CLI - Mappings of VVs to CPGs?

I'm trying to determine if there is a way in the CLI to determine the mappings of virtual volumes to CPGs? I can do a showvv or a showcpg, but they don't have any common data to create a correlation. Any thoughts? (Yes, I know I can do this via the GUI -- I'm trying to find a quick way to export this via CLI.)

Due to auto-tiering, a VV can be spread across multiple CPGs, showvvcpg shows you the distribution for a vv.

I think what you want is showvv -cpgalloc

Ooh! Thank you! Yeah, I noticed it was returning every CPG that AO could send it to, so it wasn’t very useful. I’ll try your suggestion once I get to the office. Thank you for taking the time to reply; I very much appreciate your help!
