Nutanix Cluster is comprised of several critical software and hardware components. All communication happens on a IP network.
- CVM - Controller Virtual Machine (AOS)
- Hypervisor - (AHV | ESXi | Hyper-V | XEN)
- IPMI - (Out of band management for the hosts)
Each CVM communicates with its respective Hypervisor Host on a private IP network. Hosts and CVMs must be on the same subnet.
Before proceeding with any network related changes, on the CVM or Hypervisor hosts, it is recommended to perform a cluster health check. Following Nutanix KB outlines the steps to ensure your Nutanix Cluster is in a healthy and consistent state:
Checklist on verifying cluster health status
To change the IP Addresses, Net-Mask (subnet mask), Default gateway for your AHV hosts due to hardware re-location, network design changes, please follow the guidance from AHV Advanced Administration Guide:
