=head1 Name

B<nodeset> - set the boot state for a noderange

=head1 B<Synopsis>

B<nodeset> [I<noderange>] [I<boot>|I<install>|I<stat>|I<iscsiboot>|I<netboot>|I<runcmd=bmcsetup>]

B<nodeset> [I<-h>|I<--help>|I<-v>|I<--version>]

=head1 B<Description>

B<nodeset>  sets the next cold or warm boot state for a single or range of
nodes or groups.  This tells xCAT what you want to happen the next time the
nodes are booted up.  See  L<noderange(3)|noderange.3>.   B<nodeset>  accomplishes  this  by
changing  the network boot files.  Each xCAT node always boots from the
network and downloads a boot file with instructions on what  action  to
take next.

B<nodeset> will maniputale the boot configuration files of yaboot and pxelinux.0.

Assume that /tftpboot is the root for tftpd (set in B<site(5)>).

B<nodeset> for pxe makes changes to /tftpboot/pxelinux.cfg/{node hex ip}

B<nodeset> for yaboot makes changes to /tftpboot/etc/{node hex ip}

B<nodeset> only sets the next boot state, but does not reboot.

B<nodeset>  is  called  by rinstall and winstall and is also called by the
installation process remotely to set the boot state back to "boot".

=head1 B<Options>

=over 7

=item B<boot>

Instruct network boot loader to be skipped, generally meaning boot to hard disk

=item B<install>

Prepare server for installing a node according to the table configuration.  This will
typically mean an unattended install file is created (i.e. kickstart or autoyast), 
install resources will be verified in tftp and the bulk transfer method (http, ftp, or nfs for example), and the boot loader configuration file will be written.

=item B<stat>

Display the current boot loader config file description for the nodes requested

=item B<runcmd=bmcsetup>

This instructs the node to boot to the xCAT nbfs environment and proceed to configure BMC
for basic remote access.  This causes the IP, netmask, gateway, username, and password to be programmed according to the configuration table.

=item B<shell>

This instructs tho node to boot to the xCAT nbfs environment, and present a shell prompt on console.
The node will also be able to be sshed into and have utilities such as wget, tftp, scp, nfs, and cifs.  It will have storage drivers available for many common systems.

=item B<-h>|B<--help>

Print help.

=item B<-v>|B<--version>

Print version.

=head1 B<Files>

B<noderes> table -
xCAT  node  resources  file.   See  B<noderes(5)>  for  further
details.

B<nodetype> table -
xCAT node installation type file.  See B<nodetype(5)> for  fur-
ther  details.   This is used to determine the node installation
image type.

B<site> table -
xCAT main  configuration  file.   See  B<site(5)>  for  further
details.   This  is  used  to determine the location of the TFTP
root directory and the TFTP xCAT  subdirectory.   /tftpboot  and
/tftpboot/xcat is the default.

=head1 B<Examples>

B<nodeset> I<node5> I<install>

node5: install compute62-compute

Install node5 with the compute62 image using resources from the compute
resource group.
