Hi,

Refer SAP Installation guide in http://service.sap.com/instguides

I will give an overview about the installation process.

Basic setup of MSCS 5.2 for SAP involves 2 systems, we will name it as node A(First MSCS node) and B(Additional MSCS node)

3 Cluster groups should be created for SAP, Database, Quorum

MSCS should be configured between node A and B, test the cluster by moving the groups between node A and B. Its very important to note that, Quorum disk group should not be taken offline. If its goes offline there are chances of cluster getting crashed.

Steps to be followed for SAP Cluster Installation

 In Cluster Admin, move the disk groups and shared disks to first MSCS node.

 On the first MSCS node, install the MS SQL Server 2005 64-Bit

 In Cluster Admin, move the disk groups and shared disks to Additional MSCS node.

 On the Additional MSCS node, install the MS SQL Server 2005 64-Bit

 In Cluster Admin, move the disk groups and shared disks to first MSCS node.

 Install the Central Services Instance for ABAP (ASCS) on first MSCS node.

 Install the Central Services Instance for Java (SCS) on first MSCS node.

 Cluster the First MSCS node

 Install the Database Instance on the First MSCS node

 Cluster the Additional MSCS node

 Install Enqueue Replication Server for ABAP and Java(Optional)

 Install the Central Instance

 Install at least one Dialog Instance

Before starting the installation, make sure that system logged on as Cluster Administrator.

Hope it helps

Regards

Did you check the official installation guides at

http://service.sap.com/instguides?

They contain special sections what you need to do in order to install the system on a cluster.
