Which role/persona is responsible for configuring storage for Cloud Pak for Business Automation capabilities?

The Cloud Pak System Administrator is responsible for the deployment, configuration, and management of the IBM Cloud Pak for Business Automation instance. A key part of this responsibility is creating and customizing the Custom Resource (CR) file. This file specifies the configuration details for the deployment, including which pre-existing storage classes to use for the various capabilities' Persistent Volume Claims (PVCs), storage sizes, and access modes. While the Cluster Administrator makes storage available at the cluster level, the Cloud Pak System Administrator configures its specific use for the Cloud Pak's components.

B. Developer: A developer's role is to build and deploy applications that run on the Cloud Pak platform, not to configure the platform's underlying storage infrastructure.
C. Cluster Administrator: The Cluster Administrator is responsible for preparing the underlying OpenShift/Kubernetes cluster, which includes creating and managing the StorageClasses, but not for configuring how the specific Cloud Pak deployment consumes that storage.
D. Systems Integrator: This is a job function or a role in a project team, not a defined operational persona with specific permissions within the Cloud Pak's Role-Based Access Control (RBAC) model.

1. IBM Cloud Pak for Business Automation 23.0.2 Documentation

"Roles and permissions for a production deployment": This document outlines the distinct responsibilities. It states the Cluster administrator is responsible for "Storage preparation

" which involves setting up the cluster's storage classes. It then defines the Cloud Pak administrator as the one responsible to "Create the custom resource to install an instance of the Cloud Pak." The custom resource is where storage is configured for the specific capabilities.

"Creating the custom resource": The documentation shows that parameters like scdynamicstorageclassname and storage settings for each component are defined within the Custom Resource YAML file. The creation and application of this file is the responsibility of the Cloud Pak administrator

who is synonymous with the Cloud Pak System Administrator role in this context.

3. IBM Cloud Pak for Business Automation 23.0.2 Documentation

"Preparing storage": This section details the tasks for storage preparation. It explicitly mentions that the cluster administrator must create persistent volumes (PVs) and storage classes. The subsequent step

performed by the Cloud Pak administrator

is to use these prepared storage classes in the custom resource definition.
