[Simh] Simh VAX V3.9-0 Problems using Init command

[will kranz]

I'm currently running OpenVMS 073.
I did this a week ago on a different machine (not accessable today) and it worked fine.I have a bootable vms073.dsk image, and I created two empty files per below to be initialized.
in vax.ini I had:attach RQ0  vms073.dsk
attach RQ3  rx50.dskattach RL0  rl01.dsk
Then started emulate and booted CPU followed by:
b DUA0works fine, and I log in.
last week I believe I just did following to create bare disk image files just containing system files:init DUA3: VRX50init DLA0: VRL01
This week the init fails, and I am told "%INIT-F-MEDOFL, medium is offline"
but the result for "sh dev" for these devices is:SIMH1$DUA3:             Online               0
SIMH1$DLA0:             Online               0
I am puzzled as to why this doesn't work now.  What am I missing here?Thanks in advance.
