Can Ontap CIFS clients survive a LIF migrate?
Applies to
- Data ONTAP 8
- ONTAP 9
- CIFS/SMB
Answer
Yes, LIF migration is non-disruptive for SMB 2.0 and later.
- SMB 2.0 and 2.1, the use of durable file handles allows the session to reconnect without any impact to the application.
- SMB 3.0 and 3.1, will have a persistent open state that facilitates the non-disruptive behavior.
- However, durable/persistent file handles are exclusive to a single-file open.
- Non-disruptive behavior might be affected when multiple users are accessing the same file.
