=head1 NAME

B<xcatsetup> - Prime the xCAT database using naming conventions specified in a config file.

=head1 SYNOPSIS

B<xcatsetup> [B<-s|--stanzas> I<stanza-list>] I<cluster-config-file>

B<xcatsetup> [B<-?> | B<-h> | B<--help> | B<-v> | B<--version>]

=head1 DESCRIPTION

The B<xcatsetup> command reads the specified config file that contains general information about the cluster being set up,
and naming conventions and IP addresses that you want to use.  It then defines the basic objects in the xCAT database
representing this cluster configuration.  The B<xcatsetup> command prepares the database for the step of discovering
the hardware that is connected to the service and cluster networks.  The typical steps of setting up a system p cluster are:

=over 3

=item *

Install the xCAT software on the management node

=item *

Create the cluster config file and run xcatsetup

=item *

Put hardware control passwords in the ppchcp or ppcdirect database table

=item *

Run the discovery commands (lsslp, mkhwconn, rspconfig) as described in the System P Hardware Management cookbook.

=item *

Configure and start the services using makehosts, makedns, makedhcp, mkconserver.cf, etc.

=item *

Create the images that should be installed or booted on the nodes

=item *

Run nodeset and rpower/rnetboot to boot up the nodes.

The B<xcatsetup> command is intended as a quick way to fill out the database for a cluster that has very regular
naming patterns.  The only thing it does is fill in database attributes.  If your cluster does not follow consistent
naming patterns, or has some other special configuration, you should define attribute values manually instead of using
B<xcatsetup>.  The cluster config file is meant to be an easy way to prime the database; it is not meant to be a
long living file that you update as the cluster changes.  If you do want to run xcatsetup again at a later time,
because, for example, you added a lot of nodes, you should put the total list of nodes in the config file, not just
the new ones.  This is because xcatsetup uses some regular expressions for groups (e.g. frame, cec, compute) that would
be calculated incorrectly if the config file told xcatsetup about only the new nodes.

Speaking of regular expressions, xcatsetup creates some pretty complicated regular expressions in the database.
These are useful because they keep most of the tables small, even for large clusters.  But if you want to
tweak them, they may be hard to understand.  If after running xcatsetup, you want to convert your database to
use individual rows for every node, you can do the following:

  lsdef -z all >tmp.stanza
  cat tmp.stanza | chdef -z

If you want to delete all of the nodes that xcatsetup created, and start over, use L<rmdef(1)|rmdef.1> and give it all of the ranges
specified in the config file.

=head2 Restrictions

=over 3

=item *

The B<xcatsetup> command has only been implemented and tested for system p servers so far.

=item *

Redundant BPAs and FSPs are not yet supported.

=item *

Hostname ranges must start with 1 (or 01, etc.).  I.e. use node01-node80, instead of node03-node83.

=head2 Configuration File

The B<config file> is organized in stanza format and supports the keywords in the sample file below.  Comment lines
begin with "#".  Stanzas can be ommitted if you do not want to define that type of object.
The only hostname formats supported are those in this sample file, although you can change the base
text and the numbers.  For example, hmc1-hmc3 could be changed to hwmgmt01-hwmgmt12.
The hostnames specified must sort correctly.  I.e. use node01-node80, instead of node1-node80.

  xcat-site:
   domain = cluster.com
   # currently only direct fsp control is supported
   use-direct-fsp-control = 1
   # ISR network topology.  For example, one of the following: 128D, 64D, 32D, 16D, 8D, 4D, 2D, 1D
   topology = 32D

  xcat-hmcs:
   hostname-range = hmc1-hmc3
   starting-ip = 10.201.1.1

  xcat-frames:
   # these are the connections to the BPCs
   hostname-range = bpc1-bpc6
   starting-ip = 10.202.1.1
   num-frames-per-hmc = 2
   # this lists which serial numbers go with which frame numbers
   vpd-file = vpd.stanza

  xcat-cecs:
   # these are the connections to the FSPs.  Either form of hostname is supported.
   #hostname-range = cec01-cec60
   hostname-range = f[1-6]c[01-10]
   starting-ip = 10.203.1.1
   # lists the HFI supernode numbers for each group of cecs in each frame
   supernode-list = supernodelist.txt

   num-service-nodes-per-bb = 2
   # which cecs within the bldg block that the SNs are located in
   cec-positions-in-bb = 1,20
   # this is for the ethernet NIC on each SN
   hostname-range = sn1-sn6
   starting-ip = 10.200.1.1

   # the IP addresses are starting IP addresses

   otherinterfaces = -hf1:10.21.1.1,-hf2:10.22.1.1,-hf3:10.23.1.1,-ml0:10.24.1.1

  xcat-compute-nodes:
   hostname-range = n001-n465
   starting-ip = 10.30.1.1
   aliases = -hf0
   # ml0 is for aix.  For linux, use bond0 instead.
   otherinterfaces = -hf1:10.31.1.1,-hf2:10.32.1.1,-hf3:10.33.1.1,-ml0:10.34.1.1

=head2 VPD File for Frames

The B<vpd-file> specifies the following vpd table attributes for the BPCs (frame power supplies):  node,
serial, mtm, side.  Use the same stanza format that accepted by the L<chdef(1)|chdef.1> command, as documented
in L<xcatstanzafile(5)|xcatstanzafile.5>.  The purpose of this file is to enable xCAT to match up BPCs found
through L<lsslp(1)|lsslp.1> discovery with the database objects created by B<xcatsetup>.  All of the BPCs
in the cluster must be specified (A-side only).

Here is a sample file:

  bpc01:
    objtype=node
    serial=99200G1
    mtm=9A00-100
    side=A

  bpc02:
    objtype=node
    serial=99200D1
    mtm=9A00-100
    side=A

=head2 Supernode Numbers for CECs

The B<supernode-list> file lists what supernode numbers should be given to each CEC in each frame.
Here is a sample file:

  bpc01: 0, 1, 16
  bpc02: 17, 32
  bpc03: 33, 48, 49
  bpc04: 64 , 65, 80
  bpc05: 81, 96
  bpc06: 97(1), 112(1), 113(1)

The name before the colon is the node name of the frame BPC.  The numbers after the colon are the supernode numbers
to assign to the groups of CECs in that frame from bottom to top.  Each supernode contains 4 CECs, unless it is immediately
followed by "(#)", in which case the number in parenthesis indicates how many CECs are in this supernode.

=head2 Database Attributes Written

The following lists which database attributes are filled in as a result of each stanza.  Note that depending on the values
in the stanza, some attributes might not be filled in.

=head1 OPTIONS

=over 10

=item B<-s|--stanzas> I<stanza-list>

A comma-separated list of stanza names that B<xcatsetup> should process in the configuration file.  If not specified, it will process
all the stanzas that start with 'xcat' and some other stanzas that give xCAT hints about how to set up the HPC products.

This option should only be specified if you have already run B<xcatsetup> earlier with the stanzas that occur before this in the
configuration file.  Otherwise, objects will be created that refer back to other objects that do not exist in the database.

=item B<-v|--version>

Command Version.
