I did it like this on my REHL5.2 with SAN storage connected:
My objective is to give a partition a static name.
1. get the info from the partition, for example sdb3
# udevinfo -a -p /sys/block/sdb/sdb3
2. pick up the size info(all partitions have different size, I use the 
size to identify the partition), and create /etc/udev/rules.d/20-user.rules:
BUS=="scsi",SYSFS{size}=="398636417",SYSFS{start}=="62",SYMLINK="newname"
3. # /sbin/udevstart
4. use the static name /dev/newname to mount to a folder
5. (option) put a line into /etc/fstab to make it work on reboot


hope it help.
