=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.
|
|
With the B<-n> option, B<makedhcp> will create a dhcpd.conf file, including certain general parameters
|
|
such as a dynamic range and omapi configuration.
|
|
With a noderange or the B<-a> option, makedhcp will inject configuration data (via omapi) 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 it 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.
|
|
|
|
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>. See
|
|
the xcatdb man page for details about the database attributes.
|
|
|
|
Note: This command is not supported for AIX clusters.

|
|
=head1 OPTIONS
|
|
|
|
=over 12
|
|
|
|
=item B<-n>
|
|
|
|
Create a new dhcpd.conf file with a network statement for each network dhcpd should listen on.
|
|
The B<makedhcp> command will automatically restart dhcpd after this operation.
|
|
|
|
=item B<-a>
|
|
|
|
Define all nodes to the DHCP server. (Will only add nodes that can be reached, network-wise, by
|
|
this DHCP server.) The dhcpd daemon does not have to be restarted after this.
|
|
|
|
=item I<noderange>
|
|
|
|
Add the specified nodes to the DHCP server configuration.
|
|
|
|
=item [B<-s> I<statements>]
|
|
|
|
For the input noderange, the argument will be interpreted like dhcpd.conf text.
|
|
|
|
=item B<-a -d>
|
|
|
|
Delete all nodes from the DHCP server configuration.
|
|
|
|
=item B<-d> I<noderange>
|
|
|
|
Delete all nodes in the noderange from the DHCP server configuration.
|
|
|
|
=item B<-h>
|
|
|
|
Display usage message.

|
|
|
=head1 EXAMPLES
|
|
|
|
=over 3
|
|
|
|
=item 1.
|
|
|
|
Add the network definitions to DHCP by updating the dhcpd.conf file:
|
|
|
|
makedhcp -n
|
|
|
|
=item 2.
|
|
|
|
Define all nodes to the dhcp server:
|
|
|
|
makedhcp -a
|
|
|
|
=item 3.
|
|
|
|
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).
|
|
|
|
makedhcp node5 -s 'option root-path \"172.16.0.1:/install/freebsd6.2/x86_64\";'
