IT40449: TOTAL CAPACITY SAVINGS VALUE IS INCORRECT IN STORAGE INSIGHTS

APAR status

• Closed as program error.

Error description

• The value shown for the Total Capacity Savings value in Storage
  Insights is incorrect.  How the drive compression is counted in
  the calculation for the Total Savings may vary.
  
  In one example, we found that the drive compression was
  counted twice.  It may vary on other FlashSystem storage.
  
  Expected:
  Total Savings = Deduplication + Thin Provisioning + Drive
  Compression + Pool Compression
  
  Note: This issues is about the Total Savings value.  Total
  Capacity in the details is correct.
