摘要： In a storage system having a plurality of control units each connected with a plurality of disk units, it is provided that a replication is created in the volume of the disk units connected to different control units. The replication creation unit of a given control unit creates a replication in the volume of the disk unit connected to other control units in such a manner that the original volume information, the replication volume information in the control unit and information on the other control units are registered as volume pair information. Based on this volume pair information, a replication creation request is transmitted to the other control units.

摘要： A second storage maps a migration source volume to a virtual volume of a migration destination volume according to storage virtualization technology. A host system including a host switches an access path from an access path to the migration source volume to an access path to the migration destination volume. The second storage executes copy processing of migrating, from the migration source volume to the migration destination volume, data in an assigned area of a virtual volume according to thin provisioning of the migration source volume based on the information contained in the first thin provisioning information in the first storage, and copying that data from the migration destination volume to a virtual volume according to thin provisioning of a copy destination volume in the second storage. The second storage associates the virtual volume of the copy destination volume with the migration destination volume in substitute for the original virtual volume.

摘要： A plurality of global LDEV managed by a plurality of controller modules are provided above local LDEV under the control of each controller module. Each global LDEV is correlated to any of the plurality of local LDEV. The controller modules judge whether or not a local LDEV correlated to a global LDEV specified by an I/O request received from a host device or a first other controller module is a management target itself, and if the result of that judgment is affirmative, the controller modules access the local LDEV correlated to the specified global LDEV, while if the result of the judgment is negative, the controller modules transfer the received I/O request to a second other controller module.

摘要： When data in the first primary volume is migrated to the second primary volume, an access request from the host to the primary volume is transferred to the second primary volume. Further, the second storage system stores write data received from the host and data of the first primary volume received from the storage system, into the second primary volume. Out of data stored in the second primary volume, the second storage system sends data determined by management information received from the first storage system, to the third storage system.

摘要： A method for migrating from a source storage system to a target storage system includes defining a volume defined on a device to be migrated in the source storage system as an external volume to the target storage system; causing the host to access the volume on the drive to be migrated through an input/output port of the drive to be migrated as the external volume of the target storage system; blocking the other input/output port of the drive to be migrated while maintaining the access to the external volume of the target storage system; reconnecting the blocked input/output port with an interface in the target storage system; blocking the input/output port through which the external volume is being accessed, and connecting it with the interface in the target storage system; and implementing the drive to be migrated in the target storage system. Data is migrated from the source storage system to the target storage system on a drive basis while receiving read/write requests for the data from the host computer and continuously using some of the source storage system.

摘要： For a storage system having plural control units to which plural disk devices are connected, in the method for creating replication in a volume of the disk devices connected to different control units, when receiving update I/O of a replication source during an initial copy for replication, the reflection of update to the replication destination is performed on an extension of the same I/O. When a pair is divided after the completion of copying, the update position is retained on the differential bitmap disposed in the individual control units, and the differential bitmap is merged to one of the control units at a time of resynchronization to perform copy processing.

摘要： The present invention provides a method for migrating from a source storage system to a target storage system. The method comprises the steps of: defining a volume defined on a drive to be migrated in the source storage system as an external volume of the target storage system; causing the host to access the volume on the drive to be migrated through an input/output port of the drive to be migrated as the external volume of the target storage system; blocking the other input/output port of the drive to be migrated while maintaining the access to the external volume of the target storage system; reconnecting the blocked input/output port with an interface in the target storage system; blocking the input/output port through which the external volume is being accessed, and connecting it with the interface in the target storage system; and implementing the drive to be migrated in the target storage system. This method can be used to migrate data from the source storage system to the target storage system on a drive basis while receiving read/write requests for the data from the host computer and continuously using some of the source storage system.
