I don't think this is what the original poster was asking - if you
look at his example, you will see that he is asking how to obtain 
SL5.4 via rsync, not how to set up rsync on SL5.4.

One can explore the exported modules on an rsync server by using the 
double-colon syntax - to list all availableshares on the SL rsync server

$ rsync rsync.scientificlinux.org::

scientific     	Scientific Linux area
fermi          	Fermi Linux area
redhat         	RedHat Linux area
extra          	Extra Repositories
fedora         	Limited Fedora Area
devel          	SL devel area


Going down the 'scientificlinux' path 

$rsync rsync.scientificlinux.org::scientific
[...]
drwxr-xr-x        2048 2009/11/03 13:57:14 54

To rsync a copy of SL5.4 for 64-bit architecture, the path
is rsync.scientificlinux.org::scientfic/54/x86_64 - try that
in your command below 

$ rsync -vaH --delete --exclude=".~tmp~" rsync.scientificlinux.org::scientfic/54/x86_64 /storage/xxx/yyy

Hope this helps,
