Initial Setup

To make use of this facility, there needs to be some initial setup. This involves defining the tape name to be used, defining the tape group name and selecting the tape drives. To facilitate the use of tapes with the TPFxd_ functions, do the following:

  1. Define the ARCHIVE (ACR) tape group using the ZTGRP command on any processor that is using TPFxd_ functions.
  2. Using the ZTDEV command, assign the group ARCHIVE to any tape drives that are going to be used for either input or output TPFxd_ functions.
  3. Using the ZTDEV command, enable automount on tape drives that will be used as output devices.
  4. Define the ARC tape name as both input and output and unblocked, set the generation number to blanks, and assign it to the ARCHIVE tape group through the ZTLBL command.
