Expanding NetApp HCI storage resources

After deployment, you can expand and configure NetApp HCI storage resources using NetApp Hybrid Cloud Control.

Before you begin

Tip: When expanding storage resources, storage capacity should be split evenly across all chassis for the best reliability.


  1. Open a web browser and browse to the IP address of the management node. For example:
  2. Log in to NetApp Hybrid Cloud Control by providing the NetApp HCI storage cluster administrator credentials.
  3. In the Expand Installation pane, Click Expand.
    The browser opens the NetApp Deployment Engine.
  4. Log in to the NetApp Deployment Engine by providing the NetApp HCI storage cluster administrator credentials.
  5. On the Welcome page, select No.
  6. Click Continue.
  7. On the Available Inventory page, select the storage nodes you want to add to the existing NetApp HCI installation.
  8. Click Continue.
  9. On the Network Settings page, some of the network information has been detected from the initial deployment. Each new storage node is listed by serial number, and you need to assign new network information to it. For each new storage node, perform the following steps:
    1. If NetApp HCI detected a naming prefix, copy it from the Detected Naming Prefix field, and insert it as the prefix for the new unique hostname you add in the Hostname field.
    2. In the Management IP Address field, enter a management IP address for the new storage node that is within the management network subnet.
    3. In the Storage (iSCSI) IP Address field, enter an iSCSI IP address for the new storage node that is within the iSCSI network subnet.
    4. Click Continue.
      Note: NetApp HCI might take some time to validate the IP addresses you enter. The Continue button becomes available when IP address validation is complete.
  10. On the Review page in the Network Settings section, new nodes are shown in bold text. If you need to make changes to information in any section, perform the following steps:
    1. Click Edit for that section.
    2. When finished making changes, click Continue on any subsequent pages to return to the Review page.
  11. Optional: If you do not want to send cluster statistics and support information to NetApp-hosted Active IQ servers, clear the final checkbox.
    This disables real-time health and diagnostic monitoring for NetApp HCI. Disabling this feature removes the ability for NetApp to proactively support and monitor NetApp HCI to detect and resolve problems before production is affected.
  12. Click Add Nodes.
    You can monitor the progress while NetApp HCI adds and configures the resources.
  13. Optional: Verify that any new storage nodes are visible in the VMware vSphere Web Client.
