摘要： A plurality of upgraded components associated with an upgraded storage subsystem replaces a plurality of existing components associated with an existing storage subsystem. Support for a verify I/O command is created. A target volume is created in the upgraded storage subsystem having a same volume identification as a source volume. For a command received on the at least one of the plurality of upgraded components, the verify I/O command is invoked on at least one of a comparable one of the plurality of existing components. If the command is verified, the command is driven. The at least one of the plurality of upgraded components disguises a true volume identification of the target volume from the at least one of the plurality of existing components.

摘要： Exemplary methods, systems, and computer program product embodiments for migrating existing data from a source storage controller to a target storage controller, each associated with a data processing storage subsystem, using a processor device in communication with a memory device, are provided. The target storage controller is configured with at least one target volume having pass-through support to a source volume of the source storage controller. An input/output (I/O) path to the existing data through the target storage controller is configured. The I/O path is added to an existing I/O path connected to the existing data using an operating system (OS) operational on at least one host in communication between the source and target storage controllers. The OS is adapted for I/O multipath support. Upon completion of data migration, the existing I/O path is removed.

摘要： A system and method for providing on-line, real-time, transparent data migration from an existing storage device to a replacement storage device. The existing and replacement storage devices are connected as a composite storage device that is coupled to a host, network or other data processing system. The replacement storage device includes a table which identifies data elements that have migrated to the replacement storage device. When a host system makes a data transfer request for one or more data elements, the replacement storage device determines whether the data elements have been migrated. If the data elements have migrated, the replacement storage device responds to the data transfer request independently of any interaction with the existing storage device. If the data elements have not migrated, the replacement storage device migrates the requested data elements and then responds to the data request and updates the data element map or table. When not busy servicing other requests, the replacement storage device operates in a background mode to migrate data elements so the data migration can occur concurrently with and transparently to system operations.

摘要： Two data storage systems are interconnected by a data link for remote mirroring of data. Each volume of data is configured as local, primary in a remotely mirrored volume pair, or secondary in a remotely mirrored volume pair. Normally, a host computer directly accesses either a local or a primary volume, and data written to a primary volume is automatically sent over the link to a corresponding secondary volume. Each remotely mirrored volume pair can operate in a selected synchronization mode including synchronous, semi-synchronous, adaptive copy-remote write pending, and adaptive copy-disk. Direct write access to a secondary volume is denied if a “sync required” attribute is set for the volume and the volume is not synchronized. If a “volume domino” mode is enabled for a remotely mirrored volume pair, access to a volume of the pair is denied when the other volume is inaccessible. In a “links domino” mode, access to all remotely mirrored volumes is denied when remote mirroring is disrupted by an all-links failure. The domino modes can be used to initiate application-based recovery, for example, recovering a secondary data file using a secondary log file. In an active migration mode, host processing of a primary volume is concurrent with migration to a secondary volume. In an overwrite cache mode, remote write-pending data in cache can be overwritten. Write data for an entire host channel command word chain is bundled in one link transmission.
摘要翻译：两个数据存储系统通过用于数据远程镜像的数据链路相互连接。每卷数据被配置为本地，主要在远程镜像卷对中，或辅助在远程镜像卷对中。通常，主机直接访问本地或主卷，并且写入主卷的数据将通过链接自动发送到相应的辅助卷。每个远程镜像卷对可以在所选择的同步模式中操作，包括同步，半同步，自适应复制远程写入挂起和自适应复制盘。如果为卷设置了“需要同步”属性，并且卷未同步，则对副卷的直接写入访问被拒绝。如果对远程镜像卷对启用“体积多米诺骨牌”模式，则在其他卷无法访问时，对该卷的访问将被拒绝。在“连接多米诺骨牌”模式下，当远程镜像被全连接故障中断时，对所有远程镜像卷的访问被拒绝。多米诺骨牌模式可用于启动基于应用程序的恢复，例如，使用辅助日志文件恢复辅助数据文件。在主动迁移模式下，主卷的主机处理与迁移到辅助卷并发。在覆盖缓存模式下，高速缓存中的远程写挂起数据可以被覆盖。整个主机通道命令字链的写入数据捆绑在一个链路传输中。

摘要： A primary data storage system is linked to a geographically remote secondary data storage system for automatically maintaining a remote copy of the data in the primary storage. The primary data storage system controller uses write pending indicators to control and coordinate the remote copy process. In response to receipt of data from the host computer, a first write pending indicator is set to write the data into at least one primary data storage device, and a second write pending indicator is set to copy the data to the secondary data storage system controller. The first write pending indicator is reset after the data is written to the primary data storage device, and the second write pending indicator is reset after receiving an acknowledgement back from the secondary data storage system controller.

摘要： An apparatus and method for disk mapping and data retrieval includes a data storage medium on which has been stored a plurality of data records. Each record includes at least a record identification portion, for uniquely identifying each record from among the plurality of data records. The apparatus builds a record locator table in high speed semiconductor memory which comprises the unique record identifiers for the records on the storage medium as well as a record locator index generated by the apparatus, which indicates the address of the data record on the storage medium. Data retrieval is facilitated by first searching the record locator table in high speed semiconductor memory for a requested data record. Utilizing the record locator index associated with the requested data record, the system directly H: accesses the requested data record on the storage medium thereby minimizing storage medium search time. Also disclosed is an apparatus and method for converting CKD formatted data records to FBA formatted disk drives and for building and compressing the “count” portion of the CKD data formatted record into a record locator table.
