ONTAP 9

to Japanese version

Failure creating a SnapMirror relationship and initializing consistency group

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 SM-BC are platform independent and differ based on the version of ONTAP. See Additional restrictions and limitations for limitations based on ONTAP version.

Error:

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

Solution:

If consistency groups fail to initialize, remove the SM-BC 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 9.8-9.9.1

If you are using ONTAP 9.10.1 or later

  1. Under Protection > Relationships, find the SM-BC relationship on the consistency group. Select three stacked vertical dots icon, then Delete to remove the SM-BC relationship.

  2. Delete the consistency group

  3. Configure the consistency group
