 ## ActiveDR failover testing for SQL Server Failover Cluster Instance
 ## 
-## Script actions: -
-### Perform failover of clustered SQL Server role to node on same array
-### Then perform failover of clustered SQL Server role to node on remote array: -
+## This demo script runs through two scenarios: -
+## 1. Failover of clustered SQL Server role to node on same array
+## 2. Failover of clustered SQL Server role to node on remote array
+##
+## The second test involves the following steps: -
 ###### Stop clustered SQL Server role in FCI
 ###### Demote source pod
 ###### Promote target pod

 **Scenario:**
 
-Testing failover of a SQL Server Failover Clustered Instance with nodes hosted on two separate FlashArrays.
+Testing failover of a 4 node SQL Server Failover Clustered Instance with nodes hosted on two separate FlashArrays.
+Failover between nodes on the same cluster will provide high availabiliy and failover between nodes on separate arrays provides disaster recovery.
 
+This demo script runs through two scenarios: -
+1. Failover of the failover cluster instance between nodes on the same array (no ActiveDR involvement)
+2. Failover of the cluster instance between nodes on separate arrays (requiring ActiveDR involvement)
 
 **Prerequisites:**
 1. Windows Cluster needs to be created, with four nodes...two on different FlashArrays
