APAR status

• Closed as program error.

Error description

• Probes and performance monitor jobs fail referencing incorrect
  username/password despite confirming both are correctly entered
  in the Spectrum Control GUI.  Failure messages such as the
  following are found in probe job logs:
  2016-03-09 05:44:51.922-0700 HWN021538E The username <username>
  or password is wrong on CIMOM https://storage.example.com:5989
  This is caused by invalid credentials that should have been
  removed from the Spectrum Control database tables when a
  previous data source (CIMOM) was removed and/or updated.  Probes
  can still refer to the invalid info and the jobs will fail as
  noted.
  RECREATE STEPS:
  Remove a switch or subsystem and re-add it with new data source
  credentials, observe probe failures as noted

Local fix

• Contact support for validation of the problem via database table
  queries.  Once confirmed, removing all monitored devices that
  are associated with that CIMOM data source and adding them back
  in clears the errant database table entry, and configures probes
  and performance monitor jobs to refer to the correct
  credentials.

Problem conclusion

• This APAR fixes the issue of the probe ending in failure in this
  case of multiple data sources (1 successful and 1 failure).
  Further refinement for multiple data sources is targeted for a
  future release.
  
  The fix for this APAR is targeted for the following maintenance
  package:
  
  | refresh pack | 5.2-TIV-TPC-RP0010 - target 2Q16
  Fixed in IBM Spectrum Control 5.2.10.
