look the LUN ID is supposed to be the number here:
for example:
c3t18d51s2
LUN ID = 51, because it is d51 (disk #51).
but be careful, it's tricky.
I suggest you trace your disks.
It seems that you have two controller (c3, c4)
and on C3, you have three targets:
t4, t14, t18
(PS: for detailed description, check your SAN to figure out why they appear as 3 targets, but that's not really important)
now your LUNs appear to be out of order:
d39, d40
d104,
d150, d151, d154
so try to MAP each LUN on your SAN to each d#..
I hope that helps !
