=head1 NAME

B<makeconservercf> - creates the conserver configuration file from info in the xCAT database

=head1 SYNOPSIS

B<makeconservercf> [B<-V|--verbose>] [B<-d|--delete>] [I<noderange>]

B<makeconservercf> [B<-V|--verbose>] [B<-l|--local>] [I<noderange>]

B<makeconservercf> [B<-V|--verbose>] [B<-c|--conserver>] [I<noderange>]

B<makeconservercf> [B<-V|--verbose>] I<noderange> [B<-t|--trust>] I<hosts>

B<makeconservercf> [B<-h|--help|-v|--version>]


=head1 DESCRIPTION

The B<makeconservercf> command will write out the /etc/conserver.cf, using information from the nodehm table
and related tables (e.g. mp, ipmi, ppc).  Normally, B<makeconservercf> will write all nodes to the /etc/conserver.cf
file.  If a I<noderange> is specified, it will write only those nodes to the file.  In either case, if a node
does not have nodehm.cons set, it will not be written to the file.

If B<-d> is specified, B<makeconservercf> will remove specified nodes from /etc/conserver.cf file. If I<noderange> is not specified, all xCAT nodes will be removed from /etc/conserver.cf file. 

In the case of a hierarchical cluster (i.e. one with service nodes) B<makeconservercf> will determine
which nodes will have their consoles accessed from the management node and which from a service node
(based on the nodehm.conserver attribute).  The /etc/conserver.cf file will be created accordingly on
all relevant management/service nodes.  If B<-l> is specified, it will only create the local file.


=head1 OPTIONS

=over 10

=item B<-d|--delete>

Delete rather than add or refresh the nodes specified as a noderange.

=item B<-c|--conserver>

Only set up the conserver on the conserver host. If no conserver host
is set for nodes, the conserver gets set up only on the management node.

=item B<-l|--local>

Only run B<makeconservercf> locally and create the local /etc/conserver.cf.  The default is to also
run it on all service nodes, if there are any.

=item B<-t|--trust> I<hosts>

Add additional trusted hosts into /etc/conserver.cf. The I<hosts> are comma separated list of
ip addresses or host names. 

=item B<-v|--version>

Display version.

=item B<-V|--verbose>

Verbose mode.

=item B<-h|--help>

Display usage message.
