High availability (HA) deployment workflow
To increase resiliency and support more containers per service, expand your initial ONTAP tools deployment to a high-availability (HA) configuration. Enabling the VASA Provider service is required for vVols datastores in an HA setup.

You can scale up the ONTAP tools for VMware vSphere configuration to increase the number of nodes in the deployment and change the configuration to an HA setup.

To configure vVols datastores you must enable the VASA Provider service. Register the VASA provider with vCenter and ensure your storage policies meet the HA requirements, including proper network and storage configurations.
Enable the SRA services to use ONTAP tools Storage Replication Adapter (SRA) for VMware Site Recovery Manager (SRM) or VMware Live Site Recovery (VLSR).

If you're using vVol datastores with multiple vCenter Server instances, upgrade the self-signed certificate to a certificate authority (CA) signed certificate.
