yes, sorry, those two ones apply to 7mode only. Since you have Clustered Data Ontap, you just need to ensure you have enough permissions on source and destination VSM;
for instance, you can simply try passing SnapDrive the user "vsadmin" for both source and destination VSM's.
When configuring snapmirror with Clustered Data Ontap, the CLI would ask you to specify the Vserver name: you could ensure that the vserver DNS name is registered in DNS with the management LIF of the Vserver, though.
in case you still need to setu it up, I have made a list of steps you would typically follow for Snapmirror XDP (snapvault), in case it will turn useful:
0. Assuming you have already created source volumes and you have already setup lun’s and databases within those, Firstly, on your destination vserver, you need to create a destination volume of type DP, then setup SnapMirror XDP; here are some examples:
Vserver_dest::> vol create -volume vol_dest -aggregate aggrdata_2 -size 2g -state online -type DP -policy default -autosize-mode grow_shrink -space-guarantee volume -snapshot-policy none -foreground true
1. Create the snapmirror policy, as you are not going to use the default XDPDefault which we then need to assign to the snapmirror relationship:
Vserver_source::> snapmirror policy create -policy PolicymirrorStoD -tries 8 -transfer-priority normal -ignore-atime false -restart always -comment "this is a test SnapMirror Policy"
Vserver_source::> snapmirror policy add-rule -policy PolicymirrorStoD -snapmirror-label Daily -keep 21
Alternatively, you can also do this via the GUI, as shown in the below example:
2. Verify that the policy has been created successfully on source vserver:
Vserver_source::> snapmirror policy show -policy PolicymirrorStoD
Vserver: vserver_source
SnapMirror Policy Name: PolicymirrorStoD
Policy Owner: vserver-admin
Tries Limit: 8
Transfer Priority: normal
Ignore accesstime Enabled: false
Transfer Restartability: always
Create Snapshot: false

Total Keep: 100

-------------------------------- ---- -------- ----
Daily 100 false 0
3. Create snapmirror policy on secondary too (steps 1 and 2), or else when you later will run snapmirror create -vserver vserver_dest, you’ll get “Error: command failed: Policy lookup for " PolicymirrorStoD" failed”.
4. Create a volume snapshot policy: (By Design, you also need to associate the volume snapshot policy with the snapmirror labels created within the SnapMirror Policy)
Vserver_source::> volume snapshot policy create -policy SnapPolkeep2snaps -enabled true -schedule1 daily -count1 2 -snapmirror-label1 Daily
Verify:
Vserver_source::> volume snapshot policy show -policy SnapPolkeep2snaps
Vserver: Vserver_source
Snapshot Policy Name: SnapPolkeep2snaps
Snapshot Policy Enabled: true
Policy Owner: vserver-admin
Comment: -
Total Number of Schedules: 1
Schedule Count Prefix SnapMirror Label
---------------------- ----- --------------------- -------------------
daily 2 daily Daily
5. Associate the PRIMARY volumes involved in the snapvault with the new volume snapshot policy, which is linked to the snapmirror label(s):
Vserver_source::> volume modify -volume vol_source -snapshot-policy SnapPolkeep2snaps
Warning: You are changing the Snapshot policy on volume vol_source to SnapPolkeep2snaps. Any Snapshot copies on this volume from the previous policy will not be deleted by this new Snapshot
policy.
Do you want to continue? {y|n}: y
Volume modify successful on volume: vol_source
Vserver_source::>
Same for the second volume involved:
Verify:
Vserver_source::> vol show -volume vol_source -fields snapshot-policy
(volume show)
vserver volume snapshot-policy
----------- -------------- ---------------
Vserver_source vol_source SnapPolkeep2snaps
Vserver_source::>
6. create your first snapshot with the newly created label:
Vserver_source::> snapshot create -volume vol_source -snapshot testfornewlabel -foreground true -snapmirror-label Daily
Vserver_source::> snapshot create -volume vollogs_source -snapshot testfornewlabel -foreground true -snapmirror-label Daily
7. create and initialize snapmirror:
Vserver_dest::> snapmirror create -source-path Vserver_source:vollogs_source -destination-path Vserver_dest:vollogs_dest -type XDP -vserver Vserver_dest -throttle unlimited -policy PolicymirrorStoD
Vserver_dest::> snapmirror initialize -destination-path Vserver_dest:vollogs_dest -source-path Vserver_source:vollogs_source -type XDP
do this for every volume you want to snapvault.
On the destination VSM, Check that initialization has completed successfully, if not, repeat the step 0 and fix the problem:
Vserver_dest::> snapmirror show -destination-path Vserver_dest:vollogs_dest -source-path Vserver_source:vollogs_source
8. Now, on the secondary vserver, associate the snapmirror relationship (for each volume) to the newly created snapmirror policy:
Vserver_dest::> snapmirror modify -destination-path Vserver_dest:vol_dest-policy PolicymirrorStoD
9. When the first transfer is complete, you need to run SMSQL configuration wizard (if not done yet) and then setup a backup job from within SMSQL:
As you can see, SMSQL shows you multiple possible snapmirror labels which are pre-selectable; this means you should only create snapmirror labels with those names, respecting the case sensitivity.
10. now, SMSQL should retain 3 snapshots on primary and Ontap should ensure the Daily label is applied with 21 snapshots to be retained on the secondary volumes.
hope that helps,
Domenico Di Mauro.
