The CUA function allows you to set policy names outboard using keywords. If GRPNAME is specified on the CUA invocation and the volume is a private volume residing in a library with outboard policy management support, the valid storage group name specified in GRPNAME is assigned as the volume's outboard storage group policy. If GRPNAME is not specified, the TCDB storage group name is assigned as the private volume's outboard storage group policy (PRIVATE to PRIVATE CUA).

You can use the SCNAME, MCNAME, and DCNAME keywords to specify values for policy names for the storage class, management class, and data class constructs. One or more of these options can be specified. The fourth policy construct is specified using the existing GRPNAME option. The GETPOLICY keyword cannot be specified at the same time as the GRPNAME, SCNAME, MCNAME, and DCNAME options.

For a scratch volume, the CUA function sets the default policy names outboard; these names consist of blanks. The GRPNAME, SCNAME, MCNAME, and DCNAME options are ignored on SCRATCH-to-SCRATCH and PRIVATE-to-SCRATCH CUA invocations, as scratch volumes are always assigned default policy names.
