Using existing vCenter SPBM policy . If you run Kubernetes or OpenShift on bare-metal, your cluster nodes will be also treated as personal resource. Manually delete the associated storage asset, or if you want to reuse the same storage asset, create a new PersistentVolume with the storage asset definition. Kubernetes, as of today, however, doesn’t treat the storage like a native resource on par with CPU and Memory - which makes it a little hard to make Kubernetes work out of the box to make effective use of the storage attached to the nodes.

Kubernetes allows users to automatically mount a storage system of choice, such as local storage, public cloud providers, and more. The local storage feature in Kubernetes takes over and handles scheduling, by StorageClass for the different underlying disk types. You still need to provide the underlying storage system.
