Abstract: In order to manage and operate Pool created in storage system A and a virtual volume using Pool in storage system B, it is required to copy the virtual volume of storage system A into a virtual volume of storage system B and new storage regions for copy of virtual volume into storage system B are needed. Storage system B acquires configuration information of Pool and a virtual volume of storage system A and inputs a logical volume included in Pool of storage system A to storage system B based on the acquired configuration information. Storage system B transforms the acquired configuration information for use in storage system B and creates Pool and a virtual volume from the input logical volume based on the transformed configuration information.

Abstract: The present invention provides effective use of a storage resource in a system where a storage area of a logical volume is dynamically extended and reduced. In an information processing system including a management device communicably connected to a storage device that can dynamically change a storage capacity of a virtual volume allocated to a host computer, when a used amount of a certain storage pool exceeds a threshold set in the storage pool, the management device sends to the storage device, an instruction to migrate a predetermined number of virtual volumes, sequentially selected in ascending order of capacity increasing rate, so that another storage pool different from the certain storage pool may be used as a creation source. At this time, as a migration destination, the management device uses, the storage pool having, for example, an attribute of the storage resource identical to that of the certain storage device.

Abstract: A managing computer (manager) manages replication of data areas inside a storage or among storages. A storage volume management module of the manager manages policy of the volume and its properties. When replication of a volume is set, a volume of a replication destination appropriate for a volume of a replication source is generated using the policy and the properties to form a replication pair. A route management module of the manager and its volume management module bring the policy and the properties of the volumes, and the policies and conditions of lines into conformity with one another. When any fault occurs in a line route used for data transfer during replication of the volume, a separate line route is utilized, and a fault countermeasure is taken for replication of the volumes in accordance with the policy and properties of the volumes.
