=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>] [B<--yesreallydeletenodes>] 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:

|
|
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 using L<mkdef(1)|mkdef.1>, 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
|
|
|
|
Many of the sections and attributes in the configuration file can be omitted, if you have a simple cluster, or if you want
|
|
to create just 1 or 2 of the object types at this time. See the section B<A Simpler Configuration File> for an example of this.
|
|
|
|
If you want to delete all of the nodes that xcatsetup created, and start over, use the B<--yesreallydeletenodes> option.

|
=over 3
|
|
|
|
=item *
|
|
|
|
The B<xcatsetup> command has only been implemented and tested for system p servers so far.

|

|
|
|
|
=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 shown 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.
|
|
This sample configuration file is for a 2 building block cluster.

|
=head2 VPD File for Frames
|
|
|
|
The B<vpd-file> specifies the following vpd table attributes for the frames: 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 frames found
|
|
through L<lsslp(1)|lsslp.1> discovery with the database objects created by B<xcatsetup>. All of the frames
|
|
in the cluster must be specified.
|
|
|
|
Here is a sample file:
|
|
|
|
frame1:
|
|
objtype=node
|
|
serial=99200A1
|
|
mtm=78AC-100
|
|
side=A
|
|
|
|
frame2:
|
|
objtype=node
|
|
serial=99200B1
|
|
mtm=78AC-100
|
|
side=A
|
|
|
|
frame3:
|
|
objtype=node
|
|
serial=99200C1
|
|
mtm=78AC-100
|
|
side=A
|
|
|
|
frame4:
|
|
objtype=node
|
|
serial=99200D1
|
|
mtm=78AC-100
|
|
side=A
|
|
|
|
frame5:
|
|
objtype=node
|
|
serial=99200E1
|
|
mtm=78AC-100
|
|
side=A
|
|
|
|
frame6:
|
|
objtype=node
|
|
serial=99200F1
|
|
mtm=78AC-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:
|
|
|
|
frame1: 0, 1, 16
|
|
frame2: 17, 32
|
|
frame3: 33, 48, 49
|
|
frame4: 64 , 65, 80
|
|
frame5: 81, 96
|
|
frame6: 97(1), 112(1), 113(1), 37(1), 55, 71
|
|
|
|
The name before the colon is the node name of the frame. 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 A Simpler Configuration File
|
|
|
|
This is an example of a simple cluster config file that just defines the frames and CECs for 2 frames, without specifying
|
|
VPD data or supernode numbers at this time.
|
|
|
|
xcat-site:
|
|
use-direct-fsp-control = 1
|
|
|
|
xcat-frames:
|
|
hostname-range = frame[1-2]
|
|
|
|
xcat-cecs:
|
|
hostname-range = cec[01-24]
|
|
num-cecs-per-frame = 12
|
|
|
|
=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.

|
=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.

|
Delete the nodes represented in the cluster config file, instead of creating them. This is useful if your first attempt with the cluster
|
|
config file wasn't quite right and you want to start over. But use this option with extreme caution, because it will potentially delete
|
|
a lot of nodes. If the only thing you have done so far in your database is add nodes by running B<xcatsetup>, then it is safe to use this
|
|
option to start over. If you have made other changes to your database, you should first back it up using L<dumpxCATdb(1)|dumpxCATdb.1> before
|
|
using this option.
