer to execute a process comprising: referencing the access node list, and transmitting the update information only to an access node that uses the logical volume whose correspondence relation between the virtual storage area and the real storage area has been changed when the update information is to be transmitted.
