Overview

The following are the basic parmlib configuration steps.

  1. Setup the VUSSMNTS (VTape USS Mounts) member. This member defines the USS mount points. The sample member VUSSMNTS provided in the PARMLIB library includes a description of each attribute within this member. The <Triplex> section is required and all others are optional.
  2. Setup the groups definitions in the VTGROUPS member. Groups that will write a USS Backstore copy must add the Triplex=USS attribute.

    Note: The Triplex attribute is mutually exclusive with the Export attribute.

  3. Define the names of the VUSSMNTS member in the parmlib <Directory> section of VTPARMS member. Uncomment and add the USSMountPoints attribute to the parmlib <Directory> section. This attribute names the parmlib member containing the VUSSMNTS attributes.
  4. Within the <StartupOptions> section add UnixSystemServices = Y and customize the RootDirectory = '/u/users/vtape' attribute.

    Note: The RootDirectory must already exist.
