Before you begin
• Ensure that 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).
• Ensure that you have one of the following types of SolidFire storage cluster accounts:
◦ The native administrator account that was created during initial deployment
◦ A custom user account with Cluster Admin, Drives, Volumes, and Nodes permissions
• Ensure that you have performed the following actions with each new node:
◦ Installed the new node in the NetApp HCI chassis by following the
◦ Cabled and powered on the new node
• Ensure that 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.
• Ensure that each new node uses the same network topology and cabling as the existing storage or
compute clusters.

When you are expanding storage resources, storage capacity should be split evenly across
all chassis for the best reliability.
Steps
1. Open a web browser and browse to the IP address of the management node. For example:
https://[management node IP address]
2. Log in to NetApp Hybrid Cloud Control by providing the NetApp HCI storage cluster administrator
credentials.
3. Click Expand at the top right corner of the interface.
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, click No and click Continue.
6. On the Available Inventory page, select the storage nodes you want to add and click Continue.
7. 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 the new network
information to it. For each new storage node, complete the following steps:
a. Hostname: 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.
b. Management Address: Enter a management IP address for the new storage node that is within the
management network subnet.
c. Storage (iSCSI) IP Address: Enter an iSCSI IP address for the new storage node that is within the
iSCSI network subnet.
d. Click Continue.
