Disabling CIFS for the entire storage system

Effect of storage system reboot on CIFS

The disabling of CIFS service is not persistent across reboots. If you reboot the storage system after disabling CIFS service, Data ONTAP automatically restarts CIFS.

After you disable CIFS for the entire storage system, most cifs commands become unavailable. The cifs commands you can still use with CIFS disabled are:

cifs prefdc
cifs restart
cifs setup
cifs testdc

Disabling CIFS service for the entire storage system

To disable CIFS service, complete the following step.

Step	Action
1	Enter the following command to disable CIFS service: *cifs terminate [-t time]* time is the number of minutes before the storage system disconnects all clients and terminates CIFS service. Entering 0 makes the command take effect immediately. Note If you enter the `cifs terminate` command without an argument and Data ONTAP detects an open file with any client, Data ONTAP prompts you for the number of minutes it should wait before it disconnects the client. Example cifs terminate -t 5 Result Data ONTAP sends a message to all connected clients, notifying the users of the impending disconnection. Five minutes after you enter the command, all clients are disconnected and the storage system stops providing CIFS service.
