For any discovered vCenters, you can enable or disable access for any ESXi host managed by the vCenter. After you associate a vCenter server configuration with a VMware datastore, the datastore is available to any ESXi hosts associated with the vCenter host configuration.
      The vCenter credentials are stored in the storage system.
      You need to have an active session with the array.
