Here are the steps to change the Display name:

Before doing this check if all services are up. Also check that the data resiliency is good.

  1. Find current CVM name:

$ virsh list –all

  1. Shutdown CVM:

$ virsh shutdown

  1. Take XML dump of the CVM to preserve configuration changes Name the file appropriately, based on the new name of the CVM.

$ virsh dumpxml > NTNX–CVM.xml

  1. Undefine CVM

$ virsh undefine

  1. Modify the NTNX–CVM.xml file to use the new name:

 

NTNX–CVM

  1. Define the CVM

$ virsh define NTNX–CVM.xml

  1. Start the CVM.

$ virsh start NTNX–CVM

  1. Configure autostart in KVM so the CVM boots up with the host

$ virsh autostart NTNX–CVM

NCC: ncc health_check run_all might fail after upgrading

Source : Nutanix KB

ARTICLE NUMBER

000002511

Description

Note: This KB applies to NCC 2.0. For NCC 2.3 or later, please see KB 3620
Note: NCC 2.0 is not supported on NOS versions other than 4.1.3.

The ncc_health_checks run_all command might fail after NCC upgrade.

After running the checks, you might see the following messages:

Old NCC process found on the Controller VMs, Please contact Nutanix support
Old NCC process with PID 5855,6075,13707,13879,17667,17879,19887,20108,20673,20898,22677,22867found on

Solution

Log on to any Controller VM in the cluster and restart the Prism web console service.

Note: The cluster start command restarts the Prism service only in this case, not the entire cluster.

nutanix@cvm$ allssh ‘~/cluster/bin/genesis stop prism’

nutanix@CVM$ cluster start
Note: In a recent case we needed to reboot each CVM. This was after trying the genesis stop prism and killing pids with pkill.

In case you see multiple PIDs in each CVMs:

Old NCC process found on the cvms, Please contact Nutanix support
Old NCC process with pid 465,466,467,468,481,503,504,19356 found on 10.81.29.23

Check if email_alert is configured and if so, disable it.

How to check if NUMA is enabled on ESX hardware?

You can check it by using ESXTOP:

1. Run esxtop

2. Press “m” to enter on memory statistics

3. Press “f” to change the fields displayed

4. Press “f” again to show NUMA related fields

If numa is enables, you will see values (like, 0, 1, 2, etc for each node) on the NHN column, like this image:

numa_esxtop_good.jpeg

(In this picture there is a VM running on 2 NUMA nodes).

If not, you will see the “-” on the NHN column:

no_numa_esxtop_good.jpeg
There is also a command to check directly if there are and how many are the NUMA nodes:

esxcli hardware memory get | grep NUMA

 

How to identify if ESXi is installed to SD card or local HDD?

In the vSphere client, Hosts and Clusters View (assuming vCenter), highlight the host in question. Configuration > Hardware > Storage > Change to Devices view. For each device, look down under device details, Primary Partitions, and look for the device that lists several partitions, including several “Legacy MBR” and a “VMware Diagnostic” partition. This should be the device that ESXi is installed on.
