Step 1. Failover Cluster Deployment


To create a failover cluster, the Failover Clustering feature needs to be installed on every server that you want to add as a failover cluster node along with with an Ekran System Application Server instance.


The deployment of the failover cluster consists of the following steps:

Step 1. Install the Failover Clustering feature on every server.

Step 2. Validate the configuration on every server.

Step 3. Create the failover cluster.

 

NOTE: For more information on deploying the Failover Cluster, see the Microsoft documentation at https://docs.microsoft.com/en-us/windows-server/failover-clustering/failover-clustering-overview


Before installing the Failover Clustering feature, make sure the following account requirements are met:

• 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.

• The user who creates the cluster has the Create Computer objects permission to the organizational unit in the domain.


Step 1. To install the Failover Clustering feature, do the following:

1. Open Server Manager.

     

2. On the Manage menu, select Add Roles and Features.

     

3. On the Before you begin page, click Next.

4. On the Select installation type page, select Role-based or feature-based installation, and then click Next.

5. On the Select destination server page, select the server where you want to install the feature, and then click Next.

6. On the Select server roles page, click Next.

7. On the Select features page, select the Failover Clustering checkbox.

8. To install the failover cluster management tools, select Add Features, and then click Next.

9. On the Confirm installation selections page, click Install.

10. When the installation is completed, click Close.

NOTE: Repeat this procedure on every server that you want to add as a failover cluster node.


Step 2. To validate the configuration, do the following:

1. Open Server Manager on the server where the Failover Clustering feature was installed.

2. On the Tools menu, select Failover Cluster Manager.

    

3. In the Failover Cluster Manager window, on the Actions pane, select Validate Configuration.

    

4. On the Before You Begin page, click Next.

5. On the Select Servers or a Cluster page, in the Enter name box, enter the NetBIOS name or the fully qualified domain name of all servers that you plan to add as failover cluster nodes, and then click Next.

   

6. On the Testing Options page, select Run all tests (recommended), and then click Next.

7. On the Confirmation page, click Next.

8. The Validating page displays the status of the running tests.

9. 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, click Finish.

• If the results indicate that there were warnings or failures, select View Report to view the details and determine which issues must be corrected. It is recommended to fix any warnings detected, and necessary to fix the failures detected.

NOTE: Repeat this procedure on every server that you want to add as a failover cluster node.

 

Step 3. To create the failover cluster, do the following:

1. Open Server Manager.

2. On the Tools menu, select Failover Cluster Manager.

3. In the Failover Cluster Manager window, in the Actions pane, select Create Cluster.

    

4. On the Before You Begin page, click Next.

5. On the Select Servers or a Cluster page, in the Enter name field, enter the NetBIOS name or the fully qualified domain name of all servers that you plan to add as failover cluster nodes, and then click Next.

6. On the Access Point for Administering the Cluster page, in the Cluster Name field, enter the name that you want to use to administer the cluster.

7. Select the checkboxes next to each network that you want to use for cluster management, and then select the Address field next to each selected network and enter the IP address that you want to assign to the cluster, and click Next.

    

8. Click Next to create the failover cluster.

9. On the Summary page, confirm that the failover cluster was successfully created.

 

NOTE: This procedure must be performed only once on any of the servers that you want to add as failover cluster nodes. To be able to manage the failover cluster from other nodes, simply connect to the already created cluster in the Failover Cluster Manager using the cluster name or IP address.
