    摘要: A method for transferring data over a network operating in accordance with a protocol, such as the ESCON protocol, that supports a limited logical address range includes establishing a logical path over the network from a host or other device to a second device, such as a storage system, using path logical addresses within the given logical address range. A virtual path is created over the logical path to carry the data from the source to the target, wherein the target logical subsystem has a subsystem logical address which is outside the given logical address range.

    摘要: An apparatus, system, and method are disclosed for updating software components while preserving data associated with the software and optionally converting the data to a new format. Persistent memory is used to preserve data structures associated with software components during the software update process, which may be accomplished by save and restore functions intrinsic to the software component being updated. The present invention includes, in one embodiment, a persistent data registry used to register each data structure saved in persistent memory during a software update. A data structure information record may be used to register each data structure in the persistent data registry. The present invention incorporates individual conversion of each data structure to facilitate adding, deleting, or modifying data structures during the software update process to accommodate the requirements of the updated software.

    摘要: A storage control unit detects a change in a configuration of a plurality of logical subsystems included in the storage control unit. The storage control unit sends a notification, wherein the notification indicates the change in the configuration of the plurality of logical subsystems. The storage control unit receives data transfer requests directed at available logical subsystems in the storage control unit, wherein the available logical subsystems are determined based on the configuration of the plurality of logical subsystems.
