Create a relationship from an ONTAP source to an Element destination

Contributors netapp-pcarriga

Beginning with ONTAP 9.4, you can use the ONTAP CLI to create a relationship that uses SnapMirror to replicate snapshot copies of a LUN created on an ONTAP source back to an Element destination. You might be using the LUN to migrate data from ONTAP to Element software.

Before you begin

  • The Element destination node must have been made accessible to ONTAP.

  • The Element volume must have been enabled for SnapMirror replication.

About this task

You must specify the Element destination path in the form <hostip:>/lun/<name>, where “lun” is the actual string “lun” and name is the name of the Element volume.

Replication rules are as follows:

  • The replication relationship must have a policy of type “async-mirror”.

    You can use a default or custom policy.

  • Only iSCSI LUNs are supported.

  • You cannot replicate more than one LUN from an ONTAP volume to an Element volume.

  • You cannot replicate a LUN from an ONTAP volume to multiple Element volumes.

Step

  1. Create a replication relationship from an ONTAP source to an Element destination:

    snapmirror create -source-path <SVM:volume>|<cluster://SVM/volume> -destination-path <hostip:>/lun/<name> -type XDP -schedule schedule -policy <policy>

    For complete command syntax, see the man page.

    The following example creates a SnapMirror DR relationship using the default MirrorLatest policy:

    cluster_dst::> snapmirror create -source-path svm_1:volA_dst -destination-path 10.0.0.11:/lun/0005 -type XDP -schedule my_daily -policy MirrorLatest

    The following example creates a SnapMirror DR relationship using the custom my_mirror policy:

    cluster_dst::> snapmirror create -source-path svm_1:volA_dst -destination-path 10.0.0.11:/lun/0005 -type XDP -schedule my_daily -policy my_mirror
After you finish

Use the snapmirror show command to verify that the SnapMirror relationship was created. For complete command syntax, see the man page.
