I find SIMH to be an invaluable tool, especially under Linix. For the SCSI VAXen, if you
have (or put) a SCSI card in your Linux box, you can point the SIMH definition at the
raw device and actually mount the physical drive under the simulator. You can even boot
from it if you have virtual hardware defined which is close enough to what is expected.
Or - you can DD the drive into a big file and point SIMH at that - it's much easier to
recopy a file than to rewrite a drive - so when I want to screw around with "dangerous"
things, I tend to do it on a file copy of the drive under SIMH.
Finally, once you get your drive into an image, you can burn it to a CD and mount it
(or even boot it if it's a stand-alone-backup disk) from a CD drive on you real VAX.
(I happen to do this by transfering the disk image to a windows box where I use NERO
to burn it - Say NO when it asks if you want to "fix" the identifier bytes in the ISO
which it doesn't think look right! Using SIMH, you can make a 650M disk, copy all the
stuff you want from your real drives, and then turn that image to a CD which makes for
an easy way to make VAX readable backup disks.

Very strange - I've had to reset the passwords on a couple of my VMS system when I got them,
and it's always worked for me.

If you are configured for a serial console as OPA0:, you can log in as SYSTEM without
having to have a valid VMS license on the system.
>they put the units=0 which bothers
I have several VMS licenses which have units=0 and they all work fine. I did read somewhere
that it's supposed to have UNITS= "at least 100", but I have no idea what this is for/means.
The only VMS license I have which has a non-zero UNITS is a VAXstation only (ACTIVITY=D)
which has UNITS=200 ...
> me. or the pwdchange=pre-expired is the culprit.
Doesn't pre-expired just mean that it will force you to change it the next time
you log on. Ie, it's already expired rather than having to wait for the 30 days
or whatever the expiry time is set to on your system. I don't think it makes the
password invalid, just marks it as expired so that you will have to change it.
