Netapp filers running 7mode, this has been a moot issue for user running OSX 10.6.8 or 10.8.5. because they were using a true SMB client.
OSX 10.7 this all changed, Apple tried to use SAMBA, a SMBlike util, but only supported SMBv1
OSX 10.9 (Mavericks), Apple has abandoned the SAMBA, and written their own SMB server & client, and rumored to be MS-SMBv2 compatible.
And I can attach to my SMB share on our 7mode filer, and everything is working fine.
Now the curveball for all Mac OSX version, does it work under Netapp Cluster Mode env.?
So far, its not working. They are saying Mac's are not supported.
I asked: You mean yet or not at all?
Still pending an answer.
