The vCLS virtural machine is essentially an “appliance” or “service” VM that allows a vSphere cluster to remain functioning in the event that the vCenter Server becomes unavailable. Once a host fails, another host will take over the services immediately and perform virtual machine failover. vCLS is activated when you upgrade to vSphere 7. Other reasons could be network issues or problems with the vpxa service. In fact, according to VMware, this is expected. Thus, the constraints are not enforced: DRS does evacuate virtual machines from hosts and place the hosts in maintenance mode or standby mode regardless of the impact this might have on failover. There is an issue with vSphere High Availability configuration for this cluster. 2. Upgrade the hardware on the hosts or add more hosts.
