Unregister storage providers that you do not need.
You cannot manually unregister storage providers supplied by VMware, such as Virtual SAN storage providers.
- Browse to vCenter Server in the vSphere Web Client navigator.
- Click the Manage tab, and click Storage Providers.
- From the list of storage providers, select the one you want to unregister and click the Unregister the storage provider icon.
vCenter Server terminates the connection and removes the storage provider from its configuration.
