For the fresh install latest udev packages will be used, but for upgrade you can retain the previous version of udev packages.
The only thing customer need to do is to update the "/lib/udev/rules.d/80-drivers.rules" file with
SUBSYSTEM=="scsi", ENV{DEVTYPE}=="scsi_device", TEST!="[module/sg]", RUN+="/sbin/modprobe -b sg"
Customer can check this file on other RHEL 6 machines to get the feel of how this entry will be placed in this file.
