Description of the Threshold Summary Report

The data in the threshold summary report is grouped by tape subsystem. The report has four sections as shown in the following table:

SECTION DESCRIPTION
DEV(ice) STATISTICS Shows one line of statistical and error data for every demount record whose error count exceeds the read or write threshold you coded on the report parameter.
PERMANENT ERROR SUMMARY Shows a one-line entry for every permanent error. A permanent error can be a read error, a write error, or an equipment check. This section ignores threshold settings so there are no limits.
TEMPORARY ERROR SUMMARY Shows a summary of all temporary errors recorded for each device number or CUA, whether they exceeded your threshold or not.
VOLUME STATISTICS Shows the errors and usage statistics by volume serial number using each MDR and OBR record from the first three sections of the report. This section also ignores threshold settings so there are no limits.
Note:
  • The first three sections appear once for each processor in your installation.
  • The columns in the fourth section of the report are titled differently depending on the device type involved.
  • See Threshold Summary Report Information for how the columns differ and for the device types supported by the threshold summary reports.
  • Information for up to 256 CPUs can be provided in the threshold summary.
  • It is possible to have multiple internal processors reported under one serial number and thus increase EREP’s capabilities. See SYSIMG Control Statement for details.
