[PLUG] Ubuntu & Drive Order


So I've now got this 6 disc scsi drive array that I plan to set up as a 
Raid 5 array, but the problem I'm having is with Ubuntu. I added my Scsi 
card and plugged the drives in and everything boots great, but Ubuntu has 
now re-ordered my drives!

/dev/sda (sata drive) is now /dev/sdi, /dev/sdb is now /dev/sdg, and 
/dev/sdc is now /dev/sdh. The drives from the scsi array are now /dev/sda 
to /dev/sdf.

It all still boots and works fine, but my concern is if I ever add drives 
in the future (USB or SCSI) that it could reorder the drives in the scsi 
array. Would that cause any trouble for the raid software? is there a way 
to prevent it?

I'm holding off building the array until I figure this out, so replies are 
appreciated! :)

Thanks
Marc
