Bug 1904169

Description of problem (please be detailed as possible and provide log
snippests):

Following the docs (https://access.redhat.com/documentation/en-us/red_hat_openshift_container_storage/4.5/html/deploying_openshift_container_storage_on_vmware_vsphere/deploy-using-local-storage-devices-vmware#installing-openshift-container-storage-operator-using-the-operator-hub_local-storage)

I have a 4.6.6 OCP cluster installed on vsphere 6.7. I also tried this with OCP 4.6.4. 
3 masters each with 4 cpu, 16GB mem, 120GB disk. 
3 workers each with 16 cpu, 48GB mem, 120GB disk

1. Added hard drives to each of the workers. 450GB each using SSD. 

2. Labeled worker nodes: oc label nodes <NodeNames> cluster.ocs.openshift.io/openshift-storage=''

3. Install OCS via operator. Version 4.5.2. Took defaults. openshift-storage ns not created yet. Checked box for cluster monitoring of the ns. Install successful.

4. Install local storage operator. Version 4.6.0-202011181111.p0. Took defaults. Did not create local-storage ns as docs say. Operator creates openshift-local-storage ns. Install successful.

*note docs say: The Local Storage Operator version must match the Red Hat OpenShift Container Platform version in order to have the Local Storage Operator fully supported with Red Hat OpenShift Container Storage. The Local Storage Operator does not get upgraded when Red Hat OpenShift Container Platform is upgraded.

So I should be able to use LSO 4.5, but it is not an option in the operator hub.

5. Found the storage devices (used DeamonSet):

6. Create service that uses local block storage in OCS
Internal mode: localblock storageclass is not presented.
Internal - attached devices: localblock storage class is present, but I get an error that says Minimum Node Requirement - The OCS Storage cluster require (sp) a minimum of 3 nodes for the initial deployment. Please choose a different stirage class or create a new volume set that matches the minimum node requirement. 

I've tried creating a new volume set, and that doesn't work either.
