 ... and the envelope please...

  The PTF for disk balancing for V4R2 is
     ...(drum roll)...

        SF48479

 For V4R1, the PTF is SF48378

Note:  There are MF PTF's that are pre-req's for these SF PTF's.  The SF
basically has the DSKBAL command in them, the MF's have the actual LIC code
that runs at IPL that does the disk balancing.
If you order the SF's, you get the MF's as well if you do not currently
have them.
