SnapVX Question Cascading Snaps

Question

Hello, We have a new VMAX3 and we are learning snapvx. Everything has been working great until we try cascading snaps. So here is the scenario. Source LUN = 2D Target1 LUN= 2F Target2 LUN = 30 We took a snap of 2D and linked that snap to 2F. All the data is there as expected Next we changed the data on 2F We then took a snap of 2F and linked to 30 however we are still getting data from 2D. All of these LUNs do sit behind a vplex however we are doing a cache-invalidate before bringing the disk online and like I said the initial snap and linking to target1 works just fine. Any thoughts would be appreciated.

We were able to resolve this issue by starting over. We must of had the LUNs in the wrong DG. We did change to SG as well.
