Link-local IPv6 addresses are not supported
Use Global addresses instead of link-local addresses.
Link-local addresses are ambiguous and cannot be used by DevOps Code ClearCase® to resolve link-local IPv6 addresses. ClearCase relies on host name and address translation APIs. These standard APIs do not provide adequate information to ClearCase for link-local IPv6 addresses. Global addresses are not ambiguous. The host name API provides the information required for DevOps Code ClearCase to use these addresses. Set up your DNS and hosts tables to return global IPv6 addresses for your ClearCase nodes.
