To move several volumes containing iSCSI LUNs from an ONTAP AFF cluster to Cloud Volumes ONTAP (CVO), the most appropriate method is using SnapMirror. Here's the process:
* Utilizing SnapMirror for LUN Migration:SnapMirror is NetApp's replication technology that is ideally suited for efficiently transferring data between ONTAP systems, including from AFF to CVO. It is capable of handling complex data structures like iSCSI LUNs, ensuring data integrity and consistency during the transfer.
* Configuration of SnapMirror:Set up a SnapMirror relationship between the source AFF cluster and the destination CVO instance. This involves configuring the SnapMirror policy, scheduling the replication, and initializing the transfer of data.
* Advantages for iSCSI LUNs:SnapMirror maintains the layout and attributes of the iSCSI LUNs during replication, which is crucial for ensuring that the storage is ready for immediate use upon completion of the replication to the CVO environment.
For step-by-step instructions on configuring and using SnapMirror for transferring iSCSI LUNs, consult the NetApp documentation on SnapMirror: NetApp SnapMirror Documentation.

For configuring Cloud Backup Service (CBS) in a dark site to back up ONTAP volumes to StorageGRID, the necessary NetApp networking component to configure is the BlueXP Connector. The BlueXP Connector serves as a gateway to enable secure communication between on-premises environments and NetApp services, such as StorageGRID, especially in scenarios where direct internet connectivity is limited or non-existent (as in dark sites).
The BlueXP Connector acts as a local agent that facilitates the connection between your ONTAP systems and NetApp's cloud services without requiring direct internet access. This setup is crucial in dark site scenarios where security and network isolation are paramount. By configuring the BlueXP Connector, administrators can ensure that backup data is securely transmitted to StorageGRID, adhering to organizational security policies.
To implement this, follow these steps:
* Install and configure the BlueXP Connector in your environment.
* Ensure it has appropriate network access to both the ONTAP systems and the internal network that connects to StorageGRID.
* Configure CBS to use the BlueXP Connector for data transmissions to StorageGRID.
