  QUESTION
 
       After I updated to 3.2.4, the dd command gives an "out of
       space" error.  I didn't get this error before.  What hap-
       pened?
 
  ANSWER
 
       The method the dd command uses to read a variable length
|      file was changed.  (A variable length is used when the phys-
|      ical block size in smit is set to 0.)  This has been cor-
       rected with APAR IX38287 which is in the U493250 PMP tape.
       If you do not want to update to 3.2.5, order PTF U422652.

  WORKAROUNDS
 
       o   Since dd now must fill its buffer EXACTLY, the use of a
|          bs=#### on the command line will fail unless the size
|          specified is at least as large as the block size on
|          tape.
 
           Use "tcopy /dev/rmtX" to read the tape and find out what
|          the actual block size on the media is.  Take the largest
|          block size reported by tcopy and use this block size as
|          the value for the 'bs=' or 'ibs=' parameter to dd.
