     Hi,
 
     We are currently experiencing some system performance problems.  As
     near as we can tell, part of the problem may be that we have 3 of 6
     RAID drives in our proudction volume set running at 100% utilization
     for most of the day (according to GlanceXL).  The other 3 RAID's are
     running around 35%.  I would like to try to find out two things:
 
        1)  List of files on each ldev.  (I know I can parse this out of
     LISTF,3 but I don't have time to write a program for this.  I also
     don't own MPEX).
 
        2)  Some statistics on number of I/O's per file on each LDEV over a
     period of time.  We have SCOPE/XL with Laser/RX and Perf/RX, but can't
     seem to wrestle this information out of these.
 
     Bottom line:  I want to find out which files to move off the heavy use
     LDEV's to spread the load.  Also, a utilty to move the files (PRIV)
     would be handy!
 
     Does anyone have any suggestions?  Is there anything in MPE that can
     help?  The CSL?  A feature we are missing in Glance or Perf or Laser?
 
     System Specs:
        HP3000 996/800 w/ 2 Gigs Memory
        MPE 5.0 Express 2
 
     TIA!!
