The following error message is displayed when host mapping conflicts with NetBackup:
Error in log: ..exited with status 7659: Connection cannot be established because the host validation failed on the target host
In Kubernetes deployment, communication to pod happens through multiple layers that is, load balancer, nodes and pod. In certain setups during communication host may get associated with certain IP and that gets changed in course of time. That IP may get associated with some different pod and can cause conflict. The host mapping entries is in the form of :ffff:<ip address>.
To resolve this conflict issue
- To verify the conflict entries, see Mappings for Approval tab section of NetBackup™ Security and Encryption Guide.
