Restoring a volume in a mirror relationship

Contributors netapp-ivanad

For a version-independent mirror relationship, you can use System Manager to restore Snapshot copies to a source volume or to other volumes if the source data is corrupted and is no longer usable. You can replace the original data with the Snapshot copies in the destination volume.

Before you begin
  • The SnapMirror license must be enabled on both the source cluster and the destination cluster or on the nodes that contain the source volume and destination volume.

  • The source cluster and destination cluster must be in a healthy peer relationship.

  • The source aggregate or any other aggregate that you select for the restore operation must be a 64-bit aggregate.

  • If you are connecting from a cluster running ONTAP 9.2 or earlier to a remote cluster on which Security Assertion Markup Language (SAML) authentication is enabled, password-based authentication must also be enabled on the remote cluster.

About this task
  • You cannot restore a volume that is in a mirror relationship between a source storage virtual machine (SVM) and a destination SVM in a MetroCluster configuration.

  • You cannot perform a restore operation on SnapLock volumes.

  • You can restore a mirror relationship between sync-source SVMs in a MetroCluster configuration.

  • You can restore a mirror relationship from a volume on a sync-source SVM to a default SVM.

  • You can restore a mirror relationship from a volume on a default SVM to a DP volume on a sync-source SVM.

Steps
  1. Click Protection > Volume Relationships.

  2. Select the mirror relationship, and then click Operations > Restore.

  3. In the Restore dialog box, restore the data to the source volume in the mirror relationship or select any other volume:

    If you want to restore the data to…​ Do this…​

    The source volume

    1. Select Source volume.

    2. Go to Step 7.

    Any other volume

    Select Other volume, and then select the cluster and SVM from the list.

  4. Restore the data to a new volume or to an existing volume:

    If you want to restore the data to…​ Do this…​

    A new volume

    If you want to change the default name, displayed in the format destination_SVM_name_destination_volume_name_ restore, specify a new name, and then select the containing aggregate for the volume.

    An existing volume

    Select the Select Volume option.

    You must select a volume other than the source volume, or a read/write volume with some data in it and with a common Snapshot copy.

    Only those volumes with the same language attribute as the source volume are listed.

  5. Select either the latest Snapshot copy or the specific Snapshot copy that you want to restore.

  6. Select the confirmation checkbox to restore the volume from the Snapshot copy.

  7. Select the Enable Network Compression checkbox to compress the data that is being transferred during the restore operation.

  8. Click Restore.
