Understanding zone failure

In this section, zone failure is considered as a failure where all Red Hat OpenShift Container Platform, master and worker nodes in a zone are no longer communicating with the resources in the second data zone (for example, powered down nodes). If communication between the data zones is still partially working (intermittently up or down), the cluster, storage, and network admins should disconnect the communication path between the data zones for recovery to succeed.

Important: Before installing the sample application, power off the OpenShift Container Platform nodes (at least the nodes with Fusion Data Foundation devices) to test the failure of a data zone to validate that your file-uploader application is available, and you can upload new files.
