5.3.3.3 HSMTAP Usage Considerations

This section identifies any special considerations or
techniques related to using the HSMTAP file.

Suggest You Keep Many Cycles

Generating support for many cycles of the HSMTAP file will
enable you to graph the change in tape utilization by DFHSM
over a long period of time.

This file contains only one small observation per inventory
of DFHSM.  Normally, this inventory will only occur once per
day.  Therefore, because of this extremely low resource
consumption we recommend you keep many cycles of this file at
either the DETAIL or DAYS time-span.  If you choose DAYS for
the location of the many cycles, then DETAIL should be set to
only a few cycles (and vice versa).
