[Q] SMB3.0 connection to OneFS8.0

Question

Hello Experts, I'm having a trouble to establish SMB3.0 connection with OneFS8.0. This is for internal testing for SMB3.0 CA (Continuous Availability) in our lab. The client is windows server 2012 R2 and capable of smb3.0 whereas it looks the isilon shows only 1.5 as its dialect, which may cause their connection goes down as version 1.5. Any advise would be greatly appreciated if I may be missing something or which I should start find our more. --------------------------------------------------------------------- PS C:\> get-smbconnection ServerName          ShareName           UserName            Credential          Dialect             NumOpens ----------          ---------           --------            ----------          -------             -------- iq221.isidom1.local share1-CA           ISIDOM1\Administ...

Hi tezuky,

Do you have multichannel enabled on the Windows 2012 server? It is a requirement with Isilon and SMB 3.0. SMB 3.0 is supported on OneFS 8.0 and later in combination with Windows Server 2012 and later, so it sounds like you have all of the required software components, it is just a matter of adjusting the settings.

The 8.0 Web Admin Guide goes into some detail about what is required for multichannel. The client side settings start on page 196 but the SMB discussion starts on 194 here:https://support.emc.com/docu65068

Hi Sjones,

Thank you for the advise. As far as checked, for both the win 2012R2 client and isilon, smb multi-channel is enabled. But nothing appears by Get-SmbMultichannelConnection command below.

Hi tezuky,

Did you confirm that the NIC on the server meets the requirements laid out in the guide? Page 194: https://support.emc.com/docu65068

The only other thing on the cluster side that I have come across is that you need to have both interfaces from the NIC on the Isilon as a member of the SmartConnect pool.
So if you are using a 10 gig link for example, you would need to have 10-gige-1 and 10-gige-2 as active members in the pool.

Beyond that, you may consider contacting Isilon Support for assistance with gathering and analyzing a packet capture of the session. You can create the service request here:

Thank you Sjones for suggestion. Actually where i was testing was virtual isilon, after a while i had a chance to use physical isilon. Though i still need to check the detail more, but it seems the connection and CA behavior goes as expected. Thanks for all your support!!
