I'm trying to configure the Microsoft iSCSI Initiator programatically from within C#. I've found very little documentation about how to do this using WMI. Basically I want to:

Create a target portal
Once a target has been discovered, log in to the target persistently

If this can't be done with WMI, are there any examples, good documentation, or can someone point me to the correct methods to do this using the iSCSI DDK (using C).

Thanks!

There is an SDK available under NDA that has documentation of all the WMI
classes and Win32 APIs.

Basically, you already have the MOFs (which get copied to C:\Program
Files\Microsoft\Microsoft iSCSI Initiator when you install the initiator.
To do what you want, create a new instance of
MSiSCSIInitiator_SendTargetPortalClass to create a new target portal and
then call the Login method on the MSiSCSIInitiator_TargetClass class and
specify IsPersistent parameter as TRUE.

This will work with C#, VBScript, etc.

Jeff, thanks for your message. I tried to implement what you said but I'm running into a lot of problems ... mostly because the documentation is so light... I'm getting an error "Invalid method Parameters(s)" on the last line of the code below. I think the biggest problem is not knowing what properties we need to fill in or not. Can you look at the code and give me any recommendations? Am I on the right track

BTW, my company does have a NDA with Microsoft, who would I contact about getting full documentation for WMI and win32 api calls

Thanks

Charli
