Install xCAT

On the VCL management node:

Download the xCAT yum repository files

wget -N -P /etc/yum.repos.d http://sourceforge.net/projects/xcat/files/yum/xcat-dep/rh6/x86_64/xCAT-dep.repo

wget -N -P /etc/yum.repos.d http://sourceforge.net/projects/xcat/files/yum/2.8/xcat-core/xCAT-core.repo

Install xCAT

yum clean all

yum install -y xCAT

Configure the xCAT site table

chtab key=master site.value=<management node private IP address>

chtab key=nameservers site.value=<management node private IP address>

chtab key=forwarders site.value=<DNS server address>

chtab key=dhcpinterfaces site.value=<management node private NIC>

chtab key=domain site.value=vcl.local

Configure the xCAT passwd table

chtab key=cmm passwd.username=<AMM SNMPv3 username> passwd.password=<AMM SNMPv3 password>

chtab key=system passwd.username=root passwd.password=<installed node root password>

Define the BladeCenter chassis Advanced Management Module (or Flex Chassis Management Module)

nodeadd <AMM name> groups=amm,all

chdef -t group amm mgt=blade

chdef -t group amm mpa=<AMM name> ip=<AMM IP address>

chtab mpa=<AMM name> mpa.username=<AMM SNMPv3 username> mpa.password=<AMM SNMPv3 password>

Define the blades

nodeadd vclh3-7-vclh3-8 groups=all,blade,compute

chtab mpa=bch3 mpa.username=<AMM SNMPv3 username> mpa.password=<AMM SNMPv3 password>

for i in {7..8} ; do chtab node=vclh3-$i mp.mpa=bch3 mp.id=$i ; done

Retrieve the blade MAC addresses

getmacs blade -i $NODE_MGT_NIC

Configure the xCAT networks table

chtab netname=142_104_128_0-255_255_252_0 networks.disable=1

chtab netname=172_22_0_0-255_255_255_0 networks.disable=1

Configure DHCP

makedhcp -n

chkconfig dhcpd on

service dhcpd start

makedhcp /vcl-n.*

ddns-update-style none;

Configuring DNS

rndc-confgen -a -r /dev/urandom

makedns
