Abstract: Provided are a method, system, and program for managing a relationship between one target volume and one source volume. For each of the source volume and target volume, the memory includes: (i) at least one element, wherein each element represents a range of sequential data units in the volume; (ii) at least one relationship entry, wherein each relationship entry represents one relationship; (iii) at least one element pointer associating one element with one relationship entry, wherein the data units represented by the element are part of the relationship represented by the relationship entry that the pointer associates with the element; and (iv) one relationship pointer for each relationship entry associating the relationship entry with volume metadata, wherein the volume metadata provides information on the relationship represented by the relationship entry.

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: A method for protecting data in storage systems includes receiving a command for writing data to a first storage location. A determination is made that previously written data is stored in the first storage location. The previously written data is copied to a second storage location, in response to determining that the previously written data is stored in the first storage location. The data is written to the first storage location, in response to copying the previously written data to the second storage location.
Abstract translation: 一种用于保护存储系统中的数据的方法包括：接收用于向第一存储位置写入数据的命令。 确定先前写入的数据被存储在第一存储位置。 响应于确定先前写入的数据被存储在第一存储位置，先前写入的数据被复制到第二存储位置。 响应于将先前写入的数据复制到第二存储位置，数据被写入到第一存储位置。

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.

Abstract: A system for asynchronously duplexing direct access storage device (DASD) data in a plurality of DASD subsystems has the advantage of decoupling the data duplexing operation from the DASD write I/O operation. This ensures the write does not incur unnecessary wait states in the subsystem. By establishing a sequence checkpoint at which time a set of information packets are grouped together and processed as a single sequence unit, this decoupling and independent operation takes place. Through this independence, data copying to a secondary location can take place without affecting the performance of the subsystems and also not affecting the corresponding integrity of the data that is being updated.
