To establish a connection between the vCenter Server and a storage provider, you must register the storage provider. Make sure to register a separate storage provider for each host in the cluster.


If you use Virtual SAN, the storage providers for Virtual SAN are registered and appear on the list of storage providers automatically. See View Virtual SAN Storage Providers. If for troubleshooting purposes you need to remove or unregister the Virtual SAN storage providers, you should remove the hosts for the storage providers and add the hosts back to the Virtual SAN cluster. Make sure at least one storage provider is in active state. Virtual SAN does not support manual registration of storage providers.


Verify that the storage provider component is installed on the storage side and obtain its credentials from your storage administrator.


  1. Browse to the vCenter Server in the vSphere Web Client navigator.
  2. Click the Manage tab, and click Storage Providers.
  3. Click the Register a new storage provider icon.
  4. Type connection information for the storage provider, including the name, URL, and credentials.
  5. (Optional) To direct the vCenter Server to the storage provider certificate, select the Use Storage Provider Certificate option and specify the certificate's location.

    If you do not select this option, a thumbprint of the certificate is displayed. You can check the thumbprint and approve it.

    This step is not valid for Virtual SAN and is optional for all other types of storage providers.

  6. Click OK to complete the registration.


The vCenter Server has registered the storage provider and established a secure SSL connection with it.
