# Creating Relationships for Open Replication for Amazon FSx for NetApp ONTAP

For the Open Replication feature for Amazon FSx for NetApp ONTAP , you need to create a relationship.

The type of relationship that you create depends on the type of copy that you want to use.

Type of copy to use | Type of relationship to create
--- | ---
Vault/replica copy | SnapVault MirrorVault
Mirror copy | SnapMirror Version Flexible Mirror

To configure the relationships, use either the commands in the following procedure.

## Before You Begin

Verify that both the source volume and the target volume meet the following conditions:

- Are the same size

- Use the same volume language

## Procedure

Type the following commands on the destination storage virtual machine (that is, the Vserver).

1. To create a destination volume, type the following command:

       volume create -vserver $[destination SVM name] -volume $[volume name] -aggregate $[aggregate name] -size $[size of volume] -state $[online] -type $[DP] -language $[volume language] -space-guarantee $[none] -snapshot-policy $[none]

2. For each volume that is going to be replicated, create one of the following relationships:

   - To create a SnapVault relationship, type the following command:

          snapmirror create -type $[XDP] -policy $[XDPDefault] -source-path $[Source SVM]:$[Source Volume] -destination-path $[Destination SVM]:$[Destination Volume]

   - To create a MirrorVault relationship, type the following command:

         snapmirror create -type $[XDP] –policy $[Snapmirror policy with policy type mirror-vault] -source-path $[Source SVM]:$[Source Volume] -destination-path $[Destination SVM]:$[Destination Volume]

   Note

   The -type and -policy fields are optional when creating a MirrorVault relationship.

   - To create a Version Flexible Mirror relationship, type the following command

         snapmirror create –policy $[Snapmirror policy with policy type async-mirror] -source-path $[Source SVM]:$[Source Volume] -destination-path $[Destination SVM]:$[Destination Volume]

3. To initialize the relationship, type the following command:

       snapmirror initialize -destination-path $[Destination SVM]:$[Destination Volume]

## Results

The relationship is created on the target SVM array and accessible from the source array.
