Creating a mirror relationship from a source SVM

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

1. Click the SVMs tab.
2. Select the SVM, and then click Manage.
3. Click the Volumes tab.
4. Select the volume for which you want to create a mirror relationship, and then click Actions > Protect.
   The Protect option is available only for a read/write volume.
5. In the Create Protection Relationship dialog box, select Mirror from the Relationship Type drop-down list.
6. Optional: Select the Create version-flexible mirror relationship check box to create a mirror relationship that is independent of the ONTAP version running on the source cluster and destination cluster, and to back up the Snapshot copies from the source volume.
   If you select this option, the SnapLock volumes will not be displayed.
7. Specify the cluster, the SVM, and the destination volume.
8. 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.
9. Optional: Enter an alias name for the remote SVM in the Enter Alias Name for SVM dialog box.
10. 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, which is displayed in the format source_SVM_name_source_volume_name_mirror, specify a new name, and select the containing aggregate for the destination volume.
    Select an existing volume	Select the Select Volume option. Note: Only those volumes with the same language attribute as that of the source volume are listed.

    For Infinite Volumes, you can create a destination volume only if the destination SVM does not contain a volume.
11. 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	Click Create Policy. 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. Select the Transfer All Source Snapshot Copies check box to include the "all_source_snapshots" rule to the mirror policy, which will enable you to back up all the Snapshot copies from the source volume. Select the Enable Network Compression check box to compress the data that is being transferred. Click Create.

12. 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	Click Create Schedule. Specify a name for the schedule. 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. Click Create.
    You do not want to assign a schedule	Select None.

13. Select Initialize Relationship.
14. Click Create.
