Licensing Issues During Fold and Unfold

Licensing errors may occur when folding or unfolding a system. Nodes and the associated licenses are automatically removed from the system so new nodes and new licenses can be assigned. During this process, Teradata strongly suggests you monitor the AWS CloudWatch logs. See Accessing AWS CloudWatch Logs (look for log group Teradata/DBS/stack-name and log stream telm_stack-name). Teradata Database automatically fixes most issues and activates the new licenses. There may be a delay during this process.

Following are examples of errors and possible remedies:
Errors Remedies
