摘要： A data management apparatus of a computer system comprises, as a retention rule for volume data, change-time identification information for identifying a point-in-time for changing a logical unit, and migration-destination unit specification information for specifying a migration-destination logical unit. An edge storage apparatus stores first identification information, which enables the identification of volume data in a logical unit, and second identification information, which enables the identification of a logical unit in a storage system after associating the first identification information and the second identification information with each other. A data management apparatus (A1) transfers the volume data from a migration-source logical unit to the migration-destination logical unit conforming to the migration-destination unit specification information subsequent to a point-in-time identified in accordance with the change-time identification information. The edge storage apparatus (B1) associates the second identification information, which enables the identification of the migration-destination logical unit, with the first identification information, and stores the associated information in a storage device.

摘要： Information system, including: first and second storage apparatuses connected to a host computer and including volumes designated by a common volume identifier, but being accessible via differing paths of differing priorities. A failure detection storage apparatus connected to the storage apparatuses includes a third volume. Any I/O request designating the common volume identifier, is first sent to the first volume though the first access path, but upon error is then sent to the second volume thorough the second access path. The first or second storage apparatus detecting failure stores, in the third volume, a failure information flag. Upon receiving an I/O request through the second access path, the second storage apparatus determines whether the failure information flag is stored in the third volume, and sends an error reply of the I/O request to the host computer if the failure information flag is stored in the third volume.

摘要： There is disclosed a data storage system used in a computer environment where there are plural host computers and plural storage array controllers. When a remote copy is made while assuring the order of writing across plural storage array controllers, one of the host computers gains copy information about all the storage array controllers associated with the remote copy as a representative. The representative one of the storage array controllers collects and stores copy statuses which are individually managed by the storage array controllers for which a remote copy is made. The host computer gains the copy statuses from the representative controller using an instruction to gain the copy statuses.

摘要： A first storage system misrepresents an identifier of the storage system and an identifier of a volume and provides the host computer with a first volume. A second storage system misrepresents an identifier of the storage system and an identifier of a second volume as being identical to those misrepresented by the first storage system and provides the host computer with a second volume. A management computer acquires, upon detection of a failure in an access, a status of copying, a status of the first storage system, and a status of the second storage system and controls an access from the host computer with reference to the plurality of acquired statuses. Accordingly, even when a fault occurs in one of the two storage systems, a network that connects the two storage systems, or the like, the host computer can access to latest data.

摘要： Provided are a method, system, and article of manufacture for managing consistency groups using heterogeneous replication engines replicating data. A common linkage manager issues a prepare to create consistency group command to a first replication manager and a second replication manager, wherein the first and second replication managers issue create consistency group commands to first and second replication engines, respectively, to form a consistency group of data at a first source storage and a second source storage to copy to a first target storage and second target storage, respectively. The first and second replication managers form a first consistency group and a second consistency group of data from the first and second source storages, respectively, that are consistent as of a point-in-time in response to the create consistency group command; transmitting, by the first and second replication managers, the data in the formed first and second consistency groups to a first journal and second journal, respectively. The first and second replication managers commit the data in the first and second consistency groups in the first and second journals to the first and second target storages, respectively, in response to the first and second replication managers receiving a commit command.

摘要： Composition of a consistency group is changed easily without releasing a volume pair of the consistency group concerning a remote copying system and a remote copying method using a sequence number. In order to change the composition of the consistency group, predetermined data sent from a data sending side after the relevant change is received. At that time, a reflection operation of the predetermined data on a logical storage area is started on a data receiving side after reflection of the predetermined data sent from the data sending side before the relevant change on the logical storage area is terminated.

摘要： In the data transfer method between a couple of computer nodes in the related art, an overhead for the waiting between programs to conduct the data transfer is considerably large.In the present invention, a first program to transmit data stores the data to the main storage area in the desired time interval. A second program to receive data refers to the above area using RDMA in the desired time interval. Otherwise, the second program to receive data refers to the main storage in the desired time interval. A first program to transmit data stores data to above area using RDMA in the desired time interval. Moreover, in order to detect the passing between the write and read operations, an identifier is provided to each record and the access sequence of the identifier and record is inverted in the read and write operations. Or, an identifier and an error checking code are added to each record.
