Application: Management method (Patent ID: US20240103983A1)

The patent filed by Hitachi Ltd. describes a management method that involves accessing API interfaces to collect data related to primary volumes, remote copy volumes, and shared upload volumes. The method includes generating order topology for these volumes, calculating sets of volumes storing data to be deleted, specifying relationships between these sets in the order topology, and identifying primary volumes at different levels in the order topology based on these calculations. The method aims to efficiently manage the relation among primary volumes, remote copy volumes, and shared upload volumes in a data storage system.

Additionally, the patent claims include steps for user input reception to specify data to be deleted, GUI display of calculated volume sets, and details about the disposition of volumes on a public cloud. The method also involves copying primary volumes to virtual secondary volumes before transferring them to remote copy volumes or shared upload volumes. The specification steps further include identifying remote copy volumes coupled to primary volumes through secondary volumes and primary volumes at higher levels in the order topology. Overall, the method provides a systematic approach to managing data deletion and volume relationships in a storage environment, particularly in a cloud-based system.
