XQUERY volume pace report

The following report is an example of an XQUERY volume pace report that is generated by the XQUERY S1 V(ALL) PACE command.

Workload-based write pacing

When workload-based write pacing is in effect, the XQUERY volume pace report has these differences:
  • It is labeled as REPORT 003, rather than REPORT 002
  • Lines are added for the statistics of the levels of the write activity within the volumes.
  • The values for RES RATE, WRT RATE, and PACE MS on the detail lines are the total values for the volume.
  • When workload-based write pacing is in effect for a storage controller, the threshold count (THD CNT) column separator is changed from : to @, and the value after this separator is the setting for the write pacing level from an XADDPAIR or XSET command, not necessarily the level at which the volume is being paced.
  • An additional detail line is shown for each WLM pacing level (WLM1-WLM6) that identifies what WLM importance levels are getting written to the volume, and the differentiated pacing in effect.
Note: With the additional information for workload-based write pacing, the number of lines in the XQUERY VOLUME PACE report may increase significantly.
