Contributors netapp-mwallis Download PDF of this page

If you physically replace a compute node or need to remove it from the NetApp HCI cluster, you must remove the compute node asset using the management node APIs.

What you’ll need
  • To use REST APIs, your storage cluster must be running NetApp Element software 11.5 or later and you must have deployed a management node running version 11.5 or later.

Steps
  1. Enter the management node IP address followed by /mnode/1/:

    https://[IP address]/mnode/1/
  2. Click Authorize or any lock icon and enter cluster admin credentials for permissions to use APIs.

    1. Enter the cluster user name and password.

    2. Select Request body from the type drop-down list if the value is not already selected.

    3. Enter the client ID as mnode-client if the value is not already populated.

    4. Do not enter a value for the client secret.

    5. Click Authorize to begin a session.

      If you get the Auth Error TypeError: Failed to fetch error message after you attempt to authorize, you might need to accept the SSL certificate for the MVIP of your cluster. Copy the IP address in the Token URL, paste the IP into another browser tab, and authorize again. If you attempt to run a command after the token expires, you get an Error: UNAUTHORIZED error. If you receive this response, authorize again.
  3. Close the Available authorizations dialog box.

  4. Click GET/assets.

  5. Click Try it out.

  6. Click Execute.

  7. Scroll down in the response body to the Compute section, and copy the parent and id values for the failed compute node.

  8. Click DELETE/assets/{asset_id}/compute-nodes/{compute_id}.

  9. Click Try it out.

  10. Enter the parent and id values you got in step 7.

  11. Click Execute.
