OA49473: PREDICTIVE FAILURE ANALYSIS PFA_COMMON_STORAGE_USAGE COLLECTION FAIL RC28 AIRHMCSA AIRHMCSC PFA

APAR status

• Closed as unreproducible in next release.

Error description

• Predictive Failure Analysis (PFA) collection fails with RC28.
  systemName.COLLECT.LOG in the PFA zfs for
  PFA_COMMON_STORAGE_USAGE will contain the following messages:
  
  Started data collection at 11/24/2015 17:17:11
  AIRHMCSA: Process the CSA GQEs are failed. Data table is full.
  AIRHMCSC: AIRH1CSA return code ->00000028
  
  This is occurring because a table PFA collects data in from VSM
  owncomm data has reached its capacity.  If owncomm data, GQEs,
  represent more then 1279879 entries, the collection for
  PFA_COMMON_STORAGE_USAGE will fail.

  failed.
  

Problem conclusion

Temporary fix

Comments

• Code will be changed in a future release to handle the
  scenario where the table can fill so that collections
  will be successful with large numbers of storage obtains.
  The number of storage obtains required to be active for
  the original problem to occur was over 1.27 million.
  The APAR fix was provided in hbb77a0.
