Doc Text:
Previously, upgrading to Red Hat Enterprise Linux 7.6 introduced a new version of `dmidecode` that returns lower case system UUIDs instead of upper case. As a result, per-node hieradata customization might break for systems that rely on UUIDs. With this update, per-node customizations can use upper or lower case UUIDs. It is recommended to use lower case UUIDs.

Description Alex Schultz 2019-02-19 20:17:15 UTC 
+++ This bug was initially created as a clone of Bug #1678893 +++

This bug was initially created as a copy of Bug #1678346

I am copying this bug because: 

This affects all versions OSP15 and below for per-node hiera customization for users who have upgraded or deployed with RHEL7.5 and used an uppercase system uuid for per-node hieradata customization or os-net-config mappings.


Description of problem:

This has been fixed for osp13+
https://bugzilla.redhat.com/show_bug.cgi?id=1668774
https://bugzilla.redhat.com/show_bug.cgi?id=1654449

OSP 10 needs a similar fix to assist where environments are being patched and run into issues when dmidecode is updated to >= 3.1.

Hi,
Any idea how can I test this?
I've deployed undercloud manually and tried to change uuid of controller to upper case. When defining it again, the uuid automatically converted to lower case.
Comment 6 Alex Schultz 2019-03-25 13:50:23 UTC 
The patch here is that when you use the the uppercase UUID in the yaml to define custom hieradata that is makes it to the disk in /etc/puppet/hieradata and the value makes it to the correct configuration file.  So if the uuid is 57076f3c-3564-4d22-8004-7105995a9fd1, you specify 57076F3C-3564-4D22-8004-7105995A9FD1 and set an override and it makes it the correct configuration file.
Comment 7 Sasha Smolyak 2019-04-15 12:16:45 UTC 
I understand the idea of patch. I don't understand where to define it. I don't define uuid manually usually. What should I add to deployment in order to see the change? I understand that it needs to be in upper case, I don't understand at which step and where I can change it. As I mentioned previously, I've tried to change it post-deployment, but the operation system changed it back automatically before I could use it anywhere

Sanya, please look https://docs.openstack.org/tripleo-docs/latest/install/advanced_deployment/node_specific_hieradata.html
Comment 9 Sasha Smolyak 2019-04-17 09:23:31 UTC 
Verified.
Changed uuid to upper cases prior to overcloud deployment. The deployment passed, the uuid was correct.
Comment 10 Lon Hohberger 2019-04-17 10:39:32 UTC 
According to our records, this should be resolved by openstack-tripleo-heat-templates-8.2.0-6.2.el7ost.  This build is available now.
