On a CentOS7 system 

[hamzy@oscloud5 ~]$ lsb_release -a
LSB Version:    :core-4.1-amd64:core-4.1-noarch
Distributor ID: CentOS
Description:    CentOS Linux release 7.3.1611 (Core) 
Release:        7.3.1611
Codename:       Core
[stack@oscloud5 ~]$ uname -a
Linux oscloud5.stglabs.ibm.com 3.10.0-514.16.1.el7.x86_64 #1 SMP Wed Apr 12 15:04:24 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

Unfortunately, it seems that Environment setup for baremetal environment does not explain how to install the undercloud. There are three machines in this scenario:

arch use portname1 MAC1 IP1 portname2 MAC2 IP2
x86_64 undercloud eno2 6c:ae:8b:29:2a:02 9.114.219.30 eno4 6c:ae:8b:29:2a:04 9.114.118.98

So, following Undercloud installation, I perform the following: 

[hamzy@oscloud5 ~]$ sudo useradd stack
[hamzy@oscloud5 ~]$ sudo passwd stack
[hamzy@oscloud5 ~]$ echo "stack ALL=(root) NOPASSWD:ALL" | sudo tee -a /etc/sudoers.d/stack

        {

            "pm_addr":"9.114.118.155"
        }
    ]
}
__EOF__

I transfer over the built ppc64le overcloud images: 

(OCB=$(dig @192.168.122.1 -4 +short Overcloud.virbr0); UC=9.114.118.98; ssh-keygen -f ~/.ssh/known_hosts -R ${UC}; ssh-keyscan ${UC} >> ~/.ssh/known_hosts; scp -3 hamzy@${OCB}:~/ironic-python-agent.initramfs stack@${UC}:~/ppc64le-ironic-python-agent.initramfs; scp -3 hamzy@${OCB}:~/ironic-python-agent.kernel stack@${UC}:~/ppc64le-ironic-python-agent.kernel; scp -3 hamzy@${OCB}:~/overcloud-full.qcow2 stack@${UC}:~/ppc64le-overcloud-full.qcow2; scp -3 hamzy@${OCB}:~/overcloud-full.initrd stack@${UC}:~/ppc64le-overcloud-full.initrd; scp -3 hamzy@${OCB}:~/overcloud-full.kernel stack@${UC}:~/ppc64le-overcloud-full.kernel)

I then transfer over the built x86_64 overcloud images: 

[stack@oscloud5 ~]$ wget --quiet -O - https://images.rdoproject.org/pike/rdo_trunk/d558d6173970736fde63526da6824d391ada6042_89d45961/ironic-python-agent.tar | tar xvf -

I then modify undercloud.conf as follows:

And install the undercloud: 

[stack@oscloud5 ~]$ time openstack undercloud install 2>&1 | tee output.undercloud.install
...
Undercloud install complete.

Ironic needs some different settings to be able to support PXE for ppc64le:

Find out what version of rpms that you are using. Unfortunately, the patches do not apply cleanly for every release. Look for the short git commit hash. 

[stack@oscloud5 ~]$ rpm -qf /usr/lib/python2.7/site-packages/tripleo_common/actions/baremetal.py
openstack-tripleo-common-8.1.1-0.20171104061839.9c4e6a0.el7.centos.noarch
[stack@oscloud5 ~]$ rpm -qf /usr/lib/python2.7/site-packages/tripleoclient/v1/overcloud_node.py
python-tripleoclient-8.0.1-0.20171107051030.61ddfc3.el7.centos.noarch

The short git commit hash for tripleo-common would be 9c4e6a0 and for python-tripleoclient would be 61ddfc3.el7. Prepare your system for some patches... 

[stack@oscloud5 ~]$ (git config --global user.name "Mark Hamzy"; git config --global user.email hamzy@us.ibm.com; git clone git://git.openstack.org/openstack/tripleo-common; git clone git://git.openstack.org/openstack/python-tripleoclient)

There is a bug for needing the userid for machines using ipmi that needs to be patched around. There are fixes to tripleo-common for hard coded ironic-python-agent and overcloud names. 

[stack@oscloud5 ~]$ (cd tripleo-common/; curl --silent -o - https://hamzy.fedorapeople.org/TripleO-multi-arch/05.bb2b96e/0001-fix-usernameless-IPMI.patch | git am)

[stack@oscloud5 ~]$ (cd tripleo-common/; curl --silent -o - https://hamzy.fedorapeople.org/TripleO-multi-arch/05.bb2b96e/0001-fix_multi_arch-tripleo-common.patch | git am)
Applying: fix_multi_arch tripleo-common

There are fixes to python-tripleoclient for hard coded ironic-python-agent and overcloud names. 

[stack@oscloud5 ~]$ (cd python-tripleoclient/; curl --silent -o - https://hamzy.fedorapeople.org/TripleO-multi-arch/05.cc5fee3/0001-fix_multi_arch-python-tripleoclient.patch | git am)
Applying: fix_multi_arch python-tripleoclient

After the patches have been applied, they need to be installed: 

[stack@oscloud5 ~]$ (cd python-tripleoclient/; sudo python setup.py install --force) 2>&1 | tee output.install.python-tripleoclient
[stack@oscloud5 ~]$ (cd tripleo-common/; sudo python setup.py install --force) 2>&1 | tee output.install.tripleo-common

Once everything has been patched, update the workbooks and restart all of the necessary services. 

[stack@oscloud5 ~]$ (cd /usr/share/openstack-tripleo-common/; openstack workbook update workbooks/validations.yaml; openstack workbook update workbooks/baremetal.yaml)
[stack@oscloud5 ~]$ sudo mistral-db-manage --config-file /etc/mistral/mistral.conf --debug populate
[stack@oscloud5 ~]$ (for SERVICE in openstack-mistral-api.service openstack-mistral-engine.service openstack-mistral-executor.service; do sudo systemctl restart ${SERVICE}; done)
[stack@oscloud5 ~]$ for I in openstack-ironic-conductor.service openstack-ironic-inspector.service openstack-ironic-inspector-dnsmasq.service; do sudo systemctl restart ${I}; done

I then go through the process of uploading images for the overcloud: 

[stack@oscloud5 ~]$ source stackrc
(undercloud) [stack@oscloud5 ~]$ AGENT_NAME=x86_64-ironic-python-agent time openstack overcloud image upload --os-image-name x86_64-overcloud-full.qcow2

...

Now import the baremetal nodes and assign them profiles. 

(undercloud) [stack@oscloud5 ~]$ time openstack overcloud node import --provide instackenv.json 2>&1 | tee output.overcloud.node.import
