Describe the issue: The section "3.2. Creating an OpenShift Data Foundation Cluster for external IBM FlashSystem storage" in the External Mode doc[1] is not complete in the sense that it doesn't give all the needed details for anyone to understand what is expected from this deployment. [1] https://access.redhat.com/documentation/en-us/red_hat_openshift_data_foundation/4.13/html/deploying_openshift_data_foundation_in_external_mode/deploy-openshift-data-foundation-using-ibm-flashsystem#creating-an-openshift-data-foundation-cluster-for-ibm-flashsystem-storage_ibmfs-external Describe the task you were trying to accomplish: - I was trying to understand the difference wrt to External ceph and Internal mode deployment I was trying to understand what all pods will be available after the deployment. Suggestions for improvement: - Add some details at the beginning to help the reader understand what external IBM flashsystem deployment means and how it works. - In the deployment procedure section, point 4 says -------------------------------- i. Enter a name for the storage class. When creating block storage persistent volumes, select the storage class <storage_class_name> for best performance. The storage class allows direct I/O path to the FlashSystem. -------------------------------- Not sure if "<storage_class_name>" needs to be replaced with the correct name. As a reader, I am expecting that but I am not sure what is technically correct here. - The list of pods in the section "Verification Steps" is not complete. I expect a lot many more pods to be created after storgesystem creation done in the previous step.
