The easiest way to connect to you iSCSI storage LUNs from Windows Server 2008 is by using the iSCSI initiator GUI. With the GUI you can easily make a connection with your iSCSI Storage by giving the ip-address and dynamically discover the LUNs (or Volumes) it has to offer. With the Windows Server 2008 R2 Core edition, you can start the GUI with iSCSICPL.exe.
In case you do not have the option to use the GUI (Core Server or when scripting the configuration), you can use the CommandLine Interface (CLI) Windows Server 2008 has to offer by default.
The iscsicli.exe command of Windows Server 2008 allows you to use the Microsoft iSCSI initiator without the GUI. Making it the perfect tool for scripting the iSCSI connections (Hyper-V Server shared storage). If you know the ip-address of your iSCSI storage and the IQN of the LUN you want to use (though it can be found with the command), you are all set to set up the connection and use your shared storage.
This post offers step-by-step instructions for the iscsicli.exe command.
