I can boot the installation DVD V8.3-1H1 with a USB Blu-Ray device:

 vms_loader
......................................................................................................................

%VMS_LOADER-W-Conout device path cannot be set to multiple devices
%VMS_LOADER-I-Select Console Device Paths from the Boot Manager Menu.

    ****************************************************************

    You can install or upgrade the OpenVMS I64 operating system
    or you can install or upgrade layered products that are included
    on the OpenVMS I64 distribution media (CD/DVD).

    You can also execute DCL commands and procedures to perform
    "standalone" tasks, such as backing up the system disk.

    Please choose one of the following:

        1)  Upgrade, install or reconfigure OpenVMS I64 Version
V8.3-1H1
        2)  Display layered products that this procedure can install
        3)  Install or upgrade layered products
        4)  Show installed products
        5)  Reconfigure installed products
        6)  Remove installed products
        7)  Find, Install or Undo patches; Show or Delete Recovery
Data
        8)  Execute DCL commands and procedures
        9)  Shut down this system

The dot in the beginning indicate the load of the memorydisk (-flag x,
200000).
The DNA device goes offline and comes back.

The remastered DVD V8.4 (Original + Remastered) behaves different:

and never comes back
