IT20343: IBM SPECTRUM CONTROL DISK CAPACITY AND DDM CAPACITY CALCULATION IS WRONG FOR DS8K.

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

• The capacity of the disk is being calculated by 1024 factor
  instead of 1000 factor as is being delivered by the subsystems.
  So in the reports we show a bigger value for the disk capacity.
  If the disk has 1GB we display 1.024GB and 1.049 GiB.

  * PROBLEM DESCRIPTION:                                         *
  * The DS8000 hard disk capacity is calculated wrong in         *
  * Spectrum Control.  The disk size shown with DS8000 DSCLI is  *
  * calculated as GB (10^9).  In Spectrum Control it is wrongly  *
  * displayed as GiB  (2^30).  As result also the Raw Disk       *
  * Capacity of a DS8000 is calculated wrong.                    *
