| # Microsoft Windows Server Cluster Before you start an installation on a Microsoft Windows cluster, you must prepare a cluster. Clusters are used for increasing the availability of a server. The server can be used for the Master Application Server (MAS) or Application Server (AS). The Installation Wizard takes care for some specific steps. This Chapter describes the installation of ERP LN on a Windows Server Cluster. The cluster installation uses DCOM. which can cause problems. For more specific information, refer to the trouble shooting section in this Chapter. After a cluster has been created with Microsoft Cluster Administrator, a virtual server name will exist with its own IP address. This virtual server name needs to be used during installation of ERP LN. Supply the cluster groups with meaningful names,such as ERP, Database, Quorum groups. How to install MS SQL Server on a cluster Microsoft SQL Server installations are version-dependant and system-dependant. For the specific installation procedure of the SQL version that you want to install, check your Microsoft SQL Server documentation. Select to install a failover Cluster in the MS SQL setup screen. Specific Cluster Notes There are no additional needs regarding the installation of MS SQL Server on a cluster, compared to a non-clustered server. The used collation in MS SQL server must meet the locale used later during installation of ERP LN. MS SQL Authentication mode, which is mixed Windows and MS SQL server authentication and other settings are identical to the needs for installing ERP LN on a normal, non-clustered, server How to install ERP LN on a cluster Start the Installation as described in the Overall installation Guide for Infor ERP LN products (U9498 US). Share the setup files between all nodes, as this will help you fill in the required data in the Installation Wizard. If sharing is not possible, use the same environment name and destination directory on all nodes of the cluster. When the installation files are in a shared disk or folder, the Installation Wizard automatically gathers the data filled during installation on the first node of the cluster. The differences between a normal installation and the installation on a cluster will be discussed in the following section. Installation on first cluster node Start the ERP LN installation as described in the Overall installation Guide for Infor ERP LN products (U9498 US). When the environment dialog appears, you have to fill in an environment name. For example; erplncluster. You need to remember this name later, when configuring the ERP LN cluster resources in the cluster administrator. When the Hostname dialog appears, you will see that the installer has detected that the current host is part of a Windows cluster. When the Destination Directory dialog appears, supply the name of the directory which will become the BSE directory. This directory must be on a cluster disk separate from the Quorum disk and separate from the MS SQL database disk. Notice that the installer mentions the available cluster disks. The Normal Windows cluster installation need only to be chosen for the first node when you run the Installation Wizard. For additional nodes, you need to select minimal Windows cluster porting set only installation. Click Next, if the following message appears, complete step 6: Cluster-capable drive S: is not available on this node, this install will be a minimal Windows Portingset installation, ok? Click No to return to the Destination Directory dialog. Here, use the Cluster Administrator to move the ownership of the selected disk to the current node: Click Yes, the Setup Type dialog will appear. You can now continue with the installation as described in the overall installation guide. After the installation is finished you must return at this point again. Installation on next cluster nodes On each of the other nodes of the cluster, check the following procedure to run a minimal install of ERP LN on that node. Do not move the ownership of the disk on which ERP LN was installed to the other node. These actions do not need to be done in sequence; they can run in parallel with one another, and with the installation of ERP LN on the first node. Use the same environment name as used on the first cluster node, refer to step 1 of Installation on first cluster node. This can be done when running the setup from the (shared) disk or directory. Run a minimal Windows cluster porting set only installation, refer to step 3 of Installation on first cluster node. Repeat all installation steps of the Installation Wizard for all nodes which are part of the Microsoft Windows cluster. |
