The summary reports produced by the Tape Drive Simulation
Analysis inquiry will be most useful to you if you specify
the chart reference line option.  This is a high tape
allocation limit beyond which exception reporting will occur.
This could be considered to be the practical limit for
long-term drive allocation.

The value given to this parameter would ordinarily be
somewhat smaller than the number of physical tape drives
actually present in the installation.  Generally, the number
should represent the number of tape drives online to the
system.  RMF data contained in the CA MICS HARDVA Files can
be analyzed to determine this number.  Setting the chart
reference line to 0 causes all data to be printed in the
summary reports.
