[HCI 1.4] Expanding NetApp HCI storage resources

After deployment, you can expand and configure NetApp HCI storage resources using the NetApp Deployment Engine.

Before you begin

You have free and unused IPv4 addresses on the same network segment as existing nodes (each new node must be installed on the same network as existing nodes of its type).
You have one of the following types of accounts:
- The native Administrator account that was created during initial deployment
- A custom user account with Cluster Admin, Drives, Volumes, and Nodes permissions
You have performed the following actions with each new node:
- Installed the new node in the NetApp HCI chassis by following the installation and setup instructions available in the NetApp HCI Documentation Center
- Cabled and powered on the new node
You have the management IPv4 address of an already installed storage node. You can find the IP address in the NetApp Element Management > Cluster > Nodes tab of the NetApp Element Plug-in for vCenter Server.
Each new node uses the same network topology and cabling as the existing storage or compute clusters.

About this task

Note: The NetApp Deployment Engine does not support H610S storage nodes. To add H610S nodes to a new or existing NetApp HCI deployment, use the NetApp Element software web interface. For information about adding nodes using the Element web interface, see the Element Software User Guide.

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

Steps

Browse to the management IP address of one of the existing storage nodes:
```
http://<storage node management IP address>/
```
Log in to the NetApp Deployment Engine by providing the NetApp HCI storage cluster administrator credentials.
Click Expand Your Installation.
On the Welcome page, select No.
Click Continue.
On the Available Inventory page, select the storage nodes you want to add to the existing NetApp HCI installation.
Click Continue.
On the Network Settings page, perform the following steps:
1. Verify the information detected from the initial deployment.
2. 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:
  - 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.
  - In the Management IP Address field, enter a management IP address for the new storage node that is within the management network subnet.
  - In the Storage (iSCSI) IP Address field, enter an iSCSI IP address for the new storage node that is within the iSCSI network subnet.
3. Click Continue.
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.
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.
Click Add Nodes.
You can monitor the progress while NetApp HCI adds and configures the resources.
Optional: Verify that any new storage nodes are visible in the VMware vSphere Web Client.
