IT48799: STORAGE INSIGHTS FAILS TO COLLECT DATA FOR HITACHI VSP G-SERIES STORAGE SYSTEMS WHEN THE VOLUMES DO NOT HAVE A LABEL.

APAR status

• Closed as program error.

Error description

• When Storage Insights attempts to collect performance data from
  Hitachi VSP G-Series systems, the probe initially completes
  successfully on the Data Collector and generates the expected
  output package.
  However, during server-side processing, the Probe Data Processor
  encounters incomplete or missing attributes within the device
  metadata. Specifically, multiple volumes in the probe payload do
  not include a valid value for key fields required by the parser.
  
  Because these fields are necessary for building the internal
  data model used by PDP, the post-processing step fails and no
  processed performance data is produced for the affected Hitachi
  system.
  As a result, the performance collection task fails during
  processing and Storage Insights is unable to generate or display
  updated performance metrics for the device, leaving the system
  without performance visibility even though the probe execution
  appears to complete normally.
