Introduction:
High Availability (active-active) is implemented on an Automic Workload Automation (AWA) environment, where the Automation Engine (AE) is installed on two servers.  

A test is conducted to observe the active-active functionality, which involves rebooting the Server1 while services are up and running on Server1 & Server2.

The Service Manager Dialog (SMD) shows that the Server1 services goes down and the Server2 services stays up.
Question:
Is it the expected behavior that the AWI session gets disconnected during the fail over?

 
Answer:
Yes, this behavior is by design.  This is because most likely, the user is connected to the CP that is located in Server1.

To verify, go to the Administration tab > Connections:

AWI Administration connections

The user will just need to do a quick re-login, which will connect them to the CP that's located on the secondary server.
Additional Information:
There is no negative impact on the AE because the 2nd server it fails over to is already connected.  This can be verified by going to the Administration tab > Automation Engine Management.  Both Server1 and Server2 are listed.
