| # 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. To start with a cluster aware installation (active/passive) of ERP LN, it is required to start with a normal cluster installation on the first cluster node. This node must own the cluster disk where ERP LN need to be installed. 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. How to install ERP LN on a cluster Start the Installation as described in the Overall installation Guide for Infor 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 LN installation as described in the Overall installation Guide for Infor 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 starting the Installation Wizard on the second and subsequent nodes for a minimal cluster installation. You have to use the same environment name for all nodes, which are part of the cluster. 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. Use the Windows tools to move the used disk drive resource to the current cluster node. It is required the disk is owned by the current cluster node. Click Yes, the Setup Type dialog will appear. You can now continue with the installation as described in the overall installation guide. The Installation Wizard will create a Baan Environment resource in the cluster manager in the same group as where the drive exists and where the BSE is installed. For example, if the BSE environment is `T:\Infor\bse`, and drive T: is member of cluster group Group 1, then the Baan Environment resource will be created in Group 1. After the installation on the first node has finished, you must run the Installation Wizard (can be done in parallel) on every other following node. Use the so-called 'minimal cluster' installation. The minimal cluster installation will prepare the required steps to make the node aware of the ERP LN installation. Installation on following cluster nodes On each of the other nodes of the cluster, check the following procedure to run a minimal install of LN on that node. Do not move the ownership of the disk on which 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 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. |
