In December 2020 IBM GA'd a new version of IBM Copy Services Manager
Copy Services Manager 6.2.11 Download
Traditionally, CSM has not assimilated FlashCopy relationships. The reason for this is that it becomes difficult for CSM to validate that all volumes in the session were flashed consistently at the same time. In CSM 6.2.9 though we added a Discover command on FlashCopy sessions for DS8000 relationships. This Discover command queries the hardware and assimilates any existing relationships without having to reestablish the relationships. In CSM 6.2.11 the Discover command will now be available for Spectrum Virtualize storage as well. As with DS8000, customer should be very careful in using the Discover command and only use it for sessions where they know the relationships being assimilated are in fact consistent. RFE 144783
