The DASD Installation Overview Report provides the data center manager with a one-page report showing key areas of DASD space management. The report is a composite of seven sections, each related to DASD space considerations: o Configuration Totals o Data Set Size Analysis o Data Set Fragmentation Analysis o Data Set Last Reference Analysis o Largest Consumers of DASD Space o Largest Over-Allocated Consumers of DASD Space o Exception Analysis A sample report follows.

Figure 3-1. DASD Installation Overview Report Configuration Totals Section This section gives configuration totals for the number of data sets allocated. It also provides totals for the number of DASD tracks in the system (capacity), tracks allocated, and tracks in use. Data set and volume counts are also reported based on whether the volume or data set is being managed by System Managed Storage (SMS). Data Set Size Analysis Section This section groups data sets into one of five groups according to data set size. For each group, totals are produced for the count of data sets in the group. The data set count is also expressed as a percentage of the total data set count, as reported in the Configuration Totals section. The data in this section is useful in determining the number of data sets that have a large amount of space allocated. Data Set Fragmentation Analysis Section This section groups data sets according to the number of extents they have allocated. The number of extents allocated is divided into three groups. For each group, totals are produced for the count of data sets and the amount of space allocated. The space allocated is also listed as a percentage of the total DASD space as reported in the Configuration Totals section. The data in this section shows how many data sets are inefficiently allocated. Data Set Last Reference Analysis Section This section groups data sets into one of five groups according to the last date referenced. For each group, totals are produced for the count of data sets and the amount of space allocated. The space allocated is also listed as a percentage of the total DASD space, as reported in the Configuration Totals section. The data in this section is useful in determining how much DASD space is allocated to infrequently used data sets. Largest Consumers of DASD Space Section This section of the report lists the high-level account code for the five largest users of DASD space. The data is ordered according to the amount of DASD space allocated. For each account code, totals are produced for data set count and space allocated. The space allocated is also listed as a percentage of the total DASD space as reported in the Configuration Totals section. The last line of the section contains totals for the five accounts listed. The data in this section shows which accounts have the largest impact on DASD space allocation. Largest Over-Allocated Consumers of DASD Space Section This section lists the high-level account code for the five users of DASD space who have the most allocated space not in use. The data is ordered according to the percentage of allocated space not in use. For each account code, totals are produced for space allocated and space used. The space allocated is also listed as a percentage of the total DASD space as reported in the Configuration Totals section. Additionally, the space used is listed as a percentage of the space allocated. The last line of the section contains totals for the five accounts listed. This data is useful in determining which accounts have the largest amounts of space not in use. Exception Analysis Section This section lists the status of the five most critical exceptions that have been defined in the VCA information area. A count of the number of volumes that have generated each exception is also produced. The data in this section is useful in obtaining the status of the five areas you think are most critical for your site. Tailoring Options See Section 3.8.3 of this guide to see how to customize the information on the report to better meet your needs.
