Applies to

  • ONTAP 9.4+
  • SVM-DR

Answer

  • It is possible to create SVM-DR identity-preserve true relationships but it is not supported
  • Two identity-preserve true relationships are only supported for migration and It is mandatory to release the relationship afterworlds
  • The dual identity-preserve true relationships can cause data corruption and data loss
  • Starting with ONTAP 9.4, you can fan-out SVM-DR to two destinations only
  • By default, only one identity-preserve true relationship is allowed per one SVM.

Additional Information

  • If you have two relationships with identity-preserve true option, if you try to create a third fan-out relationship with or without identity-preserve the relationship will fail with the following error message:

Error: command failed: Failed to create Vserver relationship information. Reason: Source Vserver "vserver" is in a msid preserving DR relationship, but the specified destination Vserver was created earlier than Data ONTAP 9.0,and so does not support an msid preserving relationship. All the relationships must be of the same type. Delete and recreate the destination Vserver, and then try the command again.
