Add/Remove disk action on VM in deployment will recreate the resources or custom resources even "ignoreChanges" value is set to "true" on cloud template.
Custom resources will get re-create on a VM deployment if you run Add/Remove disk day 2 action on Aria Automation even resource flags ignoreChanges:true are applied
Environment
VMware Aria Automation 8.x
Cause
Let's create a blueprint with vSphere machine and Custom resource. After deploying execute Add disk operation. This operation will fail because it tries to recreate the Custom resource because there is a difference for input of type Properties. The bp service expects Collection, but it receives LinkedHashMap. This is because the the vRO maps Properties to LinkedHashMap
Resolution
Issue will be fixed in future release of Aria Automation 9.0
