Abstract: PROBLEM TO BE SOLVED: To provide a technique for executing copying operation. SOLUTION: A fast reverse restore command showing a new source and a new target is received, the new source is an original target, and the new target is an original source. A synchronous scan is executed on the new target. A new target structure associated with the new target is updated, by using a new source structure associated with the new source. This technique for executing copying operation is provided, wherein an instantaneous virtual copy from the new target to the new source is executed, thereafter, a fast reverse restore command is received, and the fast reverse restore command is executed, before a background copy is executed, by the instantaneous virtual copy.

Abstract: Provided are a method, system, and program for forming a consistency group of data. Information is provided on a consistency group relationship indicating a plurality of slave controllers and, for each indicated slave controller, a slave storage unit managed by the slave controller. A command is transmitted to each slave controller in the consistency group relationship to cause each slave controller to transmit data in the slave storage unit to a remote storage in a manner that forms the consistency group. A determination is made as to whether all the slave controllers successfully transmitted the data in the slave storage units that is part of the consistency group to the remote storage.

Abstract: Provided are a method, system, and article of manufacture for splitting writes between a storage controller and replication engine. A splitter executing in a storage controller manages access to primary volumes. An initialization command is received to communicate with a replication engine. A replication command is received for one primary volume and the primary volume is indicated as subject to replication. A write request is received to write data to a target primary volume of the primary volumes that is indicated as subject to the replication. The data in the write request is written to the target primary volume. The data in the write request is sent to the replication engine. The replication engine executes a copy services function associated with the target primary volume to write the data to a replication engine volume.

Abstract: Es werden ein Computerprogrammprodukt, ein System und ein Verfahren bereitgestellt zum Ausführen eines Failover zwischen einem ersten Speichersystem und einem zweiten Speichersystem. Daten werden zwischen dem ersten Speichersystem und dem zweiten Speichersystem synchronisiert. Ein Failover wird von dem ersten Speichersystem zu dem zweiten Speichersystem als Reaktion auf ein Failover-Ereignis in dem ersten Speichersystem ausgeführt, während die Daten synchronisiert werden. Als Reaktion auf das Failover-Ereignis wird festgestellt, dass eine erste Speichereinheit des ersten Speichersystems nicht funktionsfähig ist und eine zweite Speichereinheit des ersten Speichersystems funktionsfähig ist. Als Reaktion auf ein Feststellen, dass die zweite Speichereinheit funktionsfähig ist, wird ein Neusynchronisieren ausgelöst zum Kopieren von Updates zu einer zweiten Speicherenheit des ersten Speichersystems durch Spiegeln der zweiten Speichereinheit des zweiten Speichersystems zu der zweiten Speichereinheit des ersten Speichersystems.

Abstract: Method, System, and Article of Manufacture for Consistent Copying of Storage Volumes Provided are a method, system, and article of manufacture for copying storage. Copy operations are performed logical on source storage volumes (108a, 108b) to copy to logical target storage volumes (112a, 112b), wherein the copy operations create a consistent copy of the logical storage volumes (108a, 108b) in the logical target storage volumes (112a, 112b). While performing a copy operation to copy from one logical source storage volume (108a) to one target logical storage volume (112a), a write operation is restricted from being performed on the one logical source storage volume (108a), until the copy operations have been performed on the logical source storage volumes.
