Error description

• DS8870 EasyTier tier capacity metrics are incorrectly reported
  in TPC - The problem is observed when a user views the "Tier
  Capacity SSD" metric (which explains how much data of a specific
  volume is on SSD/Flash), the reported metric in TPC's
  reports/views is much larger than what the volume has actually
  used.
  In an observed case, a volume <volume_name> (volume id <xxx>)
  was known to have used 6GB; but TPC's Tier Capacity SSD metric
  shows that 430GB is on SSD/Flash.
  RECREATE STEPS:
  Observe incorrect "tier capacity ssd" values in various TPC
  reports
