=head1 DESCRIPTION
|
|
|
|
The B<makedhcp> command with the B<-n> option will create a dhcpd.conf file to allow xCAT to manage
|
|
the DHCP configuration, including certain general parameters such as a dynamic range and omapi configuration.
|
|
With a noderange, makedhcp will inject configuration data pertinent to the specified nodes that immediately
|
|
takes effect without a reset.
|
|
|
|
The B<makedhcp> command with the B<-a> option will create a dhcpd.leases file for all nodes. If the B<-d> flag is used with the B<-a> flag then it will delete all nodes dhcp service host definitions.
|
|
|
|
The B<makedhcp> B<-d> flag followed with a <noderange> will delete the dhcp server host definitons for the noderange.
|
|
|
|
The B<makedhcp> command also uses the following attributes from the xCAT database:
|
|
B<site.dhcpinterfaces>, B<site.domain>,
|
|
B<networks.dynamicrange>, B<networks.dhcpserver>
|
|
|
|
|
|

1. The following example, will cause dhcp on the next request to set root-path appropriately for only node5. Note some characters (e.g. ") must be doubly escaped (once for the shell, and once for the OMAPI layer).
|
|
|
|
I<makedhcp node5 -s 'option root-path \"172.16.0.1:/install/freebsd6.2/x86_64\";'>
|
|
|
|
2. The following example, will update the dhcpd.conf file.
|
|
|
|
I<makedhcp -n>
|
|
|
|
