Checking for Local Storage Operator deployments

IBM Storage Fusion Data Foundation clusters with Local Storage Operator are deployed using local storage devices. To find out if your existing cluster with Fusion Data Foundation was deployed using local storage devices, use the following procedure:

Before you begin

Fusion Data Foundation is installed and running in the openshift-storage namespace.

About this task

By checking the storage class associated with your Fusion Data Foundation cluster’s persistent volume claims (PVCs), you can tell if your cluster was deployed using local storage devices.

Procedure

Check the storage class associated with Fusion Data Foundation cluster’s PVCs with the following command:
```
oc get pvc -n openshift-storage
```

Check the output.

For clusters with Local Storage Operator, the PVCs associated with ocs-deviceset use the storage class localblock. The output looks similar to the following:
