Issue

  • For storage systems attached to a HiCommand Device Manager datasource, some are reporting performance stats and some do not
  • No errors are shown in the datasource in OCI
  • The API to report the performance stats returns an empty set, which can be confirmed with the following steps:
    1. Download and extract an error report from the datasource
    2. Open one of the numbered folders with the storage performance report: ErrorReportName\acq\storageperformance_<datasourcename>_656_2021_02_24_11_01_32_742\1614163099532
    3. Open the recording_storageperformance-<datasourcename>.dat and search for the storage with the missing stats
    4. The request will have the storage name, and the response will return a list of stat names and variable types, but no actual stat numbers
