R710/PERC H700/H800/MD1200 disk naming

Have a R710 running RHEL4.8 with a internal H700 supporting two virtual
drives using internal disks and a H800 supporting two virtual drives
in an external MD1200 enclosure.

It seems that the device name (/dev/sd?) that is assigned to each virtual
drive is somewhat arbitrary.  It was in order of creation, but after
a reboot, it changed to order of enclosure/drive.

This, as you can imangine, is not a good thing.  What is the best way
of locking a device name to a virtual disk?  udev?
