Just trying to create a New Availability Group for AlwaysOn , I see the database is listed, in the status it says: "Full backup is Required. The database is AdventureWorks2012, i have taken a full backup, but still see the message. I did an attach using .mdf/ldf files for this db, it is full mode.
Created a test db and did a full backup, this shows up ok as "meets prerequisites". Just curious what wrong with the AdventureWorks2012 db from MS.
