[SunHELP] disk/LUN

I'm dealing with a clariion disk array.  In part of
my setup, I have 3 RAID 1+0 's split equally into 2 
LUNS each, how can I determine what LUN on a 
specific raid group corresponds to the what disk that
the OS sees.  example: LUN1 on a RAID 1+0 appears to the
OS as c2t0d0, LUN2 on the same RAID 1+0 appears as
c3t0d1

I'm not so much concerned with the LUN order, I just 
need specific data to occupy specific raid groups.
