IT24409: IBM SPECTRUM CONTROL VOLUME CAPACITY CHART SHOWS ACTUAL TIER 0 FLASH CAPACITY AS HISTORICAL DATA .

IBM Spectrum Control V5.2.17 (May 2018)

APAR status

• Closed as program error.

Error description

• The current values for volume metrics "Tier 0 Flash Capacity
  (GiB)" and "Tier 1 Flash Capacity (GiB)" are shown for the
  historical values as well
  after upgrading Spectrum Control to 5.2.15, 5.2.15.2 or 5.2.16
  even if before the upgrade the historical values were different.
  Before 5.2.15, 5.2.15.2 or 5.2.16, those metrics were loaded
  from some fields from
  T_RES_TIERING_INFO_SNAPSHOT_GENERIC_SSD_VIEW
  which is a view based on T_RES_TIERING_INFO_SNAPSHOT which has
  the historical capacity information.
  In 5.2.15, 5.2.15.2 or 5.2.16, those metrics are loaded from
  T_STORAGE_VOLUME, where there is no such historical information,
  just the current values for those metrics.
