Then I sujects you to use a LiveCD distro to test if
the system can see the luns somehow
or maybe the rescue CD can allow you see if the HBA
can see all the LUNs (in the debug console alt+F3 or
alt+F4 maybe)

because maybe there is something outside the linux
kernel (hardware or SAN configuration) which disable
you to see all the LUNs
