vRA, vRO, and the Mystery of the Missing VMs

As an IT professional, I’ve dealt with my fair share of unexpected issues and head-scratching problems. But last week, I encountered something that really had me stumped. A customer had an environment consisting of vSphere, vRA, and vRO, with the usual suspects of IAAS roles duplicated and sitting behind a load balancer.

While rewriting some vRO workflows and adjusting blueprints for them, I noticed something strange happening. When I destroyed test VMs through vRA, they weren’t always deleted from the vSphere inventory. Sometimes, the VMs would be moved to a folder in the inventory with the current date and time stamp appended as a suffix to the VM name.

I have to admit, this baffled me. I spent some time digging into the issue, only to find that the solution was quite simple once I knew what to look for. The customer had multiple Windows boxes with the IAAS/Web/Dem roles separated across them, and they had this setup duplicated and sitting behind their load balancer. The setting doDeletes had been configured on just one of the IAAS role boxes.

So, depending on which box serviced the request, the VM either got deleted or got moved. It was a simple fix, but it definitely caused some temporary head-scratching!

This experience reminded me of the importance of thoroughly reviewing and understanding all aspects of the environment before implementing any changes. It’s easy to overlook seemingly minor details, only to have them cause major issues down the line.

In this case, the solution was straightforward once I knew what to look for. But, it could have easily been a more complex issue that required a lot more time and effort to resolve.

I hope that by sharing this experience, others can learn from my mistake and avoid similar head-scratching situations in their own environments. As always, thorough planning and testing before implementing any changes is essential to ensure a smooth and successful outcome.
