IBM block storage --- CSI driver -- support for Hosted Control Plane (HCP)

See this idea on ideas.ibm.com

For this SAN discussion we are focused on RedHat Open Shift (RHOS) environment.
Here we will enable the Virtualization feature of RHOS soon.

Our challenge: Attach SAN storage (IBM Storage Virtualize) for stateful data.
We have bare-metal worker nodes where we want to attach the SAN storage to.
And to add: We have a hosted plane where one central plane controlls activties for other RHOS systems.

Our request: IBM CSI driver for SAN has to support this configuration. By the way, things like multipathing should work in this environment.

    For clarification:

    We support both virtual hosts and bare metal (physical hosts) as part of standalone configurations only: https://docs.openshift.com/container-platform/4.14/hosted_control_planes/index.html

    We have not tested HCP. We will evaluate this request.

    Thank you for submitting this Idea. I have spoken to the team and this configuration should already be supported. Have you run into any specific issues preventing you from deploying CSI driver in this environment?


    Thanks,
