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.
