2.3.7 Requirements

The Auxiliary Storage Management reports give you the
capability to track the allocation of auxiliary storage on a
monthly, weekly, daily, hourly, or interval basis.

The reports use data from the page/swap data set files and
from the device activity files from the RMF SCP and HAR
Information Areas to report on the activity levels and
response of the ASM subsystem.  The device activity files are
also used to add in the I/O queue time for each of the
page/swap devices, because the I/O service time in the
page/swap files includes only the I/O transfer time.  Figure
2-81 shows the CA MICS files and timespan levels that are
required to produce the ASM Analysis reports.

  Figure 2-81. ASM Analysis CA MICS File Requirements


For the CA MICS HARDVA and HARPSD Files, only one level is
required (i.e., DETAIL, DAYS, WEEKS, or MONTHS), depending on
the timespan you specify during inquiry definition.

The number of cycles maintained at your installation for each
of the CA MICS files in Figure 2-81 determines the time frame
for which you may produce ASM Analysis reports and plots.
