Note that this is an issue with the protocol itself, rather than the storage. This happens across all vendors.

We have a TR that covers CIFS NDO scenarios.

Using anything but the newest version of SMB (which, as far as I know, is windows 2012 only), no. All LIF migrations and node HA failovers entail a reset of the CIFS sessions.

Hi all,

with cDOT is there a way to avoid that CIFS sessions fall during a takeover?

In 7 Mode when an NDU operation is performed CIFS must is interrupted and open CIFS sessions fall if not closed before.

Is there a way using failover groups of the data LIF to avoid this?

Regards,
