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 :-)
