SQL Server 2008 Active-Passive/Active-Active Cluster Installation

Like SQL Server 2005, SQL Server 2008 supports clustering using both the Standard and Enterprise editions. The

Standard edition supports a two-node cluster, and the Enterprise edition supports the maximum number of nodes that

the OS supports

The biggest changes in SQL Server 2008 cluster is that you can now use DHCP for clustering and use IP addressesfrom different subnets for each side of the cluster. The ability to use IP addresses from different subnets is most

useful for creating multisite clusters, calledgeographically distributed clusters.

SQL Server Cluster Installation

Step 1: I hope you had done with all the pre-requisites required by cluster.If youre installing SQL Server 2008 in a

cluster on Windows 2003, youll need to download and install the hotfix specified in the Microsoft article

athttp://support.microsoft.com/kb/937444 before you can install SQL Server 2008.

Note: Installation of above hotfix requires a reboot, so you have to cancel out of the installer at this point and restart

the process after installing that hotfix on all your cluster nodes.

Step 2: Open SQL Server 2008 installation executable file from your CD\DVD\Shared location

Double click on installation.exe and you will find the below screen. Now select New SQL Server Failover Cluster

installation option highlighted as in below image. (Note: For standalone installation we have to select standalone

option)

Step 3: Once you have selected Step 2 option, installation will check for setup support rules to identify the problem.

If it is failed due to any reason, you have to correct the issue. Please find the below screen shot. If it passed click on

OK command button.

Step 4: Installation wizard will install the setup support files, click on Install command button

Step 5: This step will walk you through all the required information as below. Click on Next button

1. Product Key

2. Licence Terms

3. Feature Selection

4. Disk Space Reuirements

5. Error and Usage Reporting

6. Cluster instllation Rules

7. Ready to install

8. Installation Progress

Step 6: Enter Product Key or It will take automatically. See the below image for it.

Step 7: Select required features, which you want install.


5/11

Step 8: Specify the Network Name/Virtual Name for SQL Server to failover. As we are installing Active-Passive cluster

we have to specify one virtual/network name. (Note: For Active-Active clustering you have specify different network

names as per the number of nodes)

Step 9: SQL Server will review the disk space requirement for the features you have selected


6/11

Step 10: This step will create a new cluster resource group for your SQL server failover. Please see the note in the

image.

Step 11: Select shared cluster disk resources for your SQL Server failover cluster


7/11

Step 12: Here you have to select network resources for your SQL Server failover cluster. You have to add IP address

as well.

Step 13: Here you have to specify the service account for SQL Server services. It is a best practice always keeps SQL

Services in cluster in manual mode

Step 14: Specify the authentication more and SA password in account provisioning tab, configure the location of the

data files, log files, temp database in data directories tab and enable file stream as per the requirement

Step 15

Step 14: Specify the authentication more and SA password in account provisioning tab, configure the location of the

data files, log files, temp database in data directories tab and enable file stream as per the requirement

Step 15: Select check boxes as per your requirement, I havent checked any option. Proceed with the next button


10/11

Step 16: Installation wizard will check the cluster installation rules, please correct if you found any failure and

proceed with the next button

Step 17: Now your SQL Server cluster is ready to install. Click on Install button


11/11

Step 18: Apply the required Service Pack/Patch and reboot the server

Step 19: Once installation is done on this node, we have to proceed with the installation of SQL Server on the other

cluster nodes. SQL Server 2005 was the last edition of SQL Server to automatically install SQL Server on all nodes at

once. Beginning with SQL Server 2008, we must manually install and patch each cluster node individually. This

process allows for less downtime as we are patching the cluster or upgrading your cluster from SQL Server 2005 to

SQL Server 2008.

Step 20 Installation on the other nodes is similar to installing on the first node except that we have select theAdd

Node to a SQL Server failoverclusteroption from the initial menu. The same software requirements apply to the

other nodes in the cluster, so the installer will handle the verification and installation of these components as well.

Because most of the settings are picked up from the other node(s) in the cluster that already have SQL Server

installed on them, the process of adding a node to the cluster is bit shorter than installing on the first node

Step 21 Installation on the other nodes is similar to installing on the first node except that we have select

theAdd Node to a SQL Server failover clusteroption from the initial menu. The same software

requirements apply to the other nodes in the cluster, so the installer will handle the verification and

installation of these components as well.

Because most of the settings are picked up from the other node(s) in the cluster that already have SQL
