Abstract
This invention enables managing data consistency between different data volumes by managing I/O traffic in a data storage environment. A methodology for managing data consistency, in accordance with the principles of the invention, comprises the steps of arresting processing of I/O traffic during an administrative operation, queuing any I/O that follow the arresting step in a queuing data structure and processing each queued I/O until the I/O processing is completed. Certain implementations of the invention include a system, a computer program product, or an apparatus, wherein each embodiment is configured for carrying out the steps involved in the methodology.
