Creating a SnapMirror relationship

You must create a SnapMirror relationship in the NetApp Element UI.

1. Click Management > Volumes.
2. Click the Actions icon for the volume that is to be a part of the relationship.
3. Click Create a SnapMirror Relationship.
4. In the Create a SnapMirror Relationship dialog box, select an endpoint from the Endpoint list.
5. Select if the relationship will be created using a new ONTAP volume or an existing ONTAP volume.
6. To create a new ONTAP volume in the Element UI, click Create new volume.
   1. Select the Storage Virtual Machine for this relationship.
   2. Select the Aggregate from the drop-down list.
   3. In the Volume Name Suffix field, enter a suffix.
      Note: The system detects the source volume name and copies it to the Volume Name field. The suffix you enter appends the name.
   4. Click Create Destination Volume.
7. To use an existing ONTAP volume, click Use existing volume.
   1. Select the Storage Virtual Machine for this relationship.
   2. Select the volume that is the destination for this new relationship.
8. In the Relationship Details section, select a policy. If the selected policy has keep rules, the Rules table displays the rules and associated labels.
9. Optional: Select a schedule.
   This determines how often the relationship creates copies.
10. Optional: In the Limit Bandwidth to field, enter the maximum amount of bandwidth that can be consumed by data transfers associated with this relationship.
11. Review additional details:

    State

    Current relationship state of the destination volume. Possible values are:

    • uninitialized: The destination volume has not been initialized.
    • snapmirrored: The destination volume has been initialized and is ready to receive SnapMirror updates.
    • broken-off: The destination volume is read/write and snapshots are present.

    Status

    Current status of the relationship. Possible values are idle, transferring, checking, quiescing, quiesced, queued, preparing, finalizing, aborting, and breaking.

    Lag Time

    The amount of time in seconds that the destination system lags behind the source system. The lag time must be no more than the transfer schedule interval.

    Bandwidth Limit

    The maximum amount of bandwidth that can be consumed by data transfers associated with this relationship.

    Last Transferred

    Timestamp of the last transferred snapshot. Click for further information.

    Policy Name

    The name of the ONTAP SnapMirror policy for the relationship.

    Policy Type

    Type of ONTAP SnapMirror policy selected for the relationship. Possible values are:

    • async_mirror
    • mirror_vault

    Schedule Name

    Name of the pre-existing schedule on the ONTAP system selected for this relationship.

12. To not initialize at this time, ensure that the Initialize check box is not selected.
    Note: Initialization can be time-consuming. You might want to run this during off-peak hours. Initialization performs a baseline transfer; it makes a snapshot copy of the source volume, then transfers that copy and all the data blocks it references to the destination volume. You can initialize manually or use a schedule to start the initialization process (and subsequent updates) according to the schedule.
13. Click Create Relationship.
14. Click Data Protection > SnapMirror Relationships to view this new SnapMirror relationship.
