LiteSpeed does not operate as a cluster service, and you do not need to set up a cluster resource. Use the following installation instructions for both active-passive and active-active Microsoft Cluster Service or Failover installations.
Launch the .msi file on one node in the cluster. This node must have an install of each SQL Server instance on which you want to install LiteSpeed.
Choose “Install LiteSpeed to all nodes automatically” which is the default option. This is the recommended option for doing an initial installation to the cluster configuration.
To install LiteSpeed on a node only
If you have added a new node to an existing cluster configuration and want to install LiteSpeed to this new node only, run .msi on this particular node and use the “Install LiteSpeed to this node only” option.
Instance Configuration uses WMI to deploy the .msi file to all nodes. You do not need to run the installation from the passive nodes or failover any nodes of the cluster during the installation process. This process automatically upgrades any old version of LiteSpeed on any node.
If you have issues while running the Instance Configuration Wizard during installation, cancel out of the wizard and complete the installation without it. After the installation completes run the Instance Configuration Wizard from the Start menu and complete it.
