|I've been here before, and I found no documentation on how to address it, but I figured it out on my own. Here's what I did. This used to be a little simpler on WIndows 2003, but they don't let you install plug-and-play hardware on Windows 2008 manually, you have to insert the device (Except by following the instructions below)|
On the old server, I installed Microsoft's iSCSI initiator driver. Once installed, I "updated" the driver to be that of the new storage controller, in your case, the controller of the IBM server. I rebooted and then shutdown and took an offline image of the server. I restored it to my new server and corrected the other driver and licensing issues. Do this at your own risk, because it's a huge waste of time if you don't do it right. Good luck.
