Run the lcm node recovery script. 
 

ssh into a working cvm and type: python /home/nutanix/cluster/bin/lcm/lcm_node_recovery.py <cvm ip failed node>

Dear Jeroen, 

Thanks for your reply, you have always been a great help, unfortunately as this issue was quite critical, I had to find option to fix this immediately before I could wait for your reply, started with my basic troubleshooting steps as below.

SSH was working fine the problem NODE and the CVM was pinging as well,

Did, acli host.list and found node was not schedulable.

checked the status service libvirtd status it was active running.

planned to reboot the AHV through Prism Element.

Reboot took a little bit longer than usual but worked perfectly fine.

Tried to migrate a VM on the host it migrated successfully.

Issue is solved now.
