A company is setting up FlexCache in CVO to scale-out an on-premises system.

When setting up FlexCache in Cloud Volumes ONTAP (CVO) to scale out an on-premises system, the critical first step on the on-premises system is to generate a cluster peering passphrase. This passphrase is used to establish a secure cluster peering relationship between the on-premises ONTAP system and the CVO in the cloud. Here's the process:

Cluster Peering Setup:Cluster peering is essential for FlexCache because it allows the on-premises system to communicate and share data with the CVO instance. The cluster peering passphrase is used to authenticate the peering session, ensuring security.

Generate the Passphrase:In the ONTAP system manager on the on-premises cluster, navigate to the cluster peering settings and generate or configure the passphrase that will be used for peering with the CVO.

Establish Peering:Once the passphrase is set, use it to create the cluster peer relationship from the on-premises ONTAP to the CVO, following the guided steps in ONTAP System Manager or using CLI commands.

For detailed instructions on setting up cluster peering for FlexCache, refer to the NetApp documentation on FlexCache and cluster peering: NetApp FlexCache Documentation.
