Hi All,
I am working on a application in which I have to create DFS shares in HNAS system.
As I am quite new to HNAS so don't know how to proceed on this.
It would be great if anybody can guide me on this.
My application details
ASP.NET v2.0 with C# or VB.net
Thanks in advance.
Regards
Sandeep
Hi Sandeep,
Can you please confirm - do you need to create CIFS (SMB) shares from scratch, integrate existing HNAS CIFS shares into DFS, or both?
Thanks,

Hi Michael,
Thanks for the quick interaction.
Here is my complete requirement.
I have to create DFS shared folder in HNAS systems with the help of the my application ( Web based with asp.net C#)
from the scratch.
I have a application which creates DFS shared on Windows systems.
I hope i am clear to you.... if not plz let me know.
Thanks
Sandeep
Sandeep,
Let me rephrase my question. HNAS allows you to create CIFS shares, which behave like "regular" Windows shares. Then you can integrate a number of CIFS shares into DFS - Microsoft Distributed File System - which is external to HNAS. So the questions are:
You can always create a script using HNAS' CLI, but once again, it all depends on how well this will play along with your application.
Thanks,

Let me explain my current behavior of the application.
Suppose I want to create DFS share name "TestABC" on a windows system [system name = XYXX, path : E:\\ABCD]
e.g. DFS path : \\Domain.com\SQA\TEST\TestABC
where
\\Domain.com\SQA : Domain based namespace
TEST : Folder
TestABC : Folder target
Now DFS share will be created successfully using my application. And TestABC target is mapped to XTXX:\E:\ABCD folder.
Now same has to implemented in HNAS system, so that user can create DFS share in HNAS system.
I don't know how implement this.
What i understood from your reply is that first I have to create a CIFS share on HNAS.
Then CIFS share integrate with DFS shares.
Now I just wanted to know is there any API or set of DLLs available to connect HNAS system and create share on that.
or any script is available then pls share ...
Thank
Sandeep
HI Micheal,
Today i got some SSC command and PLink Utility - Putty command. What are these commands and how I can use them in development. Also request you to pls explain
following terms from development prospective.
Admin Node
SMU
EVS
CISF
I would really appreciate if you can respond on this at the earliest.
Thanks
Sandeep
Hi Sandeep,
Trying my best to respond quicker.. still have the time difference though . Here goes:
Most HNAS management functions can be performed through Web Manager, a browser-based GUI hosted by the SMU, but some may require CLI. There are two types of CLI: SMU CLI and server/node CLI.
The SMU CLI can be accessed using any SSH client from the public network. The node CLI can be accessed in the following ways:
Plink utility you mentioned above is an SSH client from the Putty family of utilities. I wouldn't recommend using it at this point, rather try using the SSC utility that you also have. It will allow you to log into the node interactively or execute commands remotely - which is what you can use to script the process of share creation.
There is a lot more to it, of course. I suggest you register on the HDS Portal site (if not already) where you can download the product manuals.
All the manuals are also available through the SMU GUI (Web Manager):
As far as DFS, it's a whole different story. First I recommend to get familiar with the HNAS itself, and we can talk about DFS later.
Hopefully this helps.
Cheers!

Hi Michael,
Thanks for the quick response. I was not in office for last couple of weeks, so could not respond to you earlier.
I really apologies for that.
With my current application I am able to create Folder in HNAS system successfully. But I am not able shared that folder programmatically. I was getting som NTFS permission error.
Even I tried to access that Folder in Windows Explorer, I can view the folder but not able to shared that folder manually as well.
Please help. I am hoping your response at the earliest.
Thanks
Sandeep
Hi Sandeep,
As I understand this, and correct me if I'm wrong, you can actually create and *share* a folder from HNAS, but you can't *access* it from the Windows client due to a permission issue. Does this sound right? If yes, you will need to configure access permissions for your client(s), which may vary a lot depending on your environment, user/group accounts, AD configuration, etc.

Hi Michael,
I have to create a Shared Folder on HNAS.
With my current development so far I am able to create Folder on HNAS system but I couldn't make that folder Shared with other peoples. I mean I am not able to add permission on that folder.
Also I heard that there are some APIs available to create shared folder in HNAS,
Please let me know how I could I use those API in my development.
I highly appreciated if you can reply me asap.
Thanks in advance.
Hi Michael,
Thanks for the answer.
I am using "BUILTIN\Administrators" in Windows. So could you please let me know what is equivalent of "BUILTIN\Administrators" in HNAS.
Thanks
Sandeep
What type of permissions you have set on the HNAS for the CIFS share, Following are the sharing permissions available
>>Full Control
>>Change
>>Read
If you want to modify the contents of the share then Allow permission for Full Control/Change.
Also select the appropriate Security mode - If you have both type of clients (CIFS/NFS) access the Filesystem or share , then set the Security mode to Mixed or else either go with Unix Mode/NT mode.
Sandeep,

The closest would be Administrators local group in HNAS, but then again, it is important what you use this for. The local groups in HNAS have to do with the filesystem (data) access. Management users (HNAS administration: creating filesystems, shares, etc.) are different.
Hi Sandeep Sharma,
Have you been able to successfully integrate your application with HNAS?
Regards,
-Michael
Hi Michael,
Yes I am able to integrate HNAS in my application. "Administrators" work for HNAS.
I really apologies for delay in replying.
Actually now we have to integrate NetApp also, so I was busy in R&D for NetApp.
Once again thanks for your kind help and support.
Thanks
Sandeep
That's great - I'm glad it worked for you! Thanks for taking the time to respond.
Cheers!

Hi Michaeal,
Is there any way which we can determine that the Server on which I am creating a folder is HNAS Server or Windows Server.
Thanks
Sandeep
Hi Sandeep,
There are many ways to distinguish HNAS from the generic Windows server, but it really depends on how you access HNAS. Are you using 'ssc' utility as we discussed previously?
If SNMP is enabled, you can query the server type that way. If you can access some of the SMB protocol data the negotiation steps include a software or OS information about the server you are talking to. If you are connecting over SSC then I expect that will only work to an HNAS?
Yes, SSC will work only to an HNAS.. but the question is related to HNAS specifically. It is also much simpler than to setup SNMP, and it should be used anyway in this particular case for scripting.
CIFS stands for Common Internet File System and is just another name for the Microsoft protocol for file sharing (also called SMB). CIFS shares behave exactly like a regular Windows server share.
Really we shouldn't be using the term CIFS any more as Microsoft deprecated it and allowed the use of the term SMB (Server Message Block). There are now several version of SMB, each of which supported or introduced by different versions of Windows. The latest versions of windows support up to SMBv3, with notable older versions being SMBv2.1, SMBv2 and SMBv1.
SMBv1 (also called SMB a lot of the time) use to be called CIFS, or bits of it did, then someone changed there mind and renamed it but some of it was still CIFS and... in short it is all a bit messy. It would be nice if we could draw a line under it and start calling all versions it by their more modern title of SMB. People tend to use the word CIFS as a shorthand for Windows Network File Sharing in general. The other common Network File Sharing protocol is NFS, used by many Unix/Linux/MacOS/Posix/BSD systems.
Thomas, I agree with you in general that proper naming should be used, but for the purpose of this discussion I'd rather stick to terminology that is current for the product and well understood by customers. Basically, I'm trying to say that as long as "CIFS" is prevalent in the HNAS documentation, GUI, and CLI, I would keep it simple and not go into a terminology debate (at least for support questions).
We have this horrible feedback loop though where we don't update our terminology because it is what customers use and customers use it because it is there in our documentation
I agree. It is also a much wider problem of terminology acceptance and market diffusion.
