Hello all,
With SMB3 support available on Windows OS releases Server 2012, WIN8 & later persistent handle support has become available. Since ONTAP9 continuously available (CA) shares have also become an option. There is however a caveat in TR 4100 (https://www.netapp.com/us/media/tr-4100.pdf) which states
"ONTAP 9 does not support persistent handles for use cases other than Microsoft Hyper-V over SMB and SQL Server over SMB".
We are curious about this statement. We have created standard CIFS File Shares with CA enabled and successfully performed multiple takeover and givebacks without disruption to CIFS activity. Testing the same shares with the CA option disabled was, as expected, disruptive. Does anyone understand why standard windows shares with CA enabled are not officially supported and\ or have any experience of using them in a production environment?
best regards, D
