Problem with taking snapshot by iscsitarget

Hi all,
Now I’m trying to write a script to use the MS iscsitarget to take a disk snapshot automatically. Here is part of my script:

’ Get the Wbem Services object.

Dim WbemServices
Set WbemServices = GetObject(“WINMGMTS:{impersonationLevel=impersonate,authenticationLevel=pktPrivacy}!\.\root\wmi”)

’ Get the WtSnapshot class.

Dim WtSnapshotClass
Set WtSnapshotClass = WbemServices.Get( “WT_Snapshot” )

’ Take snapshot.

Dim WTSnapshot
Dim RetCode
Set WTSnapshot = WtSnapshotClass.Create( …)

My problem is I can not get the parameters of method “Create”.

Thanks & regards.

Where can I get information about this? Thanks!
