IT33032: PROBE FAILS TO EMC DELL UNITY DEVICE DUE TO LARGE NUMBER OF LUNS/MAPPINGS EXCEEDING THE CONFIGURATION CONSTRAINTS.

IBM Spectrum Control 5.4.0 (August 2020)

APAR status

• Closed as program error.

Error description

• The REST API for EMC Unity caps at 2000 entries for a single
  page of data, no additional data is collecting due to the cap
  at 2000 entries. If the storage device has more than 2000 LUN
  Mappings no additional data will be collected resulting in the
  Probe failure.
  
  Probe fails with the following
  error:
  HWNEP0135E External process failed with error code 99.
  
  The corresponding ?Probe_ExternalProcess.log?
  displays:
