OA57042: AFTER CANCELLING AN HCD I/O PATH REPORT AN ABENDC0D IOSVDFDP IOS530I DISCOVERY AND AUTOCONFIG UNSUCCESSFUL

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When using HCD I/O Path Report Selection HCD can and may
  use zDAC, ie. Discovery to complete report information.
  .
  If a User cancels the job by any means, ie. cancel TSO
  user or P the REPORT job, a subsequent abend may occur,ie.
  Log shows:

  .
   Subsequent Reports and/or zDAC discoveries will fail
  with abends and/or messges.
   In addition a Discovery Control Unit is left "orphaned"
  in HSA on the chpid that was used for discovery.
   If a future dynamic IO request involves changing and/or
  removing a chipd it may fail with:
  Unable to DEL chpid
  IOS1500I Activate failed. Reason=0170 can not delete chpid 36
  from CSS 1
  Desctext=system error - diagnostic info 4011 010B 02

  .
  This apar is created to fix the problem where a CU is q
  orphaned in HSA after cancelling the REPORT job.
  If the CU is already orphaned in HSA see z page for
  further instructions.

  ****************************************************************
  The HCD I/O Path Report and the HCD Discovery and
  Autoconfiguration processing performed by IOS may make
  temporary changes to the active I/O configuration by adding
  control units and devices that are used exclusively for
  discovery.  When one of these functions is terminated before
  completion (e.g.Cancel), the discovery control unit and
  devices may remain in the configuration and cause ABENDs,
  subsequent report failures, or autoconfiguration failures.
  
  In addition, if the hardware request to change the
  configuration during Discovery and Autoconfiguration
  controller discovery fails, devices or control units added
  temporarily for discovery purposes may remain.
  

Problem conclusion

• IOS discovery processing is updated to remove any control
  units or devices added for the purpose of I/O discovery when
  the function is terminated before completion of the function.
  
  IOS discovery processing is updated to remove any control units
  or devices added for the purpose of I/O discovery when the
  function fails while changing the hardware configuration during
  controller discovery.
