Title: Automating ISO Detachment in an Event-Driven Datacenter
Welcome to the first article in our Event-Driven Datacenter series!
If you’re one of those who receive a daily report listing virtual machines (VMs) with forgotten attached ISOs, you’re in the right place. While there are many ways to handle this issue, our focus is automation—so let’s dive into how we can streamline this process.

Introduction
If your inbox regularly greets you with reminders about VMs still connected to ISO files, it’s time to automate that cleanup. Automation not only saves time but also reduces human error and helps maintain a tidy virtual environment.
Before we get into the details, I highly recommend checking out this insightful article by Gavin Stephens: Using a Service-Oriented Architecture Approach to VCF Automation Orchestrator Development. It closely mirrors the strategy I’m about to outline.
One of the key takeaways from that article is the principle of failing fast—exiting a function early when a problem is detected. That’s why I make it a habit to use if()… throw() statements at the start of my functions to catch issues before they cascade.
Getting Started
I’ve already begun building a library of reusable classes and functions tailored for VMware Aria Orchestrator. You can find them on GitHub here: General Examples for VMware Aria Orchestrator.
Now, let’s walk through the steps required to automatically remove attached ISO files from VMs.
Steps to Remove Attached ISO Files:
1. Retrieve the CD-ROM device specifications from the VM.
2. Create a new CD-ROM device spec based on the retrieved information.
3. Reconfigure the VM using the new device spec.
4. If the VM prompts for confirmation to complete the operation, respond to the question programmatically.
Here’s a high-level diagram of the process:
