/etc/init.d/hostd restart
vCenter Server 8.x
ESXi 8.x
Restarting hostd and vpxa via the /etc/init.d/hostd restart command causes a temporary loss of connectivity between vCenter Server and the ESXi host.
It is expected that the host will temporarily show as "Not Responding" while the /etc/init.d/hostd restart command is being executed.
