Increasing Amazon EC2 Limits for Unfolding
You may need to increase Amazon EC2 service limits if you are unfolding. The limits cannot be automatically detected before you unfold. To increase limits, use the AWS EC2 Console to create a case to avoid errors when you unfold.
From the EC2 VPC Console, you can go to VPC > Subnet to check the Teradata Database subnet to ensure there is a sufficient amount of free IPs available to support more nodes.
