Patent ID: 8006060

Claim:
A path creation support apparatus, which is an apparatus for supporting the creation of an access path from a host to a logical volume inside a storage system, a plurality of the access paths being grouped together on the basis of the type of operating system (OS) of the host that utilizes the access path the path, creation support apparatus comprising: a group information acquisition unit for acquiring group information from the storage system, the group information showing the group to which the access path utilized by the host belongs; a group information storage unit for storing the acquired group information and the type of OS of the host, which is associated with the acquired group information; a path creation indication unit which, upon receipt of an access path creation start request: acquires group information from the group information storage unit, the group information associated with the type of OS of the host which is to carry out the access path creation; and sends an access path creation indication to the host and the storage system which specifies a parameter, the access path creation start request, and the acquired group information; a logical volume information acquisition unit for acquiring logical volume information from the storage system, the logical volume information showing respective logical volumes that can be provided to the host by the storage system, and the residual capacities of the respective logical volumes; a logical volume information storage unit for storing the acquired logical volume information and the residual capacities of the logical volumes associated with the acquired logical volume information; and a logical volume decision unit for deciding a logical volume to be allocated to a created access path based on the residual capacities of the respective logical volumes stored in the logical volume information storage unit, wherein the access path creation indication further specifies logical volume information showing the logical volume decided by the logical volume decision unit.
