NICE!! The only problem  is that the box seems lacking those python scripts:

        ls /usr/lpp/mmfs/samples/util/
        makefile  README  tsbackup  tsbackup.C  tsbackup.h tsfindinode 
        tsfindinode.c  tsgetusage  tsgetusage.c  tsinode tsinode.c 
        tslistall  tsreaddir  tsreaddir.c  tstimes tstimes.c

Do you mind sending me those py files? They should be 3 as i see e gpfs 
options:  gpfs, gpfs-ops, gpfsops  (dunno what are the differences )

Regards,
Salvatore
