The UTS Global Virtual Tape Demo Program will demonstrate a subset of Virtual Tape Services in a client/server environment.  It is very easy to use and only takes a few minutes to run.  Currently, "The Demo" is available only on mainframe SuSE and RedHat running z/VM or VM/ESA.

To download and install "The Demo" program, do the following in order:

  1. Ftp The Demo program and save it as
    utsg-demo.tar.
  2. Extract the program from the tar ball file using command:
          tar xvf utsg-demo.tar
  3. Place a copy of utsg-demo on your Linux server and client systems.
  4. On your Linux server system, run "The Demo" program (utsg-demo). Via ftp, the program will install the UTS Global TSS packages necessary for the server-side operation of "The Demo", and define ten virtual tapes V00000-V00009.
  5. On the Linux client system, run "The Demo" program (utsg-demo). Via ftp, the program will install the UTS Global packages necessary for the client-side operation of "The Demo". Then, it will prompt you for each of the commands it issues.

To un-install "The Demo", log in as root to run the following program on the server and the client systems:
      /etc/utsg-demo.uninstall

Definitions:
A virtual tape is an emulated magnetic tape residing on disk.   A remote virtual tape is a virtual tape residing at a remote server/system.

Operation:
"The Demo" will utilize approximately 9 MB of disk space on the server system, and 5 MB on the client system.  All allocated disk space will be released when "The Demo" is un-installed.  You must log in as root on both the Linux server and the client systems to run "The Demo".

On the client side, "The Demo" mounts a remote virtual tape and runs a tar command from a directory of your choice. The tar file is stored on the remote virtual tape (on the server). This file can later be archived to real tape using the Virtual Tape Services (VTS) product; but the archive capability is not part of "The Demo".  Then, the remote virtual tape is rewound, and tar is used to list the contents. The program rewinds the tape again, extracts one file of your choice and runs diff to show it is the same as the original file. Finally, the remote virtual tape is un-mounted.

Feedback:
We are very interested in your comments and evaluation.  Has it done its job? Was it easy to run?  Would you please write  to linux@utsglobal.com with any feedback you have.
