# Known issues
Known issues in this release of Red Hat OpenShift Container Platform (OCP) on HPE SimpliVity:
- Disaster recovery for OpenShift Container Platform is broken for various deployments, including bare metal and vSphere. (BZ#1718436) 
- The playbooks make the master nodes non-schedulable. By default, the OCP 4.2 installer generates Kubernetes manifests which would make the master nodes schedulable in an attempt to support clusters with smaller footprints. However, a limitation with Kubernetes means router pods running on control plane machines will not be reachable by the ingress load balancer. The playbooks modify a manifest generated by the installer prior to running the actual installation in order to make the master nodes non-schedulable. 
- Ansible - 2.9.1has a known issues that causes the cluster deployment to fail. The tested and recommended version of Ansible is- 2.8.5. Versions newer than- 2.9.1may work but have not been tested.
