In this example we will create two SVMs. The source_svm has a source_volume,
the dest_svm will have a dest_volume of the type DP.
The two SVMs will be peered. The cluster cl1 and cl2 are already peered.
We will create a lun in the source_svm and the volume will be snapmirrored
to the dest_volume.
The lun will be mapped to a windows machine from both SVMs. DR will be tested.

(output will be something like)

On windows, rescan disks
On windows, create a new simple volume in the lun and put some data in it

# check for the snapmirrored lun
