Version-Release number of selected component (if applicable):
openstack-tripleo-heat-templates-9.0.0-0.20181001174822.90afd18.0rc2.el7ost.noarch
ansible-role-redhat-subscription-1.0.1-1.el7ost.noarch

How reproducible:
100%

Steps to Reproduce:
1. Deploy overcloud with nodes registered to satellite
2. Assert successful deployment
3. Run overcloud deploy command for a second time

Actual results:
Failure during TASK [redhat-subscription : Manage Red Hat subscription]

Expected results:
No failures.

Additional info:
Running the command manually on the overcloud nodes:
