Hello ,



Based on the description you've provided, it does sound like there may have been a removal or conversion of the Nutanix internal vSwitch on the ESXi hosts.



Please review the following KB on the Nutanix Support Portal.

Ahmed,

Is this for a production Nutanix install?



If so, I'd recommend that you open a ticket on portal.nutanix.com, so we can help you power through your issues and get you stable again.
Thanks Alot for your update , but i am sure that we didn't delete internal switch
If I had to bet, it would be that you tried changing the IP Addresses against the documented IP Change process, and the cluster didn't like that.



Please open a support ticket and we'll help you fix it.
How about:

1. SSH to new CVM IP and then change it back to orginial IP? You can do this by just "sudo ifconfig eth0 IP/netmask" command



2. Then restart the cluster again?



If not succeeded, I am afraid of having to recreate cluster again.
i already done this steps and not suceed to start cluster again after that i re-imaged cluster
Hi 



Did you find a solution to your issue?
no i didn't find solution to the issue So i have re-image all nodes and re-create cluster using foundation VM thanks you all for your Help
You should not have had to re-foundation the cluster.



Did you open a support case?



If so, can you please send me your ticket number to jon@nutanix.com? Happy to look into it.
