# ActiveDR Failover Testing for SQL Server Failover Cluster Instance
3+
#
4+
# Scenario:
5+
# This demo script runs through two scenarios:
6+
# 1. Failover of a clustered SQL Server role to a node on the same storage array
7+
# 2. Failover of a clustered SQL Server role to a node on a remote storage array
8+
#
9+
# The remote array failover involves the following steps:
10+
# - Stop the clustered SQL Server role in the FCI
11+
# - Demote the source pod
12+
# - Promote the target pod
13+
# - Move the clustered role to a node on the target array
14+
# - Start the clustered SQL Server role
15+
#
16+
# Disclaimer:
17+
# This example script is provided AS-IS and meant to be a building block to be adapted to fit an individual
18+
# organization's infrastructure.
