Critical Prerequisite Tasks

Perform all critical tasks before you attempt to install the first data tier in your Microsoft Failover Cluster environment.

1. Set up the number of physical servers that your SAP Mobile Platform installation plan requires.
   Ensure that these hosts meet all the requirements specified in Supported Hardware and Software.
2. Have your IT support team set up and build a Microsoft Failover cluster with two server nodes on which you will install SAP Mobile Platform data tiers.
   Supply your IT support team with the names for the cluster and the two servers.
3. Acquire a license file, customized to reflect the SAP Mobile Platform configuration your company has purchased, from SAP Service Marketplace (SMP) or Sybase Product Download Center (SPDC), as described in Obtaining a License.
4. Install and configure a SySAM license server that can manages license information for all the data tiers and SAP Mobile Server nodes in your cluster.

   Note: You cannot use the unserved license model in a Microsoft Failover Cluster.

• Adding a Data Folder to the Cluster Share Disk
  Your IT team has created a share disk that will always be available to the active data tier node, as Microsoft Failover Cluster switches the data tier nodes between active and passive states. Create a data folder on that share disk.
• Verifying the Microsoft Failover Cluster Configuration
  Before you install the first data tier for SAP Mobile Platform, ensure that the Microsoft Failover Cluster is operating correctly. This simplifies the troubleshooting process for any issues that may arise during installation of SAP Mobile Platform components.
