APAR status

• Closed as program error.

Error description

• ABEND0C4 pic04, pic10, pic11 in IGWBLMRD (UA48501) +1148, or
  other PDSE CSECTs/modules.  This may be followed by ABEND0F4
  rc24 in IGWDSAAC or IGWISRCH, or other PDSE CSECTs/modules.
  .
  Problem is due to Media Manager overlaying various storage areas
  in PDSE address space.
  .
  ADDITIONAL SYMPTOMS:
  Media Manager ICYTRACE logrecs for module ICYBLD64. The MMPB
  control block in these logrecs will show MMPB+64 = 001C1C0C.
  

Local fix

• Restart PDSE address spaces.
  
  Circumvention: do not install OA30025 or remove OA30025 or
    disable zHPF by by use of the SETIOS command or updating the
  IECIOSxx member of parmlib to specify ZHPF=NO.

  *                      A CORRUPTED BACKUP DATA SET.  IN MOST   *

  *                      PDSE DATA SET BACKUP PROCESSING.  THIS
  *                      BUG CAN OCCUR UNDER THE FOLLOWING
  *                      CONDITIONS:
  *                      1. THE FIX FOR OA30025 IS INSTALLED
  *                      2. THE PDSE TO BE BACKED UP RESIDES ON
  *                         A DEVICE WHICH SUPPORTS HPF CHANNEL
  *                         PROGRAMS.
  *                      3. HPF PROCESSING IS ENABLED
  *                      4. THE IO IS REQUESTING BLOCKS OF DATA
  *                         THAT FRAGMENTED ACROSS MULTIPLE DASD
  *                         EXTENTS (MORE THAN APPROXIMATELY 18)
  *                      5. THE BLOCKS WHICH ARE TO BE READ FROM
  *                         ANY SINGLE EXTENT ARE CONTIGUOUS
  *                      PDSE BACKUPS TAKEN AFTER THE INSTALATION
  *                      OF PTFS FOR OA30025 OR OA34009 SHOULD
  *                      BE CONSIDERED SUSPECT.  BACKUPS TAKEN
  *                      JUST PRIOR TO ABENDS IN THE PDSE ADDRESS
  *                      SPACE ARE THE MOST SUSPICIOUS.  A SYSTEM
  *                      CAN BE PROTECTED FROM FURTHER EXPOSURE
  *                      BY ONE OF THE FOLLOWING MEANS:
  *                      1. INSTALLING THE CORRECTIVE MAINTAINENCE
  *                      2. BACKING OFF OA30025 AND OA34009 UNTIL
  *                         THE CORRECTIVE MAINTAINENCE CAN BE
  *                         INSTALLED.  NOTE: OA30025 IS SHIPPED
  *                         IN THE BASE FOR Z/OS V1 R12 (HDZ1C10)
  *                      3. DISABLING ZHPF PROCESSING
  *                      THE PTFS FOR OA30025 AND OA34009 HAVE
  *                      BEEN MARKED AS PE TO PREVENT ADDITIONAL
  *                      CUSTOMERS FROM EXPOSING THEIR SYSTEMS
  *                      TO THIS ERROR.  THESE FIXES WILL BE
  *                      RESHIPPED WITH A PRE FOR THIS APAR.
