+By default, the `domainUID` is left empty in the inputs file, which means the generated PV and PVC will not be associated with a particular domain, but can be shared by multiple domain resources in the same Kubernetes namespaces as the PV and PVC. If the PV/PVC is being shared across domains, then, as a best practice, you should specify a unique `baseName`.
 
 For the use cases where dedicated PV and PVC are desired for a particular domain, the `domainUID` needs to be set in the `create-pv-pvc-inputs.yaml` file. The presence of a non-empty `domainUID` in the inputs file will cause the generated PV and PVC to be associated with the specified `domainUID`. The association includes that the names of the generated YAML files and the Kubernetes PV and PVC objects are decorated with the `domainUID`, and the PV and PVC objects are also labeled with the `domainUID`.

+* **Managed Coherence Servers safe shutdown**.
+
+    If the domain is configured to use a Coherence cluster, then you will need to increase the Kubernetes graceful timeout value.
+    When a server is shut down, Coherence needs time to recover partitions and rebalance the cluster before it is safe to shut down a second server.
+    Using the Kubernetes graceful termination feature, the operator will automatically wait until the Coherence HAStatus MBean attribute
+    indicates that it is safe to shut down the server.  However, after the graceful termination timeout expires, the pod will be deleted regardless.
+    Therefore, it is important to set the domain YAML `timeoutSeconds` to a large enough value to prevent the server from shutting down before
+    Coherence is safe. Furthermore, if the operator is not able to access the Coherence MBean, then the server will not be shut down
+    until the domain `timeoutSeconds` expires.  To minimize any possibility of cache data loss, you should increase the `timeoutSeconds`
+    value to a large number, for example, 15 minutes.
