CIFS sessions must be terminated BEFORE UPGRADE, unless they are "Continuously available CIFS shares". Yes, there will be downtime for SMB/CIFS users. When you stop CIFS or terminate CIFS sessions, users will be disconnected.

Just go to this thread, and follow the steps given by - robinpeter

What would be the best approach to terminate the CIFS sessions before proceeding with the Data ONTAP upgrade. After upgrade can user access the data ?

Kindly recommend some commands to gracefully shutdown all CIFS session .

Check out the below KB for how to close CIFS sessions from the CLI.

https://kb.netapp.com/Advice_and_Troubleshooting/Data_Storage_Software/ONTAP_OS/How_to_terminate_a_CIFS_sessions_in_ONTAP_9_for_specific_Windows_users

If you terminate the CIFS session from the client, this would work as well, but doing via CLI is likely faster and easier.

Can we close all session from SVM as below : (gracefully) for 9.1 ONTAP) have more than 15 entries sometimes

::> cifs session close -node * -vserver vServer-01

Do we need to do any other configuration after upgrade from system manger for CIFS?

Yes that would work.

No, sessions will be automatically reestablished by the client as needed. Nothing else is required from NetApp side in regards to CIFS connections. Once the upgrade is complete I would be sure to check that all LIFs are "home" on their home node, however.
