You can use udev with scsi_id to map that lun always on the same place
instead using lvm to find volumes.
There is another thing you should consider. It is cLVM not LVM.

you to name your
volumes and helps to track them down when the system
is restarted.
There are similar problems when SCSI ID numbers get
swapped around.
yes, I know what you mean
I was looking for something like ext{2,3} label for
the filesystem but I could'n find anything for gfs :-(
so I am hopping that PowerPath kernel module always
identify the LUN with the same emcpower device :-)
if that is not true I will be forced to move to LVM
under GFS :-)
thanks
