APAR status

• Closed as program error.

Error description

• The values shown in the TPC pre-defined reports with the "By
  Port" filter are incorrect and
  might be several orders of magnitude bigger than what they
  actually are for all DS8k's, regardless or model and mcode
  level.
  In contrast, the equivalent "By Port" performance reports for
  the same DS8k's in the TPC standalone GUI show correct values.
  For example, the value of 108 ops/s for "Port Send I/O Rate"
  reported in the standalone GUI might incorrectly show as 6532
  ops/s in the pre-defined reports.
  The pre-defined reports are accessed via the path: TPC Web GUI
  -> Reporting -> Click Pre-defined Report -> Storage -> Ds8k ->
  By Port.
  The standalone GUI reports are accessed via: TPC standalone GUI
  -> Disk Manager -> Performance -> By Storage -> By Port
  
  The problem does not exist for other storage systems.
  The fix will correct the performance Cognos model in order to
  retrieve the correct values for the port metrics for DS8k's.

Problem conclusion

• The fix will correct the performance Cognos model in order to
  retrieve the correct values for the port metrics for DS8Ks.  The
  fix for this APAR is targeted for the following maintenance
  package:
  
  | refresh pack | 5.2-TIV-TPC-RP0006 - target June 2015
  
  http://www-01.ibm.com/support/docview.wss?&uid=swg21320822
  
  The target dates for future refresh packs do not represent a
  formal commitment by IBM. The dates are subject to change
