How to create a lun using generic wbem query.

[Ritesh Nailwal]

Hello All,

 

I am creating a single SMI-S (java client using java wbem service ) for EMC SMI-S provider (version) and netapp SMI-S agent.

 

I am stuck with creation of LUN, ( I could not find the exact syntax for creating a lun using wbem )

 

calling AddInstance method on StorageVolume is saying that operation is not suppported.

 

I will be highly grateful if you guys can help me for creating LUN using generic SMI-S method.

1. The object CIM_StorageConfigurationService has a method

CIM_StorageConfigurationService.CreateOrModifyStoragePool()

That will create a RAID set.

2. The object CIM_StorageConfigurationService has a method


CIM_StorageConfigurationService.CreateOrModifyElementFromStoragePool()

That will create a LUN from the pool (RAID set).

3.The object CIM_StorageConfigurationService has a method

CIM_StorageConfigurationService.ExposePaths()

That is used to allow a Host to access the LUN over fibre Channel

These are the basic steps. but it is much more complicated. You
need to read the SMI-S / Block book / Block Services Chapter
to get all the details.

Hi All,

I am developing  the Generic SMI-S client for EMC and NetApp.

 

For EMC I have done all the operations (LUN Ctration, Meta Lun creation, Storage pool Creation.... etc)  but in case of NetApp I am able to do the only LUN cration and aggregate creation.

 

I want to be helped in the NetApp specific operations (retrieval and creation) i.e. Share, IGroup, DataSet etc....

 

can U guys help me about this. (Some NetApp CIM api documentation will certainly help but I could not find such document.)

 

I will be highly gratefule to you.

Ritesh Chandra Nailwal

Hi,

 

Yes, you can access ECOM and its SMI-S Providers and any other vendor providers.  You should start by reading

 

An Introduction to Storage Management in Windows Server 2012

http://blogs.msdn.com/b/san/archive/2012/06/26/an-introduction-to-storage-management-in-windows-server-2012.aspx

 

One of the diagrams in this posting illustrates what Steve describes below.

 

The Storage Management API (SMAPI) has two interfaces; one a WMI set of classes and the other a PowerShell Cmdlet set.  The WMI form is documented here

 

Windows Storage Management API

http://msdn.microsoft.com/en-us/library/windows/desktop/hh830613(v=vs.85).aspx

 

The PowerShell Cmdlets you can reference from

 

Storage Cmdlets in Windows PowerShell

http://technet.microsoft.com/en-us/library/hh848705.aspx

 

To fully use these interfaces the underlying SMI-S provider must support the Windows 2012 storage management requirements.  If not or if there is some capability that you need which is not supported, you can bi-pass these two interfaces and go directly to the target provider by using the Pass-thru API for Extensibility.  This is essentially a basic WBEM Client that implemented as a WMI provider.  You can therefore access it through WMI or PowerShell.  I did some searches but could not find any official documentation posted for it only references to the interface.

 

I hope this helps.

 

Peter

Hi Steve, I want to develop some application to query EMC SMI-S Provider on Windows. Do you know if it is possible to access the CIM class using visual studio .NET? Looks like we can access using root/EMC namespace but I can't find how... I found some information that tell "localhost:5988" to reach namespace (the port 5988 is the ECOM service) but I wasn't able to reach it even the service is running and the ECOM server web page is available..

 

Which Tools did I have to run to reach it and interact?

 

Thanks

Hi All,

I am trying to create LUN using EMC SMI-S provider. I had some confusions with EMC Developer's guide so I just started searching for difference between LUN and Volume for  EMC Provider ( and there after NETAPP/ Hitachi). It is becoming confusing to find difference between them. It will be a great help if I can get some document/link that can be followed to develop API for SMI-S client side requests for EMC+Netapp

I am looking to create, delete and modify LUN and Volume for both the vendor starting with EMC. For now I am using "EMC® SMI-S ProviderEMC®  SMI-S Provider  Programmer's guide".

Any help is appreciated

Thanks

Ankur
