celerra or vnx-file xml api login example

Hi,

do you still have a problem there ?

I got the example code working posted in https://community.emc.com/message/921930#921930 written by john mcgeever.

Most of the code is well written and understandable, but I have some problems interpret the Class defenitions for the responsePacket object. I was not able to iterate trough the object items.

I was able to serialize it back to a text string usung the Xml serializer:

System.Xml.Serialization.XmlSerializer x = new System.Xml.Serialization.XmlSerializer(responsePacket.GetType()); 

x.Serialize(Console.Out, responsePacket);

I could not figure out how to map it to the defined  FileSystemQueryParams class.

Has anyone have a clue how to interpret the resonse object

below is the schema definition of the responsePacket - does that help ?

Rainer

                    Defines an optional string that is an exact copy of the attribute 'clientHandle' of

                Defines a response packet that is a top-level element of the XML contained in the body of the

                HTTP POST reply.

           

       

       

           

               

                   

                       

                           

                                Defines a response element that corresponds to the appropriate request element

                                in the request packet.

                           

                       

                   

                   

                       

                           

                                Defines the an extended response element that corresponds to the

                            Defines a fault that can not be attributed to any request, but is related more to

                            to the entire packet. For example, the message that was supposed to be a

                            request packet could not be parsed according to XML or defined schema rules.

                       

                   

               

           

           

               

                   

                        Specifies the API version of the response packet.

                   

               

           

           

               

                   

                        Specifies the time on the Control Station at the moment when

                        it generated the reply.

                        This attribute is present only when the request packet

                        contains no requests (empty packet). By measuring the roundtrip

                        time of an empty packet and using the value of this attribute,

                        the user application can determine the time on

                        the Control Station server with a relatively good precision.

                   

               

           

       

   

Hi Rainer,

I  have a query i need one API CifsShareQueryParams to be used to query , my question how should i use this below schema or should i import to VNX? how can i achieve this,

http://www.w3.org/2001/XMLSchema " name="CifsShareQueryParams">

   

        Defines parameters for the query that retrieves CIFS share objects.

   

   

       

           

                Specifies a mover or a VDM.

                        If this element occurs, filter out shares that reside

                        on this mover or VDM.

           

       

   

   

       

            Specifies a CIFS server NETBIOS name. If not specified, all shares

                    for the specified mover or VDM are retrieved.

       

   

   

       

            Specifies a share name. If not specified, all shares on the specified mover/CIFS server

                    are retrieved.

       

   

the Schema is merely a help (documentation) for programmers to understand the namespace and syntax of the API

There is NO NEED to install it on the VNX.

Not sure if you need more and I hate to beat a dead horse. I have a bunch of scripts to find shares, get qtrees and quota usage and raise quotas, create qtrees and shares, etc. Once you get past the first step this all is very useful an do-able.

Here is an old sample I posted a while back using PowerShell. I did try similar with C# while debugging in my early efforts but don't have that code and don't recall what I used to do the http posts/etc.

This might need some fleshing out but it works. One thing I do have to do is import the certificate (to computer account store) as we have a self-signed certificate.

It is basically how I do things today though I we now use LDAP. I have some code for that if needed.

Hi Chris,

always good to have examples posted.

Keep in mind though that the original post was about the VMX API and not Powershell.

Rainer

I guess I don't understand. I think he is asking about using the xml api which I am calling via PowerShell.

Frankly, I think he is trying to do exactly what I do though he might not be trying via PowerShell.(sounds like C#)

-c

Sorry – I didnt realize your PowerShell uses the XML API

I mixed it up with some other PowerShell commandlets that I have seen that use different ways
