Changing storage class for OI

Issue/Introduction

We need to change the storage class that provides the PVCs for the DOI installation on OpenShift.  What is the supported scenario for doing this action? 

Note that Dxi APP uses local NFS and doesn’t support backup with Nutanix CSI , OpenShift have two storage class ( block and dynamic file ) .

We need al the PVC to be created with nutanix-dynamic storage class or nutanix-volume, not to use NFS local.

Cause

Unsupported Setup.

Resolution

Only supported is NFS-based and LocalStorage PVs+PVCs. If "createPv=true", then all PVs will be created during installation (cluster-admin scenario).

If "createPv=false" (namespace-admin or some other reasons not to create PVs during installation), then all required PVs must be created before installation.

We have dxi-generate-pvs.sh in the tools folder to help with generating yaml files with all required PVs. In either  of these scenarios, there is no need to change the StorageClass.
