Caution: All the features that use the cluster virtual IP address will be impacted if you change that address. Do the following to change the virtual IP address of the cluster. The virtual IP address of the cluster is required to configure certain data protection features. You can change the virtual IP address of the cluster either before or after you change the CVM IP address. Nutanix recommends that you prepare a spreadsheet that includes the existing and new CVM, hypervisor host, and IPMI IP addresses, subnet masks, default gateway, and cluster virtual IP addresses and VLANs (download the IP Address Change Worksheet Template ). After you successfully reconfigure the IP addresses, update the reconfigured IP addresses at the remote sites before you resume the replications. If you have configured remote sites for data protection, either wait until any ongoing replications are complete or abort them. Follow the instructions in the Prism Web Console Guide, which describes how to designate the new VLAN or subnet for the backplane network. After you have updated the CVM and host IP addresses by following the steps outlined later in this document, you can then proceed to re-enable network segmentation. See the Prism Web Console Guide for your version of AOS to find instructions on disabling the network segmentation feature (see the Disabling Network Segmentation topic) before you change the CVM and host IP addresses. If you have enabled network segmentation on your cluster, check to make sure that the VLAN and subnet in-use by the backplane network is still going to be valid once you move to the new IP scheme. Typically, you do not need to change the IP addresses of the backplane interface (eth2) if you are updating the CVM or host IP addresses. The backplane network is always a non-routable subnet and/or VLAN that is distinct from the one which is used by the external interfaces (eth0) of your CVMs and the management network on your hypervisor. The network segmentation feature enables the backplane network for CVMs in your cluster (eth2 interface). Note the following if you are using the network segmentation feature. Verify if your cluster is using the network segmentation network_segment_status Therefore, plan the guest VM downtime accordingly. Guest VM downtime is necessary for this change, because the Nutanix cluster must be in a stopped state. If that is not possible and you must change the IP addresses of CVMs and hypervisor hosts, proceed with the procedure described in this document. X-Ray Performance & Reliability Tests 22īefore you decide to change the CVM, hypervisor host, and IPMI IP addresses, consider the possibility of incorporating the existing IP address schema into the new infrastructure by reconfiguring your routers and switches instead of Nutanix nodes and CVMs.NCM Intelligent Operations (formerly Prism Pro/Ultimate) 399.
