Installation of SQL Server 2005/2008 clusters on Windows 2003/2008

Installation SQL Server 2005/2008 failover clusters on MSCS Windows 2003/2008

The installation process between SQL Server 2008 and 2005 failover clusters are different.

With SQL Server 2008 in cluster you must run the setup process for SQL Server individually on each node of the failover cluster. To add a node to an existing SQL Server failover cluster, you must run SQL Server Setup on the node that is to be added to the SQL Server failover cluster instance : 

    Step 1 : Validation wizard
    Step 2 : Pre-check
    Step 3 : Installation of the first node
    Step 4 : Add a new node
    Step 5: Apply a service pack or hotfix on a SQL cluster

Whereas with SQL Server 2005 must run the setup from the active node. Then a silence installation will be performing automatically on each node.

Windows Server 2003/2008 MSCS validation

Before run the setup SQL Server installation, you must validate the hardware configuration by using the cluster validation wizard for Windows Server 2008 and the Windows Server Catalog ( to search for complete cluster solutions for previous Windows Server versions.

SQL Server 2008 failover clusters and stand-alone instances of SQL Server 2008 are not supported on Windows Server 2008 Server Core.

Before the installation
Before to start the installation, I invite you to read the documentation below:

Planning a SQL Server Installation  

Before Installing Failover clustering  

1.  The nodes must share a common disk subsystem.
2.  The nodes must live on the same local area network (LAN)/subnet.*
3.  The nodes must have a network heartbeat with low latency, less the 500ms.

* Separate subnets for cluster nodes: Although Windows Server 2008 failover clusters support separate subnets for cluster nodes, SQL Server 2008 failover clusters do not.

What versions of SQL are supported on Windows 2008 Server R2?
•  SQL Server 2005: SP3 is the minimum requirement for all editions of SQL Server 2005 with the exception of SQL Server 2005 Express.

•  SQL Server 2008: SP1 is the minimum requirement for all editions of SQL Server 2008 with the exception of SQL Server 2008 Express

Start the installation

Step 1: Pre-check the system to be ready for setup procedure :

o  Stop monitoring services (MOM or equivalent)
o  Stop anti-virus services
o  Verify that Terminal service is NOT running on any cluster node. Log off all Terminal Server/Remote Sessions from all secondary nodes before you start setup for SQL 2005.
o  Ensure that Windows Cryptographic Service Provider and Task Schedule service is running on all nodes.
o  Move disk resource (on which SQL Server will be installed) from 1 node to the other just to make a test.

Step 2: Run the SQL Server setup to properly install the instance :

o  Go on the node owning the targeted cluster group.
o  Use a local copy of the setup folder. Setup files should be based on active machine

Step 3: Post-installation checklist

Install the latest service pack for SQL Server in the article Microsoft Support Policies regarding SQL Server:
Move disk resource (on which SQL Server was installed) from 1 node to the other just to make a test  and Run the query below  :

Mover recurso de disco (en la que SQL Server se instaló) a partir del 1 de nodo a los demás para hacer una prueba y ejecutar la consulta a continuación: :

SELECT * FROM sys.dm_os_cluster_nodes
SELECT * FROM sys.dm_io_cluster_shared_drives
SELECT    SERVERPROPERTY('IsClustered') as _1_Means_Clustered ,
