Error description

• OA35600 (sysroute of OA34306) was created to correct the
  following symptoms:
  
  IEC331I 050-012(041A041D,M9SN01),P27890R,RESTORE,VALO,IGG0CLE5
  
  or
  
  ADR709E (001)-VDSS (01), AN ERROR OCCURRED IN THE STORAGE

  WITH NEWNAME P27890.SAMS0.T. SMS MESSAGES FOLLOW.

  RETURN CODE IS 50 REASON CODE IS 12 IGG0CLE5

  RETURN CODE 50 REASON CODE 12
  THE MODULE THAT DETECTED THE ERROR IS IGDVTSCU
  SMS MODULE TRACE BACK - VTSCU VTSCT VTSCM VTSCR SSIRT
  SYMPTOM RECORD CREATED, PROBLEM ID IS IGD00012
  
  This occurs when the data set being processed is larger than the
  volume its targeted to be created on and no VVDS exists on the
  volume.
  
  
  
  The window occurs when the dataset
  is large enough to fit on the volume but does not leave enough
  space for the VVDS.  To compound the issue, IGG0325B will set
  the DS4VVDSA bit indicating there is a VVDS even though the
  allocation request for the VVDS failed with IEC331I 050-012.
  This setting of this bit when there is no VVDS will cause all
  future best-fit requests to fail with the same messages.  This
  apar was created to close the window and ensure the DS4VVDSA bit
  is only set after a successful VVDS allocation.
  
  This APAR will need to be applied with OA39074.
  

Local fix

• Ensure a VVDS is allocated to all volumes that had experienced
  the IEC331I error message.

Problem conclusion

• In such a case as described above, when the FMT-4 indicator
  for VVDS dataset did not reset correctly, DADSM could no
  longer reserve the space for the default 10-track VVDS
  dataset on that volume when there is such unique allocation.
  The allocation would fail unless SMS can find a bigger empty
  volume or an empty volume with space less than the non-VSAM
  dataset to avoid such window described.
  The FMT-4 VVDS indicator will be corrected as long as there
  is a successful allocation on the volume.
  This APAR will resolve the unique allocation problem described
  above by correctly resetting VVDS indicator in the FMT-4 DSCB
  when the allocation for VVDS fails.
  During the test of DADSM fix for the recreate scenario, SMS
  has set a non-zero return code for a successful allocation of
  the dataset. As a result, DADSM fix,OA38691 will require SMS
  fix in OA39074 to resolve the allocation completely.
