B<makedhcp> - Creates and updates DHCP configuration files.

=head1 DESCRIPTION
The B<makedhcp> command configures the DHCP daemon on the local system so that xCAT can manage the nodes of the cluster during discovery, full install, diskless booting, and normal booting.
The B<makedhcp> command creates and updates the DHCP configuration file on the local system.
The B<makedhcp> command is supported for both Linux and AIX clusters.
With the B<-n> option, B<makedhcp> will create a new dhcp configuration file. For Linux systems this will include certain general parameters such as a dynamic range and omapi configuration.
With the B<-n> option, B<makedhcp> will create a new dhcp configuration file. For Linux systems the file will include network entries as well as certain general parameters such as a dynamic range and omapi configuration. For AIX systems the file will include network entries.
Before using the B<-n> option make sure there is nothing in the configuration file that you wish to preserve. If a configuration file already exist the B<makedhcp> command will create a backup before creating a new one.
If a configuration file already exist the B<makedhcp> command will create a backup before creating a new one.
On AIX systems, if there are any non-xCAT entries in the configuration file they will be preserved and added to the end of the new configuration file.
With a noderange or the B<-a> option, B<makedhcp> will inject configuration data pertinent to the specified nodes that immediately takes effect without a restart of DHCP.
If the B<-d> flag is used with the B<-a> flag then B<makedhcp> will delete all nodes' dhcp host definitions. The B<-d> flag followed by a I<noderange> will delete the dhcp host definitons for the noderange.
On AIX systems B<makedhcp> will not add entries for cluster nodes that will be installed using NIM. The entries for these nodes will be managed by NIM.
The B<makedhcp> command also uses the following attributes from the xCAT database:
B<site.dhcpinterfaces>, B<site.domain>, B<site.nameservers>, B<networks.dynamicrange>, B<networks.dhcpserver>, B<networks.nameservers>. See the B<xcatdb> man page for details about the database attributes.
If the B<-d> flag is used with the B<-a> flag then B<makedhcp> will delete all the node entries created by xCAT. The B<-d> flag followed by a I<noderange> will delete the dhcp host definitons for the noderange.
Any entries created by NIM will not be removed.
