When you unconfigure a DHCP server or BOOTP relay agent, DHCP Manager takes the following actions:
Stops the DHCP daemon (in.dhpcd) process
Removes the links that enable automatic starting when the system boots
Removes the /etc/default/dhcp file, which records information about daemon startup and the data store location
The following figure shows the screen that is displayed when you choose to unconfigure a DHCP server.
When you unconfigure a DHCP server you must decide what to do with the DHCP data files: dhcptab and the DHCP network tables. If the data is shared among servers, you should not remove the dhcptab and DHCP network tables because this could render DHCP unusable across your network. Data can be shared through NIS+ or on exported local file systems. The file /etc/default/dhcp records the data store used and its location.
You can unconfigure a DHCP server while leaving the data intact by not selecting any of the options to remove data. Unconfiguring while leaving the data intact in effect disables the DHCP server.
If you are certain that you want to remove the data, you can select
an option to remove the dhcptab and network tables. If
you had generated client names for the DHCP addresses, you can also elect
to remove those entries from /etc/inet/hosts
or the
NIS+ hosts
table.
Before you unconfigure a BOOTP relay agent, be sure that no clients rely on this agent to forward requests to a DHCP server.
