3.2.8 Direct Access Media Reliability Report

The Direct Access Media Reliability Report provides a summary
of the reliability of direct access volumes for a selected
current period and a previous period of time. The report
provides a measure of the media reliability in terms of the
usage per failure encountered on the volume.  See Section
3.1.8 for more information.

----------------------------------------
Notes:

     1.  CURRENT may specify a single date or range of dates.
         The default is to process data from yesterday only.
     2.  PREVIOUS may specify a single date or range of
         dates.  The default is to process data from the week
         prior to yesterday.
     3.  Valid TIMESPAN values are DETAIL and DAYS.  The
         default is DAYS.
     4.  CYCLES may have any value.  Note that the report
         will attempt to select data from the date ranges
         created by processing the CURRENT, PREVIOUS, and
         DAYRANGE parameters.
     5.  DAYRANGE can have any value up to its maximum
         allowed value.  The default is 7 days.
     6.  The keywords SYSID and CPUSER may be used to limit
         the data to be selected.
     7.  The keywords TYPE and ADDRESS may be used to limit
         the data to be selected.
     8.  The keyword VOLUME may be used to select one or more
         volumes to be processed.
     9.  If other keywords are used, they MAY AFFECT the
         report.  They are NOT ignored by the report.

The processing dates and ranges are calculated in the
following manner:

CURRENT period      if the CURRENT keyword is not used, the
                    current period consists of the data from
                    yesterday's date.

                    if CURRENT enddate is specified, the
                    current period consists of the data from
                    the specified enddate.

                    if CURRENT startdate,enddate is specified
                    the current period consists of the data
                    in the range startdate to enddate.


PREVIOUS period     if the PREVIOUS keyword is not used, the
                    previous enddate is set to the date
                    before yesterday's date.

                    if PREVIOUS enddate is specified, it is
                    used as the previous enddate.

                       startdate is calculated by subtracting
                       the value for DAYRANGE.  The previous
                       period is

                          startdate-DAYRANGE+1 to enddate

                    if PREVIOUS startdate,enddate is
                    specified, it is used as the previous
                    period.

The current and previous periods must not overlap.  If the
parameters cause an overlap to occur, data will be selected
for the current period first and then the previous period.
