vRealize Automation 7.x – preCheck

In my daily work, I am an SME responsible for building infrastructure based on vRealize without using vRealize LCM. To avoid wasting time checking the servers provided by other teams, I decided to create a simple script that based on the official requirements of the VMware documentation sets the required parameters.

Currently, the script is under development so you can consider it as a beta version but it meets your expectations. The element that has to be improved is integration with the user
