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 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 concurrent upgrade of a plurality of components in a storage subsystem are provided. 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.
