You shouldn't have any problems seeing the LUNs from using the fdisk command. The SAN's I've dealt with, I'd actually use fdisk to find the LUN's, parition and format, etc..

cat /proc/scsi/scsi [/COLOR][/B]file to see the luns in SAN

They are Dynamically added by following command

echo "scsi add-single-device A B C D">/proc/scsi/scsi
A is the host bus adapter (HBA) number
B is the channel id on the HBA
C is the SCSI ID of the new device
D is the LUN of the new device
