What you get depends on your controller, disk type, and unit you attach
(basically the machine you create in your SIMH .ini file).

So DJ is a RA60 Disk.

As long as you install it and it works, it doesn't matter.

Your .ini file for SIMH (how you configured your VAX).

Different models allow different hardware, so yes.

If you're using that disk type, yes. But why use that disk type? There's
larger.

Those ISO (actually Files-11 On-Disk Structures ODS-2) should attach to
'cdrom' if I recall.
Here's the microvax3900, all set up.
OpenVMS on VAX setup
set cpu 512M
set cpu idle
set cpu conhalt
Non-volitile memory file goes here
att nvr nvr.bin
Enable disk drives
set rq0 ena
set rq1 ena
set rq2 ena
set rq3 ena
We need a second controller since disks go 0-3, only
4 per controller. This is controller #2
set rqb ena
Disk type RA92 is largest VAX supported disk (1.5g)
set rq0 ra92
set rq1 ra92
set rq2 ra92
set rq3 ra92
This is on the second controller
set rqb0 cdrom
Attach defined drives to local files
attach rq0 disk0.ra92
attach rq1 disk1.ra92
attach rq2 disk2.ra92
attach rq3 disk3.ra92
Attach the install CD to its file (read-only)
attach -r rqb04 VMS_552h4_VAX.iso
VH lines instead of DZ
set vh dhu
set vh ena
set vh hangup
set vh lines=8
attach -uv VH 127.0.0.1:8888,SPEED=*2
TK50 cartridge tape drives (MUA0:)
set tq0 ena
set tq1 dis
set tq2 dis
set tq3 dis
For a printer. Send to a file
set lpt ena
attach lpt printer.txt
RL11/RL01/RL02 Cartridge Disk (RL)
set rl ena
Magnetic tape drive (MSA0:)
set ts ena
Set mac address for 1.10 decnet node.
AA:00:04:00:0C:04 = 1.12 This must be set
before interface is upped. DET XQ to detach.
set xq MAC=AA:00:04:00:0C:04
set xq TYPE=DELQA
attach xq tap:tap2
Start simulator
boot cpu
DUA3 to boot CD-ROM, DUA0 to boot off disk.
>>>set boot dua0 in VMS to set default boot disk
BOOT DUA0

Originally, the .iso was on another controller, but since setup another
disk was needed for swap/pagefile so the cdrom had to move to another
controller.
If you have graphics, the microvax3900 is a good choice because you can
enable the GUI. It also has alot of attachments. The other good one with
alot of devices/attachments is vax8600.
VAX8650
----------------------------------------------------------------
set cpu model=8650
set cpu 512M
set cpu conhalt
set cpu idle
Keep time-of-day clock in a file

set rq3 cdrom
Attach defined drives to local files

This is for the CD-ROM image, as during installation
attach rq3 -r /srv/ftp/pub/operating-systems/vms/disk.iso
VH serial lines using Linux virtual serial ports (tty0tty0 project).
These come in pairs and work like a cable. Due to agetty keeping
tnt0, there are two pairs of lines: one for Linux -> VMS and
one for VMS -> Linux
Linux (agetty) listens via /dev/tnt0, VMS (simh) grabs /dev/tnt1.
This is for VMS to dial into Linux.
Linux can dial in via /dev/tnt2, into VMS /dev/tnt3.
DECUS UUCP uses TXA0 to call *into* Linux.
Taylor UUCP (from Linux) calls *out* and connects to TXA1
Non-UUCP logins work as well, providing they are on the correct port.
set vh dhu,enable
att vh line=0,connect=/dev/tnt1
att vh line=1,connect=/dev/tnt3
Enable tape drives
set tq0 ena

set XU ena
MAC for node 1.11. SCSSYSTEMID number is 1(area) + (1024+node number)
so 1035
set XU MAC=AA:00:04:00:0B:04
set XU TYPE=DELUA
att XU tap:tap1
vax8650 needs "boot rq0" to boot, not "boot cpu"
boot rq0
EOF
The VH lines are black magic to get DECUS UUCP v2 speaking UUCP with
Linux and the rest of the world.
microvax2000 is the only one I've seen so far that will be a VXT (as a
vaxstation2000) and boot off in infoserver.
So, consider the type of system you want to set up. After that, what the
disk gets called isn't so important.
