/OWNER_UIC=uic Specifies an owner user identification code (UIC) for the volume. The default is your default UIC. Specify the UIC using standard UIC format as described in the VSI OpenVMS Guide to System Security. For magnetic tapes, no UIC is written unless protection on the magnetic tape is specified. If protection is specified, but no owner UIC is specified, your current UIC is assigned ownership of the volume.
