Would anyone by any chance know how to rename things using udev that are logical links to say an external raid?

Main idea is that I have an esata nvidia controller with raid. I plug in two external sata drives and through the controller put them into a raid 0. When linux boots (2.6 kernel), it detects all the drives as scsi devices and creates dev's for them. It also creates a logical link inside /dev/mapper so that you have an access point to the raid, which subsquently locks mounting of the individual dev links - which means that everything is working as it should. I can use the drives as I like via the /dev/mapper/ link, however the name that is generated under mapper is some funky nvidia_(blah!!!) name which I suspect is either the kernel id or sys id, but I can't find a reference to either. The blah part is not affected by the disk label ... I believe it has something to do with raid device name which is generated everytime the raid is broken and recreated. So, what I would like is a way to nail down the name that gets plunked in /dev by a kernel id or more likely a sysfs or pci id by using udev. However I don't know where to look to find any of that information as it relates back to the devices attached to the raid controller. (If it exists....)

Any replies are much appreciated, thanks in advance guys and gals.
