This is basically a problem of DNS. The present DNS server for grid-xx is 192.168.0.50, using the nscd server. Therefore first check if the server in 192.168.0.50 is open, otherwise "systemctl restart nscd".
- You need also check /etc/nsswitch.conf in the host (the machine you want to find grid-xx), to make sure DNS is used.
- You need also check /etc/resolve.conf, to make sure the local DNS server is there.
- For centos 7, make sure 192.168.0.50 has been added into /etc/sysconfig/network-scripts/if-xx
server side
- When you add a new host name in grid-0, then you need restart dnsmasq: systemctl restart dnsmasq to make the name available.
