Procedure for declaring DR using SRA

Hi,

When we declare DR in SRM we understand that primary storage will not replicate data to secondary storage.

Question 1:

But in a NOT DR scenario, a synchronously synchronized storage, can I use the SRM (Test) option without having to disable storage synchronization?

Question 2:

I want to simulate a DR scenario in real practice.

Knowing this is not a true DR, as I will actually simulate the production VM shutdown before declaring DR in SRM, do I have to disable or pause synchronous synchronization?

Thank you.
