Question,
I will be deploying Exchange 2010 incorporating DAG and the question I have is can I setup my DAG with only one passive copy at first then add the second copy and LAG copy at a later date? I know it’s best to have a 3 copy DAG but I do not have the resources available just yet to do the 3 copy DAG and would like some kind of failover if needed.

Yep. You can incrementally build a DAG (in fact, the process to install it is essentially this - you'll just be delaying a few of the commands until you have additional hardware).

Just bring the new servers up, make them members of the DAG in the usual way and then add the respective database copies. All fairly routine.

Also - and this is important - you have to make sure you have an even number of cluster members/witness disks. This means that if you have an odd number of servers, you will need at least one witness disk on a non-DAG-member server for the underlying Microsoft cluster service to work right. If you don't the cluster will freak out and your services will go offline.

The rule is: cluster service always needs an even number of members for voting/elections. This can consist of member servers and witness disks.

Cheers!
