Rebooting a storage system can affect the state of a protocol or a vFiler unit located in the storage system. If you allow or disallow a protocol on a vFiler unit, the allowed or disallowed protocol persists across reboots.
If you want to allow a protocol again after a reboot, you must reenable the protocol. For example, if you disallow NFS for a vFiler unit and then reboot the storage system, NFS remains disallowed for the vFiler unit after the reboot.
When you stop a vFiler unit and then reboot the storage system, the stopped vFiler unit starts running again after the reboot.
