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.

Is this for a production Nutanix install?

If so, I'd recommend that you open a ticket on, 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.
