It's my workflow
1.create cluster peer

2.add mediator

3.create source svm,create volume,create lun

4.create destination svm,and volume with DP type

5.create vserver peer

6.in source cluster , Protection -> Overview -> Protect Consistency Group
But I can select only volume,can't select lun
is any step is wrong?

A consistency group is a collection of volumes that are managed as a single unit. Snapshots in consistency groups enable an entire application workload to be restored.

Consistency groups overview (netapp.com)

 

As the snapshots in NetApp/ONTAP works at Volume level, therefore you have to provide the Volume of the underlying LUN. More info in the link above.

First answer is correct.  Snapmirror is for volumes.  Volumes contain luns.  When you mirror the volume the lun will be in the destination.
