Running Status of a Consistency Group

Deleting a Consistency Group (Supported or Not)







To be recovered







  • The essence of deleting a consistency group is to delete the consistency group configuration information stored on both local and remote storage devices. In this way, the consistency group can be deleted.
  • If a remote replication link fails, you must forcibly delete the consistency group from the local and remote devices respectively.
  • After a consistency group is deleted, you cannot centrally manage the remote replication pairs in the group.


  1. Log in to DeviceManager.
  2. Go to the remote replication consistency group page.

    The operation path varies with user types:

    • System user: Click vStore, select the desired vStore, and click Details to go to the vStore view. Choose Data Protection > Remote Replication > Remote Replication Consistency Group.
    • vStore user: In the vStore view, choose Data Protection > Remote Replication > Remote Replication Consistency Group.

  3. Right-click the desired consistency group and choose Delete.

    The security alert dialog box is displayed.

  4. Confirm the operation of deleting the consistency group.

    1. Select Only delete the configuration information about the local device if the local device is disconnected from the remote device based on the situation.
      • This option is applicable to scenarios where the physical link between the local storage system and remote storage system is disconnected. In such scenarios, this option is mandatory. Otherwise, the group cannot be deleted.
      • If you want to delete the configuration information of the consistency group from the remote storage device, you must perform this operation on the remote storage device.
      • If the physical link is normal, do not select this option.
    2. Carefully read the contents of the dialog box. Select I have read and understand the consequences associated with performing this operation. Click OK to confirm the information.

      The Success dialog box is displayed, indicating that the operation succeeded.

    3. Click OK.
