ibm-block-csi-controller-sa	anyuid
ibm-block-csi-node-sa	privileged

Procedure

From Red Hat OpenShift Container Platform Home > Projects, click Create Project. In the Create Project dialog box, fill in a Project name (also referred to as namespace). Click Create to save.
From Operators > OperatorHub. Select the namespace from Projects: <namespace>, defined in step 1.
Search for IBM block storage CSI driver.
Select the Operator for IBM block storage CSI driver and click Install.
The Operator Subscription form appears.
Set the Installation Mode to the project namespace selected above, in step 2, under A specific namespace on the cluster.
(Optional): Set the Approval Strategy to Automatic.
Click Subscribe.
From Operators > Installed Operators, check the status of the Operator for IBM block storage CSI driver.
Wait until the Status is Up to date and then InstallSucceeded.

Note: While waiting for the Status to change from Up to date to InstallSucceeded, you can check the pod progress and readiness status from Workloads > Pods.
Once the operator installation progress has completed, click on the installed Operator for IBM block storage CSI driver.

Click Create Instance to create the IBM block storage CSI driver (IBMBlockCSI).

A yaml file appears in the web console. This can be left as-is, or edited as needed.
