=head1 NAME B - Prime the xCAT database using naming conventions specified in a config file. =head1 SYNOPSIS B [I] B [B<-?> | B<-h> | B<--help> | B<-v> | B<--version>] =head1 DESCRIPTION The B 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 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. =back The B 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. 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 Note: currently the B command has only been implemented and tested for system p servers. The B 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. Note that currently hostname ranges must have simple format, like the examples in this sample file. xcat-site: domain = cluster.com use-direct-fsp-control = 1 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 vpd-file = vpd.stanza xcat-cecs: # these are the connections to the FSPs hostname-range = cec01-cec60 starting-ip = 10.203.1.1 supernode-list = supernodelist.txt xcat-building-blocks: num-frames-per-bb = 2 num-cecs-per-bb = 20 xcat-lpars: num-lpars-per-cec = 8 num-service-nodes-per-bb = 2 # this is for the ethernet NIC on each SN service-node-hostname-range = sn1-sn6 service-node-starting-ip = 10.200.1.1 # this value is the same format as the hosts.otherinterfaces attribute except # the IP addresses are starting IP addresses service-node-otherinterfaces = -hf0:10.10.1.1,-hf1:10.11.1.1,-hf2:10.12.1.1,-hf3:10.13.1.1 num-storage-nodes-per-bb = 3 storage-node-hostname-range = stor01-stor09 storage-node-starting-ip = 10.20.1.1 storage-node-aliases = -hf0 storage-node-otherinterfaces = -hf1:10.21.1.1,-hf2:10.22.1.1,-hf3:10.23.1.1 num-compute-nodes-per-bb = 155 compute-node-hostname-range = n001-n465 compute-node-starting-ip = 10.30.1.1 compute-node-aliases = -hf0 # ml0 is for aix.

Use the same stanza format that accepted by the L command, as documented in L. 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 The B 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. 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. =over 15 =item B site table: domain, nameservers =item B nodelist table: node, groups hosts table: node, ip ppc table: node, comments nodetype table: node, nodetype =item B nodelist table: node, groups hosts table: node, ip ppc table: node, id, hcp nodetype table: node, nodetype nodehm table: node, mgt vpd table: node, serial, mtm, side =item B nodelist table: node, groups hosts table: node, ip ppc table: node, supernode, hcp, id, parent nodetype table: node, nodetype nodehm table: node, mgt =item B site table: sharedtftp ppc table: node, parent (for frame) =item B nodelist table: node, groups hosts table: node, ip, hostnames, otherinterfaces ppc table: node, id, hcp, parent nodetype table: node, nodetype, arch nodehm table: node, mgt, cons noderes table: netboot servicenode table: node, nameserver, dhcpserver, tftpserver, nfsserver, conserver, monserver, ftpserver, nimserver, ipforward =back =head1 OPTIONS =over 10 =item B<-v|--version> Command Version. =item B<-?|-h|--help> Display usage message. =back =head1 RETURN VALUE 0 The command completed successfully. 1 An error has occurred. =head1 FILES /opt/xcat/sbin/xcatsetup =head1 SEE ALSO L, L, L, L, L, L
