## ActiveDR failover testing for SQL Server Failover Cluster Instance
5+
##
6+
## This demo script runs through two scenarios: -
7+
## 1. Failover of clustered SQL Server role to node on same array
8+
## 2. Failover of clustered SQL Server role to node on remote array
9+
##
10+
## The second test involves the following steps: -
11+
###### Stop clustered SQL Server role in FCI
12+
###### Demote source pod
13+
###### Promote target pod
14+
###### Move clustered role to node on target array
15+
###### Start up clustered SQL Server role

# SQL Server Failover Cluster Instance and ActiveDR
4+
5+
**Files:**
6+
- ActiveDR-FCI-Testing.ps1
7+
8+
9+
**Scenario:**
10+
11+
Testing failover of a 4 node SQL Server Failover Clustered Instance with nodes hosted on two separate FlashArrays.
12+
Failover between nodes on the same cluster will provide high availabiliy and failover between nodes on separate arrays provides disaster recovery.
13+
14+
This demo script runs through two scenarios: -
15+
1. Failover of the failover cluster instance between nodes on the same array (no ActiveDR involvement)
16+
2. Failover of the cluster instance between nodes on separate arrays (requiring ActiveDR involvement)
17+
18+
**Prerequisites:**
19+
1. Windows Cluster needs to be created, with four nodes...two on different FlashArrays
20+
2. ActiveDR pod needs to be configured to replicate between the arrays
21+
3. Volumes of the cluster hosting SQL Server databases (User and System) need to be added to the pod
22+
23+
24+
**Recording**
25+
A recording of this demo is available here: -
26+

27+
28+
29+
These scripts are meant to be run in chunks. Each Part represents an independent workflow in the greater context of a DR manual failover and manual failback. DO NOT run everything at once!
30+
31+
These examples are provided **AS-IS** and meant to be a building block examples to be adapted to fit an individual organization's infrastructure.
