APAR status

• Closed as program error.

Error description

• Serviceability improvements need to be made for fabric discovery
  and probe jobs.  It is almost impossible to understand the
  "trail" of where these requests for the discovery/probe jobs are
  coming from.  Need to see the "origin" of the job request and
  add that to the trace logging.
