IT30734: IBM SPECTRUM CONTROL LICENSE COMPLIANCE PANEL DISPLAYS TOO HIGH MANAGED CAPACITY FOR SVC IN COMBINATION WITH XIV.

IBM Spectrum Control 5.3.6 (February 2020)

APAR status

• Closed as program error.

Error description

• Due to incorrect handling of data reduction savings when using
  an SVC or a Storwize family device in combination with backend
  controller having thin provisioning capabilities, the managed
  capacity of a SVC or Storwize device displayed in the license
  compliance panel can be too high. This APAR corrects the
  calculation of capacity virtualized in the SVC or Storwize
  device using only reported consumed capacity from the backend
  controller leading to a lower total and managed capacity.
