Starting the SnapVault relationships with clustered Data ONTAP

You need to define a SnapMirror policy before you start a SnapVault relationship.

1. For storage systems running clustered Data ONTAP, you start the SnapVault relationships by running the following command.
   Example

   hana::> snapmirror policy create -vserver hana2b -policy SV_HANA
   hana::> snapmirror policy add-rule -vserver hana2b -policy SV_HANA -snapmirror-label daily -keep 20
   hana::> snapmirror policy add-rule -vserver hana2b -policy SV_HANA -snapmirror-label hourly -keep 10
   
   hana::> snapmirror policy show -vserver hana2b -policy SV_HANA
   
                      Vserver: hana2b
       SnapMirror Policy Name: SV_HANA
                 Policy Owner: vserver-admin
                  Tries Limit: 8
            Transfer Priority: normal
    Ignore accesstime Enabled: false
      Transfer Restartability: always
                      Comment: -
        Total Number of Rules: 2
                   Total Keep: 8
                        Rules: Snapmirror-label  Keep Preserve Warn
                               ----------------- ---- -------- ----
                               daily              20  false      0
                               hourly             10  false      0
   

   The policy must contain rules for all retention classes (labels) that are used in the Snap Creator configuration. The above commands show how to create a dedicated SnapMirror policy SV_HANA
2. To create and start the SnapVault relationship on the cluster console of the backup cluster, run the following commands.
   Example

   hana::> snapmirror create -source-path hana1a:hana_data -destination-path 
   hana2b:backup_hana_data -type XDP –policy SV_HANA
   Operation succeeded: snapmirror create the relationship with destination 
   hana2b:backup_hana_data.
   
   hana::> snapmirror initialize -destination-path hana2b:backup_hana_data -type XDP
