How to force update hostname map in hosts?

dhcp-server

#1

Hi, All
After set set service dhcp-server hostfile-update
If i have a host got the hostfile map like host1 192.168.1.110,
Then I change the hostname from host1 to my-host1, but the hostfile map is not updated.
How to force udate the mapping?

Yours Sincerely!
