Does enabling SMB2 on a NetApp filer require a cifs restart?

Question

I would like to enable SMB2 on a FAS 2050 running Data ONTAP 7.3.2 as by default it is disabled.

I have discovered that to enable SMB2 the following option must be set:

options cifs.smb2.enable on

Does this require a restart of cifs to take affect or just does it start working magically? Also will this change persist across a reboot?

Update: As per James post below the following setting allows the filer to use SMB2 when talking to other servers.

options cifs.smb2.client.enable on

Solution

Check na_options.

http://filer/na_admin/man/man1/na_options.1.html

cifs.smb2.enable This option enables SMB 2.0 support on the Filer. When this option is enabled, the Filer uses SMB 2.0 with a Windows client, if the client supports SMB 2.0. When this option is disabled, the Filer will not accept any new SMB 2.0 sessions; existing sessions are not terminated.

Default: off

Effective: Immediately

Persistence: Remains in effect across system reboots

cifs.smb2.client.enable This option enables SMB 2.0 client capability on the Filer. When this option is enabled, Filer-initiated connections to Windows servers use the SMB 2.0 protocol. If the Windows server does not support the SMB 2.0 protocol, the Filer uses SMB 1.0. If a session was established over SMB 2.0 and then this option is disabled, existing sessions are not terminated. The Filer continues to use SMB 2.0 for the existing sessions; new sessions do not use SMB 2.0.

Default: off

Effective: Immediately

Persistence: Remains in effect across system reboots
