Hosting a Report Server Database in a SQL Server Failover Cluster

SQL Server provides failover clustering support so that you can use multiple disks for one or more SQL Server instances. Failover clustering is supported only for the report server database; you cannot run the Report Server service as part of a failover cluster.

To host a report server database on a SQL Server failover cluster, the cluster must already be installed and configured. You can then select the failover cluster as the server name when you create the report server database in the Database Setup page of the Reporting Services Configuration tool.

Although the Report Server service cannot participate in a failover cluster, you can install Reporting Services on a computer that has a SQL Server failover cluster installed. The report server runs independently of the failover cluster. If you install a report server on a computer that is part of a SQL Server failover instance, you are not required to use the failover cluster for the report server database; you can use a different SQL Server instance to host the database.

So on a Active passive node follow below steps,

1) On active node we already selected reporting services and installed
2) On passive node there is no Reporting services installed as its not a clustered feature
3) Install Reporting services as a named instance
4) configure RS with clustered name of SQL Server, by using existing URL and Report Server DB
5) Take a backup of encryption key and restore on passive node.
6) Now we can access the reports on Fail over.
