Creating a mirror relationship from a destination SVM

You can use System Manager to create a mirror relationship between a source volume and a destination volume from the destination Storage Virtual Machine (SVM), and assign a policy and schedule to the relationship. The mirror copy enables quick availability and restoration of data if the data on the source volume is corrupted or lost.

Before you begin

About this task

Steps

  1. Expand the Storage Virtual Machines hierarchy in the left navigation pane.
  2. In the navigation pane, select the SVM, and click Protection.
  3. In the Protection window, click Create > Mirror.
  4. In the Create Mirror Relationship from Destination window, select the cluster, the SVM, and the source volume.
  5. If the selected SVM is not peered, use the Authenticate link to enter the credentials of the remote cluster and create the SVM peer relationship.
  6. For FlexVol volumes, create a new destination volume or select an existing volume:
    If you want to... Do the following...
    Create a new volume If you want to change the default name, displayed in the format source_SVM_name_source_volume_name_, specify a new name and select the containing aggregate for the destination volume.
    Select an existing volume Select the Select Volume option.

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

    For Infinite Volumes, you can create a destination volume only if the destination SVM does not contain a volume.
  7. Select an existing policy or create a new policy:
    If you want to... Do the following...
    Select an existing policy Select a mirror policy from the list.
    Create a new policy
    1. Click Create Policy.
    2. Specify a policy name and set the schedule transfer priority.

      Low indicates that the transfer has the least priority and is usually scheduled after normal priority transfers. By default, the priority is set to normal.

    3. Select the Transfer All Source Snapshot Copies check box to include the "all_source_snapshots" rule to the mirror policy that will enable you to back up all the Snapshot copies from the source volume.
    4. Select the Enable Network Compression check box to compress the data that is being transferred.
    5. Click Create.
  8. Optional: Select the Create version flexible mirror relationship check box to create a mirror relationship that is independent of the Data ONTAP version running on the source and destination clusters and to back up the Snapshot copies from the source volume.
  9. Specify a schedule for the relationship:
    If... Do the following...
    You want to assign an existing schedule From the list of schedules, select an existing schedule.
    You want to create a new schedule
    1. Click Create Schedule.
    2. Specify a name for the schedule.
    3. Select either Basic or Advanced.
      • Basic: You can select this option to specify only the day of the week, time, and the transfer interval.
      • Advanced: You can select this option to specify a cron style schedule.
    4. Click Create.
    You do not want to assign a schedule Select None.
  10. Optional: Select Initialize Relationship to initialize the mirror relationship.
  11. Click Create.

Result

If you chose to create a new destination volume, then a new destination volume of type dp is created with the language attribute set to match the language attribute of the source volume.

A mirror relationship is created between the source volume and the destination volume. The base Snapshot copy is transferred to the destination volume if you have opted to initialize the relationship.
