FDREPORT Introduction
NEW! FDREPORT Sample Reports Using FDREPORT with Rmm FYI News April 2018

FDREPORT is a z/OS DASD Management reporting tool that reports from a variety of sources, including:

  • VTOCs
  • VVDSs
  • Catalogs
  • DFSMS information
  • ABR control files
  • VSAM
  • Offline volumes
  • CA 1
  • RMM

FDREPORT produces customised reports on DASD-related issues, in detail and/or summary format, and in the form of z/OS batch reports or TSO/ISPF displays. It can be used to create a wide range of useful reports, as illustrated in the Health check section.

FDREPORT is a high-performance reporting tool, which makes efficient use of z/OS resources. It can run during the day without any noticeable impact on other z/OS applications or users. It can typically report on 1,000s of DASD volumes in just a few minutes.


FDRViEWS builds on the foundation of FDREPORT to provide a user-friendly, question-and-answer method of generating reports. It offers a Windows GUI interface, and reports that can be viewed in various graphical formats (graphs, charts etc) or as an Excel spreadsheet. See the FDRViEWS section for more details.
