Can I proceed with ONTAP upgrade when Hyper-V is in use, if the validation report advises "Stop all unprotected CIFS workload"?
Applies to
- ONTAP 9
- Microsoft Hyper-V
- SMB/CIFS
Answer
- Hyper-V over SMB support nondisruptive operations (NDOs).
- With a Hyper-V over SMB solution, the application servers and the contained virtual machines or databases remain online and provide continuous availability during the ONTAP upgrade.
- Continuously available CIFS shares (CA), accessed by Hyper-V Server clients using the SMB 3.0 protocol, do not need to be terminated before upgrading or downgrading.
