Onboarding Aria automation deployed VM's fails with ' resource limits have been reached' error but the configured resource limits have space.

Products

• VMware Aria Suite

Issue/Introduction

Symptoms:

• The VM you are trying to onboard was once deployed from Aria automation and then unregistered for some reason.
• The deployed VM used a cloud template that used Aria Automation secrets as part of its YAML. You can confirm by going to discovered VM's custom properties and see if you can find an entry that references a secret.
• The issue occurs only if the 'Use Placements' option is enabled in the onboarding plan.

Environment

VMware Aria Automation 8.x

Cause

Caused by encrypted custom property which was left in the compute state from the previous deployment.

Resolution

VMware engineering is aware of this issue and it will be fixed in a future version where VM unregister will remote these custom properties.

Workaround:
As a workaround, you can try:
1. Onboarding from Assembler -> Resources -> Virtual Machines -> Discovered
You can initiate an onboarding from here. Note this is a quick onboarding and will not reflect against resource limits.

2. If you need resource limits to be counted against; do the above step, then unregister the VM again and re-onboard using the onboarding plan with the 'Use placements' option enabled. 

This will succeed as the quick onboarding disregards the custom properties from the VM and hence it is not an issue when re-onboarding using the onboarding plan.
