An installation file is required in order to drive future installs so need to manually install $U on 1 node (of each type) first. See section 3.4 in the installation manual and follow the steps to carry out a typical install and this will create an installation file. Use the switch /r to inform the installation procedure to create this file.
Once the file has been created this can be used as a template for future installations by changing the name of the node and host at the top of the file (given that everything else would be standard). Normal scripting variable substitution can be used for this to create the specific driver file.
For subsequent silent installs use the /s for silent switch to inform the install process to use a file created from the initial (master) install file.
