"unexpected status 409" error seen when deploying VM-Series Firewall from Terraform templates for Prisma AIRS

• When deploying VM-Series Firewall from Strata Cloud Manager for Prisma AIRS, the following error is seen when running 'terraform apply'

Error: creating/updating Virtual Machine (Subscription: "XXX"
Resource Group Name: "xxxxxxx-ai-runtime"
Virtual Machine Name: "xxxxxxxx-vm-01"): performing CreateOrUpdate: unexpected status 409 (409 Conflict) with error: SkuNotAvailable: The requested VM size for resource 'Following SKUs have failed for Capacity Restrictions: Standard_DS3_v2' is currently not available in location 'japaneast'. Please try another size or deploy to a different location or different zone. See https://aka.ms/azureskunotavailable for details.

• Despite selecting Standard_D4_v3, the error still refers to Standard_DS3_v2, which suggests that the previous configuration may not have been fully cleared or updated.

• AIRS AI Runtime
• VM-Series Firewall on Azure
• Terraform
• Strata Cloud Manager

• Azure does not support specific instances in specific regions
• Terraform cache may remain even after changing the instance types in the templates

1. Adjusting the Strata Cloud Manager settings to Standard_D4_v3.
2. Modifying the instance type to the same in the Terraform configuration.
3. These changes will resolve the issue.
