There is only one clause, so it is automatically the main clause. "Rafael" is a noun of address, not a clause. If you has said, "I asked Rafael whether he had seen my textbook," then "I asked Rafael" would be the main clause.
The main clause in the sentence "Have you seen my textbook, Rafael?" is "Have you seen my textbook." This is an independent clause that can stand alone as a complete thought, while "Rafael" serves as an address, providing additional context.
