Contributors netapp-pcarriga

You can add a controller asset to the management node configuration using the REST API UI.

You might need to add an asset if you recently scaled your installation and new assets were not added automatically to your configuration. Use these APIs to add assets that are recent additions to your installation.

What you'll need

  • Your cluster version is running NetApp Element software 11.3 or later.

  • You have deployed a management node running version 11.3 or later.

  • You have created a new NetApp HCC role in vCenter to limit the management node services view to NetApp-only assets. See Create a NetApp HCC role in vCenter

    1. Open the inventory service REST API UI on the management node:

      https://<ManagementNodeIP>/inventory/1/

    2. Select Authorize and complete the following:

      1. Enter the cluster user name and password.

      2. Enter the client ID as mnode-client.

        "self": "https://10.111.217.111/inventory/1/installations/abcd01e2-ab00-1xxx-91ee-12f111xxc7x0x"
      },
