In Sept 2020 IBM GA'd a new version of IBM Copy Services Manager
Copy Services Manager 6.2.10 Download
There is a property that can be set that telld CSM to issue an establish for the relationships with the No Copy option to the hardware. The No Copy option tells the hardware that the source and target are exactly the same, so that when the establish is done, there is no initial copy between the volumes and the pairs immediately go into a Prepared state. This property is not documented but can be provided for customers through the guidance of support or lab services. The property is specific to a session and role pair. In a previous release, CSM added a warning prompt so that when customers issued a start command they could see that the property was set and that the No Copy would be issued to the hardware. The warning prompt appeared after the initial start warning prompt or selection of the specific start command for multi-target sessions. This helped prevent customers from accidentally leaving the property set on subsequent starts. While the warning prompt placement prevented accidentally issuing No Copy on subsequent starts, there was no way for a customer expecting to use the No Copy to validate that they set the property correctly because it came AFTER the initial start warning prompt. In CSM 6.2.10, the warning prompt will now be the first prompt seen, helping customers ensure that they set the property correctly. In addition, a warning prompt will occur for every role pair in the session found to have the property set. This helps ensure that not only the property is set but that it's set on the correct role pair. Note though, a different warning prompt will appear for each role pair regardless of whether the role pair is a participating role pair, or if it will be affected by the command issued.
