• Launch manual discovery of new nodes BMC:

  $ bmcdiscover -t -z --range 192.168.1.121-132 > bmcdiscover.nodes
  

• Adjust hostnames inside generated file bmcdiscover.nodes

• Create objects for BMC:

  $ cat bmcdiscover.nodes | mkdef -z
  

  makeconservercf systemctl restart conserver

Automatic Discovery

• Create discovery network:

  $ makenetworks
  $ tabedit networks
  "10_10_10_0-255_255_255_0","10.10.10.0","255.255.255.0","enP3p9s0f0","<xcatmaster>",,"10.10.10.1",,,,"10.10.10.2-10.10.10.100",,,,,,,,
  $ chdef -t 10_10_10_0-255_255_255_0 dynamicrange=”10.10.10.2-10.10.10.100”
  $ makedhcp -a
  $ systemctl restart dhcpd

  $ mknb ppc64
  Creating genesis.fs.ppc64.gz in /tftpboot/xcat
  

• Launch Sequential Discovery:

  $ nodediscoverls -t all
  $ nodediscoverstart noderange=”host[01-12]”
  $ nodediscoverstatus -V noderange=host[01-12]
  Sequential discovery is running.
  $ rpower host01-adm on
  $ nodediscoverls -t all
  $ nodediscover stop
