2.5.5.2 Inquiry Panels
This section illustrates the inquiry panel entries we made to
create the VSM System Storage and Common Area Storage Usage
Reports to conduct our case study.
SYSTEM STORAGE USAGE REPORT
Figure 2-180 shows the inquiry panel that we used to create
the System Storage Usage Report. (The resulting System
Storage Usage Report is shown in Figure 2-182 in Section
2.5.5.3.) Section 2.5.6.1 presents a detailed description of
each field in the inquiry panel.
The control panel shown in Figure 2-180 specifies that a
System Storage Usage Report is to be created. This report is
designed to assist you in determining the usage of virtual
storage for the system under study. On this panel we
selected the SYSID of the production system and also chose
Zone 1, as this zone represents the prime shift for this
site. Six cycles of the MONTHS timespan of the SCPVSM data
were used in this analysis, as the changes outlined in the
previous section all took place in this time period. Other
zones could have been included in the study, but virtual
storage issues affect the prime shift mainly due to the heavy
usage of online systems.
COMMON AREA STORAGE REPORTS
Figure 2-181 show the inquiry panel that we used to create
the Common Area Storage Usage Report. (The resulting Common
Area Storage Usage Report is shown in Figure 2-183 in Section
2.5.5.3.) Section 2.5.6.2 presents a detailed description of
each field in the inquiry panel.
The control panel shown in Figure 2-181 specifies that a
Common Area Storage Usage Report is to be created. This
report is designed to assist you in determining the usage of
virtual storage in the Common Area for the system under
study. This particular report was chosen because it
amplifies the data shown on the System Storage Usage Report
and permits additional analysis of the virtual storage usage
issues. Because we wanted to parallel the reports, we used
the same data selection criteria for this report as we did
for the System Storage Usage Report. Six cycles of the
MONTHS timespan of the SCPVSM data were also used in this
analysis, as the changes outlined in the previous section all
took place in this time period.
