Configure a single consistency group

Contributors

Consistency groups can be created with existing volumes or with new volumes. Once a volume is added to a consistency group, it cannot be added to another consistency group. A volume can be removed from a consistency group by deleting the volume or deleting the consistency group.

Create a consistency group with new volumes

Steps
  1. Select Storage > Consistency groups.

  2. Select +Add. then Using New LUNs.

  3. Name the consistency group. Designate the number of LUNs and capacity per LUN.

  4. Select the host operating system and LUN format. Enter the host initiator information.

  5. To configure protection policies, add a child consistency group, or show more options about host initiators, select More options

  6. Select Save.

  7. Confirm your consistency group has been created by returning to the main consistency group menu where it will appear once the ONTAP job completes. If you set a protection policy, look under the appropriate policy, remote or local, which should display a green shield with a checkmark.

Create a consistency group with existing volumes

Steps
  1. Select Storage > Consistency groups.

  2. Select +Add. then Using existing volumes.

  3. Name the consistency group and select the storage VM.

  4. Select the existing volumes to include. Only volumes that are not already part of a consistency group will be available for selection.

    If creating a consistency group with new volumes, the consistency group supports FlexVol volumes. Volumes with Asynchronous or Synchronous SnapMirror relationships can be added to consistency groups, but they are not consistency group-aware. Consistency groups do not support S3 buckets, MCC, or SVMs with SVMDR relationships.

  5. Select Save.

  6. Confirm your consistency group has been created by returning to the main consistency group menu where it will appear once the ONTAP job completes. If you have chosen a protection policy, confirm it was properly set by selecting your consistency group from the menu. If you set a protection policy, look under the appropriate policy, remote or local, which should display a green shield with a checkmark.
