Upon completing the deployment of the Aria Operations for Networks platform appliance with the X-Large brick size, the following error appears in the UI, as shown in the screenshot:

This is expected behavior. Even if the X-Large brick size is selected during deployment, vCenter initially allocates only 1 TB of disk space.
If you select the X-Large deployment configuration, you must manually add an additional 1 TB disk after completing the deployment to meet the system requirements for the XL brick size which is 2 TB.
Refer to the documentation on 'How to Increase the Disk Size' for step-by-step guidance.
After adding the additional disk size to meet the brick size of the platform VM, you must reconfigure the platform VM.
