Let’s say that you ran the health checks on your cluster and received a failure under the component “cvm_name_check”, what does it mean and how do you fix it?

 

The NCC health check cvm_name_check ensures that any renamed CVMs (Controller VMs) conform to the correct naming convention to avoid issues with certain operations that depend on identifying the CVM from UVMs on the same host.

 

The default Controller VM naming is NTNX-<block_serial>-<position-in-block>-CVM.

The display name of the Controller VM must always:

  • Start with "NTNX-"; and
  • End with "-CVM"

To see how to modify the hostname of the Controller VM check out: https://portal.nutanix.com/#/page/kbs/details?targetId=kA032000000TUjkCAG

 

You followed the naming convention and the check is still showing a failure? This might be a false-positive alert depending on your AOS, contact Nutanix support for verification.
