vRealize Automation 7.1 introduced silent installation functionality, which utilizes an answer file (ha.properties) at install time.

At the time of deployment, the vApp or VM components are provisioned, and then the vRealize Automation silent installation is performed. By utilizing the ha.properties answer file on the vRealize Automation appliance, a unique, single-tenant instance of vRealize Automation is configured for the associated customer.

 

It is important to note that the parameter values in the ha.properties file have to be updated programmatically in order to complete the silent installation procedure. One method of achieving this is to generate a version of the ha.properties files through a scripted procedure with the necessary values, and then copy this newly generated file to the vRealize Automation appliance prior to execution of the silent installation.
