If you receive a warning message that multiple generation IDs were detected for a specific suffix, you must re-initialize one or more replicas. If the warning is presented from a server after an initialization, it could be that the post-external-initialization command was not run as part of a global change in data.

Try the following fixes as needed.

  • To re-initialize replicas as part of a global change in data, run the post-external-initialization command.
  • To fix mismatchd generation IDs, run the dsreplication command.
  • To warn when any generation IDs are different across the topology, run the dsreplication tool with the status command.
