Here's my situation. I have a Windows 2003 Server that's currently connected to an EVA array and is using the "HP MPIO DSM Manager." I've presented a new 3Par disk to the server but it appears as eight separate devices (one/path) rather than one. I attempted to install the 3Par MPIO driver (1.0.23_780-200072) driver but it fails pretty quickly. I'm hestitant to uinstall remove the existing DSM manager, fearing what will happen to the EVA disk. I've restarted and reviewed the pre-reqs but don't see anything obvious. I've attached a screenshot of the error.
