Later, if the consistency group has many volumes, it is possible that the unfreeze command can arrive after some volumes' timers have expired, so the consistency group does not form

Abstract

A computer-implemented method, computer program product, and system for generating a consistency group are provided. For each source volume that has an immediate virtual copy relationship with a target volume, set the source volume's indicator in the Fast Incremental Freeze (FIF) graph to true. The consistency group is generated for each source volume whose indicator is set to true in the FIF map and each associated target volume by executing an express instant virtual copy (IVC) freeze command to freeze each and executing a consistency group generation instruction to unfreeze each source volume whose indicator is set true in the FIF map.

Description

technical field [0001] Embodiments of the present invention relate to multi-volume instant virtual copy freezing. Background technique [0002] A computer system typically includes one or more host computers (“hosts”) for processing data and running applications, a direct access storage device (DASD) for storing data, and a Transport storage controller. A storage controller, also known as a control unit or a storage director, manages access to a storage space made up of hard drives, also known as direct access storage devices (DASDs). The host can send input / output (I / O) requests to the storage space through the storage controller. [0003] Some disaster recovery systems address data lost for a period of time, in which case writes to volumes in data storage may be lost. Write operations can update data, write new data, or write the same data again. To aid in recovering data writes, a copy of the data can be provided at a remote location. Such copies are also known as do...
