Creating a failover clustering means you have at least two servers connected to a shared storage.
- Windows Server 2008/R2: Failover Clustering feature is available with Windows Server 2008/R2 Enterprise/Data Center editions. You don't have this feature with the Standard edition of Windows Server 2008/R2.
- Domain role: All servers in the cluster must be in the same Active Directory domain.
- DNS: The servers in the cluster must be using Domain Name System (DNS) for name resolution.
- Account for administering the cluster : When you create a cluster or add servers to it, you must be logged on to the domain with an account that has administrator rights on all servers in that cluster ( if the account is not a Domain Admins account, the account must be given the Create Computer Objects and Read All Properties permissions in the domain ).
- Servers : Two identical servers in brand, model and configurations.
- Device Controllers ( HBA ): i/SCSI or Fiber , both also to be the identical.
- Storage : You must use shared storage that is compatible with Windows Server 2008 R2.
Now that you know the requirement for Failover Clustering, lets start:
- To install Failover feature, open Server Manager, click on Start > Administrative Tools > Server Manager
- Expand Features, and then click on Add Feature.
The list of available features will be listed, select the Failover Clustering and click on Next
Click Install - The Failover Clustering feature will be installed. Click Close
- Again on Server B, we will need to install Failover Clustering feature as well, so click on Start > All Programs > Administrative Tools >Server Manager
Click on Features and then click on Add Features - Choose the Failover Clustering feature and click Next
- Confirm installing Failover Clustering by clicking on Install
Close the Add Features Wizard once installation is completed.
To open Failover Clustering, click on Start > Administrative Tools > Failover Cluster Manager
>> This needs to be done on a single server only <<
- The first step in creating a successful failover clustering, is by validating the existing systems and shared storage. This is done by the optionValidate a Configuration
When you click on Validate a Configuration, you will need to browse and add the Cluster nodes, these are the servers that will be part of the cluster, then click Next
Choose to Run all tests and click Next
The available tests will be displayed in the confirmation window, click Next to begin validating your cluster
Review the validation report, as your configuration might have few issues with it and needs to be addresses before setting up your cluster. - Now that the configuration is validated and you are ready to setup your cluster. Click on the second option, Create a Cluster, the wizard will launch, read it and then click Next
- You need to add the names of the servers you want to have in the cluster. You can start creating your cluster with a single server and then add other nodes in the future.
Browse to your servers and then once all the servers ( nodes ) are listed, click Next - After the servers are selected, you need to type a name and IP for your Cluster
- On the Confirmation window, review your settings. The following will be displayed in this window: cluster name and IP address, selected servers name. If all info is proper, then click Next. Else click Previous and correct which setting needs to be adjusted.
After you click Next, creating the cluster will begin. - The summary windows will be displayed after a successful setup of the cluster.
- Open Failover Cluster Manager and you will see your nodes and setting inside the MMC. Here you can configure your cluster, add new nodes, remove nodes, add more disk storage and so on.
In this article, I have created a two node cluster using Failover Clustering feature which is available with Windows Server 2008 R2 Enterprise and Data Center editions.

Here you can see how to setup Microsoft Windows 2008 R2 failover cluster in VMware Workstation.This article contains step by step method on Microsoft windows 2008 R2 failover cluster with freenas iscsi disks in VMware workstation just on your computer. if you search on internet about setting up Windows 2008 R2 cluster in any desktop virtualization software, you can’t find it in one place.
Installation and setup procedure for MS windows 2003 cluster and earlier versions are available on internet, but not Windows 2008 or R2 failover cluster. Everybody including me stuck in one place while setting up Windows 2008 or R2 cluster in Virtualization environment, which is Cluster disk validation. This is the main issue on MS windows 2008 R2 cluster in VMware workstation or Sun virtual box desktop virtualization software.
Windows 2008 and R2 failover clusters require SCSI-3 persistent reservation target disks as their cluster disks. Now question is how to setup SCSI-3 persistent reservation cluster disks in VMware workstation? I already wrote an article on setting up SCSI-3 persistent reservation cluster iSCSI disks in VMware workstation using FreeNAS. Before continue reading this post, please read my previous article and create cluster disks in your VMware workstation according to cluster need.
Let’s start the installation and setup of Windows 2008 or R2 Failover cluster in desktop virtualization software VMware workstation.
Required Software
a) VMware workstation
b) Windows 2008 or R2 Operating System
c) FreeNAS
Prerequisites setup
a) Installation of Windows 2008 or R2 Operating System in VMware Workstation ( Three Windows 2008 R2 Server virtual machines required. One as domain controller and other twos as cluster nodes)
b) Setup domain on one server and join other two servers with domain. Use domain administrator login for servers. ( in this example, domain name is sysprobs.net and cluster server names are vm-clus1 and vm-clus2)
c) Install failover cluster feature in two windows 2008 or R2 servers you are going to setup failover cluster in VMware workstation.
d) Install second network card in both cluster servers. Give two separate IP addresses, so both servers can communicate through this network also. This network will be used as ‘heart beat’ network for both servers. Make sure, this network name is identical in both servers. (in this example, heart beat network named as ‘ internal’ on both servers)
e) Create cluster disks in your FreeNAS virtual machine. Read my previous post on creating SCSI-3 persistent reservation target iSCSI disks in FreeNAS.
( in this example,
Qurom disk – 512MB,
Storage disk1- 2GB,
Storage disk 2- 2GB,
Storage disk 3 – 2GB,
and Backup disk 4GB)
Start Setup – Windows 2008 R2 Failover Cluster in VMware workstation
1) In first cluster server, Open iSCSI initiator under administrative tools. Click Yes, if it asks to start the iSCSI service.
2) Give FreeNAS IP address in Target and press Quick Connect.
It will detect your target disks. Pres Done.
3) You can see each disk shows Inactive status. Click on each target and press connect until all targets’ status show as connected.
4) Go to Volumes and Devices tab, and press Auto Configure button. Your all targets will come as disks under this tab.
5) All iSCSI disks will be listed under disk management is server manager. Right Click on each disk, make it online and Initialize the disks.
6) Create simple volumes by right clicking and selecting on each unallocated space. Format the drives and give name for each disk.
7) After all disks formatted and named successfully, right click on each drives and make them offline again.
see below.
8) Now go to second cluster server. Start iSCSI services and detect all target disks as you did in first server. But you do not need to format and name the disks in second server. Here also, make sure all disks detected and made offline in disk management.
9) Now, start failover cluster manager in features under server manager. Before create cluster, better to validate cluster configuration, especially the tricky part SCSI-3 persistent reservation iSCSI disks which we configured in FreeNAS.
10) Click on Validate a configuration under management.
11) Click Next and browse the cluster servers from active directory or enter full name of servers.
12) If you are confident, run all tests or run part by part. Wait for result…. Here we go.
My all tests passed, and ready for create windows 2008 or R2 cluster in VMware workstation.
13) Final validate configure result shown below.
Now, create cluster and start making. Other steps are very easy. I don’t need to explain deeply, because cluster validation is very important.
14) I gave cluster name ‘ vm-cluster’ and separate IP address 192.5.2.250.
15) That’s it. We have successfully created windows 2008 or R2 failover cluster in vmware workstation using FreeNAS.
Unfortunately, it took one of my 2GB disk as quorum disk. But no problem, we can change it later. That option is available in windows 2008 R2 cluster.
Obviously, server performance will be poor, since we run 3 windows 2008 R2 servers and FreeNAS operating systems inside VMware workstation. This is just for testing and learning purpose only.

Oracle has announced support for running MySQL on Windows Server Failover Clustering (WSFC); with so many people developing and deploying MySQL on Windows, this offers a great option to add High Availability to MySQL deployments if you don’t want to go as far as deploying MySQL Cluster.
This post will give a brief overview of how to set things up but for all of the gory details a new white paper MySQL with Windows Server 2008 R2 Failover Clustering is available – please give me any feedback. I will also be presenting on this at a free webinar on Thursday 15th September (please register in advance) as well at an Oracle OpenWorld session in San Francisco on Tuesday 4th October (Tuesday, 01:15 PM, Marriott Marquis – Golden Gate C2) – a good opportunity to get more details and get your questions answered.
It sometimes surprises people just how much MySQL is used on Windows, here are a few of the reasons:
- Lower TCO
- 90% savings over Microsoft SQL Server
- If your a little skeptical about this then try it out for yourself with the MySQL TCO Savings Calculator
- Broad platform support
- No lock-in
- Windows, Linux, MacOS, Solaris
- Ease of use and administration
- < 5 mins to download, install & configure
- MySQL Enterprise Monitor & MySQL WorkBench
- Reliability
- 24×7 Uptime
- Field Proven
- Performance and scalability
- MySQL 5.5 delivered over 500% performance boost on Windows.
- Integration into Windows environment
- ADO.NET, ODBC & Microsoft Access Integration
- And now, support for Windows Server Failover Clustering!
Solution Overview
MySQL with Windows Failover Clustering requires at least 2 servers within the cluster together with some shared storage (for example FCAL SAN or iSCSI disks). For redundancy, 2 LANs should be used for the cluster to avoid a single point of failure and typically one would be reserved for the heartbeats between the cluster nodes.
The MySQL binaries and data files are stored in the shared storage and Windows Failover Clustering ensures that at most one of the cluster nodes will access those files at any point in time (hence avoiding file corruptions).
Clients connect to the MySQL service through a Virtual IP Address (VIP) and so in the event of failover they experience a brief loss of connection but otherwise do not need to be aware that the failover has happened other than to handle the failure of any in-flight transactions.
Target Configuration
This post will briefly step through how to set up and use a cluster and this diagrams shows how this is mapped onto physical hardware and network addresses for the lab used later in this post. In this case, iSCSI is used for the shared storage. Note that ideally there would be an extra subnet for the heartbeat connection between ws1 and ws3.
This is only intended to be an overview and the steps have been simplified refer to the white paper for more details on the steps.
Prerequisites
- MySQL 5.5 & InnoDB must be used for the database (note that MyISAM is not crash-safe and so failover may result in a corrupt database)
- Windows Server 2008 R2
- Redundant network connections between nodes and storage
- WSFC cluster validation must pass
- iSCSI or FCAL SAN should be used for the shared storage
Step 1 Configure iSCSI in software (optional)
This post does not attempt to describe how to configure a highly available, secure and performant SAN but in order to implement the subsequent steps shared storage is required and so in this step we look at one way of using software to provide iSCSI targets without any iSCSI/SAN hardware (just using the server’s internal disk). This is a reasonable option to experiment with but probably not what you’d want to deploy with for a HA application. If you already have shared storage set up then you can skip this step and use that instead.
As part of this process you’ll create at least two virtual disks within the iSCSI target; one for the quorum file and one for the MySQL binaries and data files. The quorum file is used by Windows Failover Clustering to avoid “split-brain” behaviour.
Step 2. Ensure Windows Failover Clustering is enabled
To confirm that Windows Failover Clustering is installed on ws1 and ws3, open the “Features” branch in the Server Manager tool and check if “Failover Cluster Manager” is present.
If Failover Clustering is not installed then it is very simple to add it. Select “Features” within the Service Manager and then click on “Add Features” and then select “Failover Clustering” and then “Next”.
Step 3. Install MySQL as a service on both servers
If MySQL is already installed as a service on both ws1 and ws3 then this step can be skipped.
The installation is very straight-forward using the MySQL Windows Installer and selecting the default options is fine.
Within the MySQL installation wizard, sticking with the defaults is fine for this exercise. When you reach the configuration step, check “Create Windows Service”.
The installation and configuration must be performed on both ws1 and ws2, if necessary.
Step 4. Migrate MySQL binaries & data to shared storage
If the MySQL Service is running on either ws1 or ws3 then stop it – open the Task Manager using ctrl-shift-escape, select the “Services” tab and then right-click on the MySQL service and choose “Stop Service”.
As the iSCSI disks were enabled on ws1 you can safely access them in order to copy across the MySQL binaries and data files to the shared disk.
Step 5. Create Windows Failover Cluster
From the Server Manager on either ws1 or ws3 navigate to “Features -> Failover Cluster Manager” and then select “Validate a Configuration”. When prompted enter ws1 as one name and then ws3 as the other.
In the “Testing Options” select “Run all tests” and continue. If the tests report any errors then these should be fixed before continuing.
Now that the system has been verified, select “Create a Cluster” and provide the same server names as used in the validation step. In this example, “MySQL” is provided as the “Cluster Name” and then the wizard goes on to create the cluster.
Step 6. Create Cluster of MySQL Servers within Windows Cluster
Adding the MySQL service to the new Cluster is very straight-forward. Right-click on “Services and applications” in the Server Manager tree and select “Configure a Service or Application…”. When requested by the subsequent wizard, select “Generic Service” from the list and then “MySQL” from the offered list of services. Our example name was “ClusteredMySQL”. Please choose an appropriate name for your cluster. The wizard will then offer the shared disk that has not already been established as the quorum disk for use with the Clustered service – make sure that it is selected.
Once the wizard finishes, it starts up the MySQL Service. Click on the “ClusteredMySQL” service branch to observe that the service is up and running. You should also make a note of the Virtual IP (VIP) assigned, in this case 192.168.2.18.
Step 7. Test the cluster
As described in Step 6, the VIP should be used to connect to the clustered MySQL service:
From there create a database and populate some data.
The MySQL service was initially created on ws1 but it can be forced to migrate to ws3 by right-clicking on the service and selecting “Move this service or application to another node”.
As the MySQL data is held in the shared storage (which has also been migrated to ws3), it is still available and can still be accessed through the existing mysql client which is connected to the VIP:
Note the error shown above – the mysql client loses the connection to the MySQL service as part of the migration and so it automatically reconnects and complete the query. Any application using MySQL with Windows Failover Cluster should also expect to have to cope with these “glitches” in the connection.
Conclusion
More users develop and deploy and MySQL on Windows than any other single platform. Enhancements in MySQL 5.5 increased performance by over 5x compared to previous MySQL releases. With certification for Windows Server Failover Clustering, MySQL can now be deployed to support business critical workloads demanding high availability, enabling organizations to better meet demanding service levels while also reducing TCO and eliminating single vendor lock-in.

This topic shows how to create a failover cluster by using either the Failover Cluster Manager snap-in or Windows PowerShell. The topic covers a typical deployment, where computer objects for the cluster and its associated clustered roles are created in Active Directory Domain Services (AD DS). If you're deploying a Storage Spaces Direct cluster, instead see Deploy Storage Spaces Direct.
You can also deploy an Active Directory-detached cluster. This deployment method enables you to create a failover cluster without permissions to create computer objects in AD DS or the need to request that computer objects are prestaged in AD DS. This option is only available through Windows PowerShell, and is only recommended for specific scenarios. For more information, see Deploy an Active Directory-Detached Cluster.
Checklist: Create a failover cluster
Status | Task | Reference |
---|---|---|
☐ | Verify the prerequisites | Verify the prerequisites |
☐ | Install the Failover Clustering feature on every server that you want to add as a cluster node | Install the Failover Clustering feature |
☐ | Run the Cluster Validation Wizard to validate the configuration | Validate the configuration |
☐ | Run the Create Cluster Wizard to create the failover cluster | Create the failover cluster |
☐ | Create clustered roles to host cluster workloads | Create clustered roles |
Verify the prerequisites
Before you begin, verify the following prerequisites:
- Make sure that all servers that you want to add as cluster nodes are running the same version of Windows Server.
- Review the hardware requirements to make sure that your configuration is supported. For more information, see Failover Clustering Hardware Requirements and Storage Options. If you're creating a Storage Spaces Direct cluster, see Storage Spaces Direct hardware requirements.
- To add clustered storage during cluster creation, make sure that all servers can access the storage. (You can also add clustered storage after you create the cluster.)
- Make sure that all servers that you want to add as cluster nodes are joined to the same Active Directory domain.
- (Optional) Create an organizational unit (OU) and move the computer accounts for the servers that you want to add as cluster nodes into the OU. As a best practice, we recommend that you place failover clusters in their own OU in AD DS. This can help you better control which Group Policy settings or security template settings affect the cluster nodes. By isolating clusters in their own OU, it also helps prevent against accidental deletion of cluster computer objects.
Additionally, verify the following account requirements:
- Make sure that the account you want to use to create the cluster is a domain user who has administrator rights on all servers that you want to add as cluster nodes.
- Make sure that either of the following is true:
- The user who creates the cluster has the Create Computer objects permission to the OU or the container where the servers that will form the cluster reside.
- If the user does not have the Create Computer objects permission, ask a domain administrator to prestage a cluster computer object for the cluster. For more information, see Prestage Cluster Computer Objects in Active Directory Domain Services.
Note
This requirement does not apply if you want to create an Active Directory-detached cluster in Windows Server 2012 R2. For more information, see Deploy an Active Directory-Detached Cluster.
Install the Failover Clustering feature
Failover Cluster Manager 2012 R2
You must install the Failover Clustering feature on every server that you want to add as a failover cluster node.
Install the Failover Clustering feature
Start Server Manager.
On the Manage menu, select Add Roles and Features.
On the Before you begin page, select Next.
On the Select installation type page, select Role-based or feature-based installation, and then select Next.
On the Select destination server page, select the server where you want to install the feature, and then select Next.
On the Select server roles page, select Next.
On the Select features page, select the Failover Clustering check box.
To install the failover cluster management tools, select Add Features, and then select Next.
On the Confirm installation selections page, select Install.
A server restart is not required for the Failover Clustering feature.When the installation is completed, select Close.
Repeat this procedure on every server that you want to add as a failover cluster node.
Note
After you install the Failover Clustering feature, we recommend that you apply the latest updates from Windows Update. Also, for a Windows Server 2012-based failover cluster, review the Recommended hotfixes and updates for Windows Server 2012-based failover clusters Microsoft Support article and install any updates that apply.
Validate the configuration
Before you create the failover cluster, we strongly recommend that you validate the configuration to make sure that the hardware and hardware settings are compatible with failover clustering. Microsoft supports a cluster solution only if the complete configuration passes all validation tests and if all hardware is certified for the version of Windows Server that the cluster nodes are running.
Note
You must have at least two nodes to run all tests. If you have only one node, many of the critical storage tests do not run.
Run cluster validation tests
On a computer that has the Failover Cluster Management Tools installed from the Remote Server Administration Tools, or on a server where you installed the Failover Clustering feature, start Failover Cluster Manager. To do this on a server, start Server Manager, and then on the Tools menu, select Failover Cluster Manager.
In the Failover Cluster Manager pane, under Management, select Validate Configuration.
On the Before You Begin page, select Next.
On the Select Servers or a Cluster page, in the Enter name box, enter the NetBIOS name or the fully qualified domain name of a server that you plan to add as a failover cluster node, and then select Add. Repeat this step for each server that you want to add. To add multiple servers at the same time, separate the names by a comma or by a semicolon. For example, enter the names in the format
server1.contoso.com, server2.contoso.com
. When you are finished, select Next.On the Testing Options page, select Run all tests (recommended), and then select Next.
On the Confirmation page, select Next.
The Validating page displays the status of the running tests.
On the Summary page, do either of the following:
If the results indicate that the tests completed successfully and the configuration is suited for clustering, and you want to create the cluster immediately, make sure that the Create the cluster now using the validated nodes check box is selected, and then select Finish. Then, continue to step 4 of the Create the failover cluster procedure.
If the results indicate that there were warnings or failures, select View Report to view the details and determine which issues must be corrected. Realize that a warning for a particular validation test indicates that this aspect of the failover cluster can be supported, but might not meet the recommended best practices.
Note
If you receive a warning for the Validate Storage Spaces Persistent Reservation test, see the blog post Windows Failover Cluster validation warning indicates your disks don't support the persistent reservations for Storage Spaces for more information.
For more information about hardware validation tests, see Validate Hardware for a Failover Cluster.
Create the failover cluster
To complete this step, make sure that the user account that you log on as meets the requirements that are outlined in the Verify the prerequisites section of this topic.
Start Server Manager.
On the Tools menu, select Failover Cluster Manager.
In the Failover Cluster Manager pane, under Management, select Create Cluster.

For example, go to the ChemOffice2005 program group and launch ChemDraw.
On the Before You Begin page, select Next.
If the Select Servers page appears, in the Enter name box, enter the NetBIOS name or the fully qualified domain name of a server that you plan to add as a failover cluster node, and then select Add. Repeat this step for each server that you want to add. To add multiple servers at the same time, separate the names by a comma or a semicolon. For example, enter the names in the format server1.contoso.com; server2.contoso.com. When you are finished, select Next.
Note
If you chose to create the cluster immediately after running validation in the configuration validating procedure, you will not see the Select Servers page. The nodes that were validated are automatically added to the Create Cluster Wizard so that you do not have to enter them again.
If you skipped validation earlier, the Validation Warning page appears. We strongly recommend that you run cluster validation. Only clusters that pass all validation tests are supported by Microsoft. To run the validation tests, select Yes, and then select Next. Complete the Validate a Configuration Wizard as described in Validate the configuration.
On the Access Point for Administering the Cluster page, do the following:
In the Cluster Name box, enter the name that you want to use to administer the cluster. Before you do, review the following information:
- During cluster creation, this name is registered as the cluster computer object (also known as the cluster name object or CNO) in AD DS. If you specify a NetBIOS name for the cluster, the CNO is created in the same location where the computer objects for the cluster nodes reside. This can be either the default Computers container or an OU.
- To specify a different location for the CNO, you can enter the distinguished name of an OU in the Cluster Name box. For example: CN=ClusterName, OU=Clusters, DC=Contoso, DC=com.
- If a domain administrator has prestaged the CNO in a different OU than where the cluster nodes reside, specify the distinguished name that the domain administrator provides.
If the server does not have a network adapter that is configured to use DHCP, you must configure one or more static IP addresses for the failover cluster. Select the check box next to each network that you want to use for cluster management. Select the Address field next to a selected network, and then enter the IP address that you want to assign to the cluster. This IP address (or addresses) will be associated with the cluster name in Domain Name System (DNS).
When you are finished, select Next.
On the Confirmation page, review the settings. By default, the Add all eligible storage to the cluster check box is selected. Clear this check box if you want to do either of the following:
- You want to configure storage later.
- You plan to create clustered storage spaces through Failover Cluster Manager or through the Failover Clustering Windows PowerShell cmdlets, and have not yet created storage spaces in File and Storage Services. For more information, see Deploy Clustered Storage Spaces.
Select Next to create the failover cluster.
On the Summary page, confirm that the failover cluster was successfully created. If there were any warnings or errors, view the summary output or select View Report to view the full report. Select Finish.
To confirm that the cluster was created, verify that the cluster name is listed under Failover Cluster Manager in the navigation tree. You can expand the cluster name, and then select items under Nodes, Storage or Networks to view the associated resources.
Realize that it may take some time for the cluster name to successfully replicate in DNS. After successful DNS registration and replication, if you select All Servers in Server Manager, the cluster name should be listed as a server with a Manageability status of Online.
After the cluster is created, you can do things such as verify cluster quorum configuration, and optionally, create Cluster Shared Volumes (CSV). For more information, see Understanding Quorum in Storage Spaces Direct and Use Cluster Shared Volumes in a failover cluster.
Create clustered roles
After you create the failover cluster, you can create clustered roles to host cluster workloads.
Note
For clustered roles that require a client access point, a virtual computer object (VCO) is created in AD DS. By default, all VCOs for the cluster are created in the same container or OU as the CNO. Realize that after you create a cluster, you can move the CNO to any OU.
Here's how to create a clustered role:
Use Server Manager or Windows PowerShell to install the role or feature that is required for a clustered role on each failover cluster node. For example, if you want to create a clustered file server, install the File Server role on all cluster nodes.
The following table shows the clustered roles that you can configure in the High Availability Wizard and the associated server role or feature that you must install as a prerequisite.
Clustered Role Role or Feature Prerequisite Namespace Server Namespaces (part of File Server role) DFS Namespace Server DHCP Server role Distributed Transaction Coordinator (DTC) None File Server File Server role Generic Application Not applicable Generic Script Not applicable Generic Service Not applicable Hyper-V Replica Broker Hyper-V role iSCSI Target Server iSCSI Target Server (part of File Server role) iSNS Server iSNS Server Service feature Message Queuing Message Queuing Services feature Other Server None Virtual Machine Hyper-V role WINS Server WINS Server feature In Failover Cluster Manager, expand the cluster name, right-click Roles, and then select Configure Role.
Follow the steps in the High Availability Wizard to create the clustered role.
To verify that the clustered role was created, in the Roles pane, make sure that the role has a status of Running. The Roles pane also indicates the owner node. To test failover, right-click the role, point to Move, and then select Select Node. In the Move Clustered Role dialog box, select the desired cluster node, and then select OK. In the Owner Node column, verify that the owner node changed.
Create a failover cluster by using Windows PowerShell
The following Windows PowerShell cmdlets perform the same functions as the preceding procedures in this topic. Enter each cmdlet on a single line, even though they may appear word-wrapped across several lines because of formatting constraints.
Note
You must use Windows PowerShell to create an Active Directory-detached cluster in Windows Server 2012 R2. For information about the syntax, see Deploy an Active Directory-Detached Cluster.
The following example installs the Failover Clustering feature.
The following example runs all cluster validation tests on computers that are named Server1 and Server2.
Note
The Test-Cluster cmdlet outputs the results to a log file in the current working directory. For example: C:Users<username>AppDataLocalTemp.
The following example creates a failover cluster that is named MyCluster with nodes Server1 and Server2, assigns the static IP address 192.168.1.12, and adds all eligible storage to the failover cluster.
The following example creates the same failover cluster as in the previous example, but it does not add eligible storage to the failover cluster.
The following example creates a cluster that is named MyCluster in the Cluster OU of the domain Contoso.com.
For examples of how to add clustered roles, see topics such as Add-ClusterFileServerRole and Add-ClusterGenericApplicationRole.

-->To install a SQL Server failover cluster, you must create and configure a failover cluster instance by running SQL Server Setup.
Installing a Failover Cluster
To install a failover cluster, you must use a domain account with local administrator rights, permission to log on as a service, and to act as part of the operating system on all nodes in the failover cluster. To install a failover cluster by using the SQL Server Setup program, follow these steps:
To install, configure, and maintain a SQL Server failover cluster, use SQL Server Setup.
Identify the information you need to create your failover cluster instance (for example, cluster disk resource, IP addresses, and network name) and the nodes available for failover. For more information:
The configuration steps must take place before you run the SQL Server Setup program; use the Windows Cluster Administrator to carry them out. You must have one WSFC group for each failover cluster instance you want to configure.
You must ensure that your system meets minimum requirements. For more information on specific requirements for a SQL Server failover cluster, see Before Installing Failover Clustering.
Add or remove nodes from a failover cluster configuration without affecting the other cluster nodes. For more information, see Add or Remove Nodes in a SQL Server Failover Cluster (Setup).
- All nodes in a failover cluster must be of the same platform, either 32-bit or 64-bit, and must run the same operating system edition and version. Also, 64-bit SQL Server editions must be installed on 64-bit hardware running the 64-bit versions of Windows operating systems. There is no WOW64 support for failover clustering in this release.
Specify multiple IP addresses for each failover cluster instance. You can specify mutiple IP addresses for each subnet. If the mutiple IP addresses are on the same subnet, SQL Server Setup sets the dependency to AND. If you are clustering nodes across multiple subnets, SQL Server Setup sets the dependency to OR.
SQL Server failover cluster instance (FCI) requires the cluster nodes to be domain joined. The following configurations are not supported:
- SQL FCI on workgroup clusters.
- SQL FCI on Multi-Domain cluster.

Option 1: Integrated installation with Add Node
SQL Server integrated failover cluster installation consists of two steps:
Create and configure a single-node SQL Server failover cluster instance. At the completion of a successful configuration of the node, you have a fully functional failover cluster instance. At this time it does not have high-availability because there is only one node in the failover cluster.
On each node to be added to the SQL Server failover cluster, run Setup with Add Node functionality to add that node.
Option 2: Advanced/Enterprise installation
SQL Server Advanced/Enterprise failover cluster installation consists of two steps:
On each node that will be part of the SQL Server failover cluster, run Setup with Prepare Failover Cluster functionality. This step prepares the nodes ready to be clustered, but there is no operational SQL Server instance at the end of this step.
After the nodes are prepared for clustering, run Setup on the node that owns the shared disk with the Complete Failover Cluster functionality. This step configures and completes the failover cluster instance. At the end of this step, you will have an operational SQL Server failover cluster instance.
Note
Either installation option allows for multi-node SQL Server failover cluster installation. Add Node can be used to add additional nodes for either option after a SQL Server failover cluster has been created.
Important
The operating system drive letter for SQL Server install locations must match on all the nodes added to the SQL Server failover cluster.

IP Address Configuration During Setup
SQL Server Setup lets you set or change the IP resource dependency settings during the following actions:
Integrated Install - Create a New SQL Server Failover Cluster (Setup)
CompleteFailoverCluster (Advanced Install) - Create a New SQL Server Failover Cluster (Setup)
Add Node - Add or Remove Nodes in a SQL Server Failover Cluster (Setup)
Remove Node - Add or Remove Nodes in a SQL Server Failover Cluster (Setup)
Note IPV6 IP addresses are supported. If you configure both IPV4 and IPV6 there are treated like different subnets, and IPV6 is expected to come online first.
SQL Server Multi-Subnet Failover Cluster
You can set OR dependencies when the nodes on the cluster are on different subnets. However, each node in the SQL Server multi-subnet failover cluster must be a possible owner of at least one of IP address specified.
