In this blog, I will configure iSCSI SAN which is a feature in Windows 2012, after setting up iSCSI SAN I will create a 2 Node Failover clustering in Windows 2012 accessing the shared iSCSI SAN.
Server 2012 Failover Clustering iSCSI
Environment Details.
Server2012-DC
Ethernet0 10.0.0.20
iSCSI (Server2012)
Ethernet0 10.0.0.100
Server-1 (Node1)
Ethernet0 10.0.0.20
Ethernet1 192.168.0.10
Server-1 (Node2)
Ethernet0 10.0.0.20
Ethernet1 192.168.0.20
CLUSTER IP ADDRESS – 10.0.0.110
First, we’d like to put in and Configure target iSCSI server in Windows Server 2012 (iSCSI – Server2012)

How to Add Failover Manager Feature and iSCSI virtual disk to first Node (Server-1).
1- Open Server Manage, left side select dashboard and click on ADD Roles and Features.
2- Click Next.
3- Click Role-based or feature-based installation and then click Next.
4- Select a server from the server pool and click on next.
5- Click the Application Serve role and click next.
6- Select the Failover clustering box.
7- Click Add features.
8- After enabling the failover clustering feature, click next.
9- Application Server feature, click next.
10- Click Next.
11- Click Install.
12- Successfully enable the failover cluster feature, click Close.
Adding the Virtual Disk.
13- Open Server Manager, click Tools and Click iSCSI initiator.
14- Type the IP address or Name of the Target iSCSI server (my iSCSI target server IP is 10.0.0.100) and click Quick Connect.
15- Click on all the inactive disks and click connect.
16- After all the disk is connected, click Done.
17- Click OK.
Adding Failover Manager Feature and iSCSI virtual disk to 2 Node (Server-2).
Follow all the steps (from 1 to 17) the same as 1 Node (Server-1).
18- After successfully added the disk and connected.
Initializing the Disk and Formatting
Note: If you are working on a Failover cluster the following steps need to be performed only on a Single Node of the cluster.
The following steps are performed on the 1 Node (Server-1).
19- In Server Manager click Tools and click Computer Management.
20- Click on Disk Management.
In Computer Management You will see 2 disk’s which we added using iSCSI initiator as Unknown and offline status.
21- Right-click on each disk and select Online.
22- Right-click on disk and click Initialize Disk.
23- Select both the disks and click ok.
24- Now both the Disk are online and Unallocated.
25- Right-click on the unallocated disk and select New Simple Volume.
26- Click Next.
27- Click Next.
28- Assign a drive letter and click next.
29- Type a volume label and click next.
30- Click Finish.
Follow the same steps (from 25 to 30) for the 2nd disk (QUORUM).
31- Now both the disks are online and healthy.
The next step is to log in to 2 Node (Server-2).
Open Computer Management and click Disk Management.
Note: Disks are offline and unallocated status.
32- Right-click and bring the disk online.
33- You will notice that disk are online with assigned drive letters and volume name.
34- Right-click on each disk and select offline on both the Nodes (Server-1 and Server-2)
35- Now both the disks are offline.
FAILOVER Cluster MANAGER CONFIGURATION.
I am logged in on 1 Node (Server-1) with domain Administrative rights.
36- Open Server Manager > select tools and then click Failover Cluster Manager.
37- Click Validate configuration.
38- Click Next.
39- Click the Browse button.
40- Type node names, click check names and then click ok.
41- After selecting both the servers, so click next.
42- Select Run all tests (Recommended) and then click next.
43- Click Next.
Make sure all the Failover Cluster Validation testing completes with no errors.
44- leave the Checkbox selected to create the cluster now using the validated nodes and then click Finish it will start the cluster creation wizard.
45- Click Next.
46- Click the Browse button.
47- Type server names, click check names and then click ok.
48- Type a Cluster Name and IP address and then click next.
49- Leave the Checkbox to add all storage to Cluster and then click next.
50- Default Running Process.
51- Failover cluster Successfully completed, so click Close.
Quorum Settings.
52- When creating a cluster, depending on the number of Nodes it automatically picks the correct quorum settings and then disk.
53- If you need to change settings, right-click cluster, more action select configure cluster quorum settings.
We have successfully created the Failover Cluster, let’s test the Failover.
54- Active Node (Server-1) before Failover.
55- Active Node (Server-2) after Failover.
We have successfully tested the Failover Cluster in Windows Server 2012.
