ONTAP tools for VMware vSphere 10

Scale up ONTAP tools and enable High Availability

Use ONTAP tools Manager to scale up your appliance and configure High Availability (HA). By default, ONTAP tools for VMware vSphere deploys as a single-node, non-HA configuration.

Before you begin

  • Ensure that your OVA template matches the version of Node 1 (the initial deployment node).

  • Enable CPU hot add and memory hot plug on the hypervisor. These features are required to scale up the appliance and enable HA. For ONTAP tools 10.6 and later, these features are enabled by default. For earlier versions, enable these features before scaling up or enabling HA.

  • In vCenter Server, set the Disaster Recovery Service (DRS) automation level to partially automated. Revert to fully automated after HA deployment completes.

    Note You can only increase node size, not decrease it. Extra small (XS) deployments limit certain services.
Steps

  1. Launch ONTAP tools Manager: https://<ONTAPtoolsIP>:8443/virtualization/ui/

  2. Log in with your ONTAP tools administrator credentials.

  3. Select Edit Appliance Settings from the overview section.

  4. In the Configuration section, select your new node size and toggle the HA switch to enable High Availability.

  5. On the HA settings page, verify the following:

    • The content library resides on the same vCenter Server where the ONTAP tools VMs will run.

    • The ONTAP tools VMs are deployed on a cluster or resource pool, not directly on an ESXi host.

      Important After you enable HA, you cannot revert to a non-HA single-node configuration.

  6. In the HA settings section, enter the network details for Nodes 2 and 3. ONTAP tools supports three nodes in HA mode.

    ONTAP tools pre-fills most fields with Node 1 network settings. You can edit these values before completing the wizard. IPv6 address entries are only available if IPv6 is enabled on the management node. Ensure each ESXi host hosts only one ONTAP tools VM.

  7. Review the summary and click Save.

Result

The appliance begins scaling and HA enablement. Monitor progress on the Overview page or track the job from the Jobs view using the job ID.

If HA deployment fails with a status of 'New', delete the failed VM in vCenter and retry.

Review the Alerts tab for any warnings or issues during the process.
