Issue:

Creation of SnapMirror relationship and consistency group initialization fails.

Solution:

Ensure that you have not exceeded the limit of consistency groups per cluster. Consistency group limits in SnapMirror active sync are platform independent and differ based on the version of ONTAP. See Object limits for guidance specific to your ONTAP version.

Error:

If the consistency group is stuck initializing, check the status of your consistency group initializations with the ONTAP REST API, System Manager or the command sn show -expand.

Important From ONTAP 9.8 through 9.14.1, SnapMirror active sync is referred to as SnapMirror Business Continuity (SM-BC).
Solution:

If consistency groups fail to initialize, remove the SnapMirror active sync relationship, delete the consistency group, then recreate the relationship and initialize it. This workflow differs depending on the version of ONTAP you are using.

If you are using ONTAP 9.9.1

If you are using ONTAP 9.10.1 or later

  1. Remove the SnapMirror active sync configuration

  2. Create a consistency group relationship then Initialize the consistency group relationship

  1. Under Protection > Relationships, find the SnapMirror active sync relationship on the consistency group. Select three stacked vertical dots icon, then Delete to remove the SnapMirror active sync relationship.

  2. Delete the consistency group

  3. Configure the consistency group
