 - Verify the `karavictl` binary is available.
 - Verify the appropriate Secret exists in the CSI driver namespace.

 7. (Optional) The following steps can be performed to enable Karavi Observability for PowerFlex/PowerScale/PowerMax to use an existing instance of Karavi Authorization for accessing the REST API for the given storage systems.
 You need to provide your own configurations. A sample values.yaml file is located [here](https://github.com/dell/helm-charts/blob/main/charts/karavi-observability/values.yaml).
 
 In your own configuration values.yaml, you need to enable PowerFlex/PowerScale/PowerMax Authorization, and provide the location of the sidecar-proxy Docker image and URL of the Karavi Authorization proxyHost address.
