Silent vRealize Automation installations require that you prepare a text-based answer file in advance.
All newly deployed vRealize Automation appliances contain a default answer file.
To perform a silent installation, you must use a text editor to customize the settings in ha.properties to the deployment that you want to install. The following examples are a few of the settings and information that you must add.
Your vRealize Automation or suite license key
vRealize Automation appliance node FQDNs
vRealize Automation appliance root user account credentials
IaaS Windows server FQDNs that will act as Web nodes, Manager Service nodes, and so on
vRealize Automation service user credentials, a domain account with administrator privileges on the IaaS Windows servers
Load balancer FQDNs
SQL Server database parameters
Proxy agent parameters to connect to virtualization resources
Whether the silent installer should attempt to correct missing IaaS Windows server prerequisites
The silent installer can correct many missing Windows prerequisites. However, some configuration problems, such as not enough CPU, cannot be changed by the silent installer.
To save time, you can reuse and modify an ha.properties file that was configured for another deployment, one where the settings were similar. Also, when you install vRealize Automation non-silently through the Installation Wizard, the wizard creates and saves your settings in the ha.properties file. The file might be useful to reuse and modify for silently installing a similar deployment.
The wizard does not save proprietary settings to the ha.properties file, such as passwords, licenses, or certificates.
