What will happen when a node fail and fall over to another node ?  Any further example / guideline to show this ? How can I be notified in case there is a node failover ?

Great thanks

When node fail, All the databases will mount on another node. if you have even number of node it will contact the FSW for the voting. If there is Odd number of mailbox servers it will not use the FSW.

If you have site-Resilience scenario, you should do Data center fail over manually.

To get notification, you should use some scripts. Please refer below url

Creating a DAG require some planning. There are lot of articles you can find how to setup. However, I suggest you to focus on Hardware part first. Like Server configuration, NIC configuration (one for MAPI and another one for dag replication), Disk configuration SAN is best.

Document everything first and then work on creating DAG. As I said planning is very important. Here an article to start.
