Cannot update maxDiskCapacityInGB on existing deployments in VMware Aria Automation

Products

• VCF Operations/Automation (formerly VMware Aria Suite)

Issue/Introduction

You are unable to increase the maxDiskCapacityInGB limit on existing deployments provisioned via VMware Aria Automation cloud templates. If a virtual machine is provisioned with a specific maxDiskCapacityInGB limit (for example, 100 GB) on the boot disk, you encounter validation errors when attempting to add an additional disk exceeding this limit or when trying to resize an existing disk.

You will observe the following errors in the user interface or logs:

UnableValidationException: Only disks with size less than 100 GB can be attached to compute
Disk disk002 resize 150 GB exceeded allowed capacity 100 GB

Environment

VMware Aria Automation

Cause

The maxDiskCapacityInGB property is hard-limited to the value defined at the time of initial provisioning. This property is locked on the deployed compute and disk resources based on the original template configuration.

Resolution

This is a known user experience limitation. There is no supported user interface method to update these custom properties on existing resources post-deployment.
