There are four VMRSDA reports. By default, VMRSDA produces all four reports. You can use different command line options to generate different reports. For example, the VOLUME option will generate VMRSDA reports about a specified volume.

Note: Report numbering begins at Report 2. The Analysis Preface lists 5 reports but Report 1 is marked as "excluded." Use the CP command QUERY NSS to obtain the information previously contained in Report 1.

VMRSDA Analysis Preface

The VMRSDA report file begins with an introductory page titled VMRSDA Analysis Preface. This preface provides information about the command line and input files used, and the reports created by VMRSDA.

VMRSDA Notes, Warnings, and Prescriptions

The second page of the VMRSDA report file provides notes that VMRSDA generated while creating the reports.

Report 2 FORMAT/ALLOCATE Detail Mapping

Report 2 contains information about CP DASD area allocations that were made using the CP FORMAT/ALLOCATE program for each volume. VMRSDA determines this information from the volume allocation map in cylinder 0 (CKD devices) or blocks 0 to 15 (FBA devices) for the volume.

Report 3 VM DASD Detail Mapping

Report 3 is a complete map of your VM DASD system by volume. In this report, VMRSDA consolidates user minidisk allocations under the heading Minidisks to minimize the size of the report and maps all CP-reserved areas in detail. Free space between allocated areas is identified as *Free*.

If a volume is defined on an FBA device, information is provided in 512-byte blocks, with eight FBA blocks equal to one page. For CKD devices, information is generally provided in units of 4K pages, although free space is also converted to cylinders for ease of reference. Report 3 also informs you of any overlaps.

Report 4 List of Other Minidisks

Report 4 lists all minidisks that were not identified as either CP-reserved or CMS minidisks. The report also lists questionable CMS minidisks or minidisks in CA VM:Secure or CA VM:Director HOLD status. The information for this report comes from the VMANAGER MSCDISKS file created by VMRMDS.

Report 5 Volume Allocation Summary

Report 5 summarizes the utilization of each volume. It includes information such as the percent allocated on a volume for CP-reserved and CMS areas as well as the percentage of CMS allocated space in use.
