IT20740: TIER CAPACITY % FIELD IS BLANK IN SPECTRUM CONTROL DS8K CAPACITYVIEWS

IBM Spectrum Control V5.2.15 (August 2017)
IBM Spectrum Control V5.2.15.2 (November 2017)
IBM Spectrum Control V5.2.16 (March 2018)
IBM Spectrum Control V5.2.17 (May 2018)

APAR status

• Closed as program error.

Error description

• In the volumes panel of the Web UI the entire Tier Capacity %
  column is blank.  This is because DS8K r8.2 firmware added a new
  disk class (DISK_CLASS_SOLID_STATE_TP, which maps to disk type
  of FLASH in DS8K User Interface) - this resulted in some
  unexpected behavior when Spectrum Control probe tasks attempted
  to handle this new disk type.
  
  Essentially the probe post-processing of the data resulted in
  null/unknown values in the Spectrum Control database, which
  results in the tier capacity % column to be blank in reports and
  views that contain DS8K capacity information.
  
  RECREATE STEPS:
  Probe a DS8K device running R8.2 firmware with flash drives
  present, observe blank tier capacity % fields in capacity
  reports, in Spectrum Control releases 5.2.13 and prior
