Thank you, that filled in a big part of the puzzle!

I am still confused how to get bmcdiscover to add the information to the
existing node, instead of creating a new one.

bmcdiscover seems to generate a new second node, and I'm not sure how to
correlate that to the existing one. The page you pointed me to seems to
suggest this is a manual process?


node-dell-poweredge-r230-7q3z7m2:
    objtype=node
    groups=all
    bmc=192.168.101.201
    cons=ipmi
    mgt=ipmi
    mtm=DELL:PowerEdge R230
    serial=7Q3Z7M2
    bmcusername=root
    bmcpassword=calvin

And this is the one I already have predefined.

Object name: cn-001
    arch=x86_64
    cons=ipmi
    groups=ipmi,all,all,compute
    installnic=mac
    ip=192.168.101.3
    mac=50:9A:4C:74:58:0F
    mgt=ipmi
    netboot=xnba
    nichostnamesuffixes.em1=-comp
    nichostnamesuffixes.em2=-mgt
    nicips.em1=192.168.100.3
    nicips.em2=192.168.101.3
    os=rhels7.4
    postbootscripts=otherpkgs,confignics
    postscripts=syslog,remoteshell,syncfiles,setupntp
    primarynic=mac
    profile=hpccn
    provmethod=rhels7.4-x86_64-netboot-hpccn
    updatestatus=failed
    updatestatustime=02-20-2018 16:26:47
