Are you someone with the following condition?

  1. Your Nutanix Cluster has grown so much that it needs to be moved to a different (bigger) network segment (VLAN). 

  2. You are daunted by the amount of changes that moving a cluster to a different network space could result in.

Have no fear!

The procedures are documented as per the CLUSTER IP ADDRESS CONFIGURATION section of the ACROPOLIS ADVANCED ADMINISTRATION GUIDE

From a high level, the procedures involve some preliminary verifications along with securing some downtime for the cluster (as the changes need to be made while the cluster is in a “stopped” state). From there, it is simply a matter of changing the IPMI and hypervisor IP addresses followed by the execution of a script called “external_ip_reconfig” which handles the procedures for changing the IP addresses of the CVMs. Follow that up with some post verifications and your existing cluster should be successfully running on a new network segment!
