Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• IEC608I received during the creation or extend of a data set.
  Diag codes 0820040B (create and extend to a new volume) and
  0853040B, 0854040B, 0855040B (extend).
  ----------------------------------------------------------------
  The diag codes (0820040B, 0853040B, 0854040B and 0855040B) mean:
  - DSCB is not format-0 DSCB and VERIFY=YES.
  
  This essentially means that the VTOC Index believes a given DSCB
  to be available for use, but when the check was made to ensure
  the DSCB was available (FMT0 DSCB), it was not a FMT0 DSCB
  (generally referred to as an orphan).
  
  It has been determined that the potential for the orphan
  scenario has been around for years, but is now being
  discovered repeatedly and frequently than before because of a
  missing function in DFSMS 2.3 which was recovered by OA55296.
  The missing function resulted in an exposure of orphan FMT-3s
  not being cleaned up and corrupted VTOC as a result.
  The act of disabling a VTOC Index does not generally impact
  anything other than performance of VTOC access.
  Therefore it is wise to run an ICKDSF job to convert the VTOC
  to an IX format VTOC as soon as possible.
  
  Currently, we are unable to determine the reason the DSCB was
  marked available in the VTOC Index and not 'converted' to a FMT0
  DSCB in the VTOC.
  
  Therefore the scope of this APAR's mission has shifted to
  providing the RAS necessary to help clients identify and correct
  consistent issues with VTOCs and their Indexes.
  
  If your site experiences this scenario, please perform the
  following;
  
  a) DFDSS Print of the VTOC and VTOC Index with the following
  SYSIN
  //SYSIN    DD *
      PRINT INDYNAM(volser)
      PRINT INDYNAM(volser) DS(SYS1.VTOCIX.llq)
  b) Confirm the PTF for OA55296 is applied and 'active'
  c) Run an ICKDSF job with the following SYSIN
   - REFORMAT DDNAME(VOLDD) VERIFY(volser) REFVTOC
  d) If the VTOC is not in IX format following step 'c', run
  ICKDSF
   - BUILDIX  DDNAME(VOLDD) IX
  e) DFDSS Print of the VTOC and VTOC Index with same SYSIN
  f) 'Log' this volume as having gone through this process with a
  date
  
  If the results of this procedure do not result in a IX format
  VTOC, please terse and ftp the DFDSS output from steps 'a' and
  'e' above along with the ICKDSF joblogs.
  

Local fix

• Use ICKDSF to rebuild the VTOC Index.  However, ensure the PTF
  for OA55296 is applied prior to doing so.

  If users code this keyword, RETRY(STAT011) in the DEVSUPxx
  parmlib member, DADSM allocation will detect the failed
  allocation on the disabled-index VTOC due to the described
  diagnostic codes(STAT011), convert the disabled-index VTOC to
  non-index VTOC(OSVTOC), and restart the allocation one more
  time.
