If it's coded as LH - you will not be able to gain Etihad miles - but only Lufthansa miles, as the ticket has been issued on Lufthansa's ticket stock on their codeshare flight number.
If it's coded as EY xxx - you can get miles - I'd fill in the claim miles form on Etihad Guest's website - https://www.etihadguest.com/en/my-ac...av=Claim_Miles
You can get EY-marketed sectors on LH connecting to EY-operated sectors through Germany - or stand-alone LH flights via their new ticketing website that nows shows prime flight numbers when no codeshares are available albeit at a slightly higher price.
