Nutanix on HPE ® ProLiant ® 4. General Best Practices | 14 4.2. Cluster Expansion Cluster expansion with HPE ProLiant DX systems is simple and straightforward. HPE ProLiant DX nodes come from the HPE factory with Nutanix software preinstalled. When the node arrives, connect it to the cluster's network so that the CVM is reachable. Then use Prism to perform a cluster expansion operation as you would with Nutanix NX systems. If the factory-installed versions of the AOS and hypervisor software on the new node differ from the versions running on the cluster, this process installs the versions running on the cluster on the new node. Expanding a Nutanix cluster on HPE ProLiant DL systems currently requires two steps: 1. If the new server has not already been imaged, use the standalone Foundation VM to image it with the correct hypervisor and AOS version. Image the node, but do not add it to any cluster during the Foundation process. 2. Use Prism or the Nutanix command line interface (nCLI) in the existing ProLiant cluster to discover the newly imaged node and add it to the cluster. Node discovery uses IPv6 multicast traffic between Nutanix CVMs, so configure the upstream network devices to allow this traffic between nodes. Additionally, Nutanix recommends placing the CVMs and hypervisor hosts in the native, or default, untagged VLAN. If the CVMs are in a tagged VLAN, place the node you want to add in this same VLAN before discovery. Tip: With HPE ProLiant systems, you must use the Foundation VM instead of CVM- based cluster expansion to support bare metal imaging. For ease of use, deploy the Foundation VM on the existing Nutanix cluster before adding nodes. 4.3. Node Replacement Node replacement consists of node addition and node removal. • Node addition: Node addition for HPE ProLiant DL servers uses the same process described in the cluster expansion section above. • Node removal: To remove the old node from the cluster, follow the Nutanix Prism Web Console Guide.
