>Note: If you continue to use the old storage classes, you may not be able to take advantage of any new storage class parameter supported by the driver.

**Steps to create secondary storage class:**

There are samples storage class yaml files available under `samples/storageclass`. These can be copied and modified as needed.

1. Copy the `storageclass.yaml` to `storageclass_2.yaml` ( This is just an example, you can rename to file you require. )

2. Edit the `storageclass_2.yaml` yaml file and update following parameters:
- Update the `name` parameter to you require
````yaml
metadata:
name: isilon-new
````
- Cluster name of 2nd array looks like this in the secret file.( Under `/samples/secret/secret.yaml`)
````yaml
- clusterName: "cluster2"
username: "user name"
password: "Password"
endpoint: "10.X.X.X"
endpointPort: "8080

- Use same clusterName ↑ in the `storageclass_2.yaml`
````yaml
# Optional: true
ClusterName: "cluster2"
- *Note*: These are two essential parameters that you need to change in the "storageclass_2.yaml" file and other parameters that you change as required.
3. Save the `storageclass_2.yaml` file
4. Create your 2nd storage class by using `kubectl`:
````bash
kubectl create -f <path_to_storageclass_2_file>
````
5. Use newly created storage class `isilon-new` for volumes to spin up on `cluster2`

PVC example
````yaml
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: test-pvc
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 5Gi
storageClassName: isilon-new
````

## Volume Snapshot Class

Starting CSI PowerScale v1.6, `dell-csi-helm-installer` will not create any Volume Snapshot Class during the driver installation. Sample volume snapshot class manifests are available at `samples/volumesnapshotclass/`. Use these sample manifests to create a volumesnapshotclass for creating volume snapshots; uncomment/ update the manifests as per the requirements.
