3Par MPIO Driver for Windows 2003

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.

Hi

I think you should disconect all drives from your server.

then un-install EVA MPIO after reboot install 3PAR MPIO reboot

and then install EVA MPIO.  reboot.

now you can reconnect all drives.

You have no Need to Install the 3PAR MPIO Driver. Simply use the default MS MPIO and ad 3PARdataVV in the Device ID Field.
That was not planned in this way.

That's what I thinking but couldn't find a place to enter it.  I ended up just P2V'ing the box.

MPIO Admin > MPIO Devices > Add > Add MPIO Support > Device ID > 3PARdataVV or mpclaim -r -I -d "3PARdataVV", but this makes a immediate reboot
