These commands were
run under cDOT 8.2.3:

NetApp Release 8.2.3
Cluster-Mode: Fri Jan 16 01:07:00 PST 2015
Preliminary
Work
Firstly, verify that the primary and secondary Clusters
and SVMs are peered.
::>
cluster peer show
::>
vserver peer show
On the Primary
(Source) Cluster
Create a staging volume on an aggregate that belongs
to the same node as the volume to be SnapMirrored:
::>
vol create -vserver SVM -vol vol01_smtape_staging_src -aggregate N1_aggr1 -size
1050g -state online -type RW -junction-path /vol01_smtape_staging_src
N.B.: You may need
to make the volume slightly larger than the source volume.
Create a backup snapshot:
::>
volume snapshot create -volume vol01 -snapshot smt_1 -vserver SVM
Create an SMTAPE backup:
::>
set diag
::*>
system smtape backup -vserver SVM -volume vol01 -backup-snapshot smt_1
-file-path /SVM/vol01_smtape_staging_src/image
::*>
system smtape status show
Wait for the SMTAPE backup to complete. Create a CIFS
share (or could do an NFS export):
::*>
cifs share create -vserver SVM -share-name vol01_smtape_staging_src$ -path
/vol01_smtape_staging_src
And copy the image off onto disk.
N.B.: What the
image is copied to is beyond the scope of this post.
On the
Secondary (DR) Cluster
Create a staging volume on the DR SVM:
::*>
volume create -vserver SVMDR -volume vol01_smtape_staging_dst -aggregate
N1_aggr1 -size 1050g -state online -type RW -junction-path
/vol01_smtape_staging_dst
Create a share to the volume and copy on the backup
image:
::>
cifs share create -vserver SVMDR -share-name vol01_smtape_staging_dst$ -path
/vol01_smtape_staging_dst
Create a restricted volume to restore the image to:
::>
volume create -vserver SVMDR -volume vol01_dr -aggregate N1_aggr1 -size 1000g
-state restricted -type DP
Restore the volume:
::>
set diag
::*>
system smtape restore -vserver SVMDR -vol vol01_dr -file-path
/SVMDR/vol01_smtape_staging_dst/image
::*>
system smtape status show
When the SMTAPE restore is complete, resync primary and
secondary volumes:
::*>
snapmirror resync -source-path SVM:vol01 -destination-path SVMDR:vol01_dr
-source-snapshot smt_1
::*>
snapmirror show
