Contact your Netapp support or directly go to the "NOW" web site to 
download its linux host utility packages (e.g. 
netapp_linux_host_utils_3_1.tar.gz) . Its installation should be 
reasonably trivial. After install, there will be a command called 
"sanlun" that can tell you the mapping between /dev/sd* and filers luns:

For example:
[root at acamar wendy]# sanlun lun show
   filer:      lun-pathname   device filename  adapter  
protocol          lun size         lun state
wcheng-1  /vol/cluster1/lun0  /dev/sda         host5    iSCSI           
300GB        GOOD  
wcheng-2  /vol/cluster2/lun0  /dev/sdb         host6    iSCSI           
300GB        GOOD
