New pci device after 2.3 install

Hi Team,

I was running proxmox 2.2 in a cluster of 3.

I backed up all the images and then reinstalled from scratch 2.3 and restored the images.

Now in the images, windows 2003 machine, windows detects a new hardware, a pci device but cant find any drives.

The hardware host is an IBM 3650 x series unit.

Could anyone guide me on what this new pci device could be.

Here is the a bit of the string from the prooerties tab of that unknown pci device "PCI\VEN_1AF4&DEV_1002&SUBSYS_00051AF4&REV"

Cheers,

Raj
