Yes, I am using 10.1
I'm not sure if anyone has actually attempted what
you're doing, some of us
were discussing this a year or two ago, but I know I've not had time to try
it.
I tried all the obvious combinations for imaging the hard disk, the
final one being:
SIMH using the SCSI drive as a block device (Linux: attach rq
/dev/sdc) and confirming that SIMH boots the drive successfully after
the install, however on re-attaching to the 11/93 it still throws the
Drive not ready error when trying to boot.
Of course you may simply have some sort of hardware
issue going on there as
well, I'm not familiar with the RQZX1.
The drives passes the built-in RQZX1 diagnostics, which includes
read/write/verify tests etc. I formatted the SCSI drive via the RQZX1
too (prior to using the drive on Linux via SIMH to install RSTS/E),
just in case the format process was doing something special (although
I can't imagine what since I understand MSCP masks drive specifics).
A next posible step is to use this source-code for a MSCP boot so I
can catch the initial boot load and see what is in the first disk
block (containing the next level bootstrap):

I will also try a different model of SCSI drive too - perhaps the
Quantum Fireball is too much of a good thing (4200RPM 2.1GB); I have
an old clunker of a Quantum ProDrive 80S (3600 RPM 80MB!)
Does anyone know how SCSI ID's are mapped to MSCP LUNs? so far the
RQZX1 appears to map the first SCSI ID (in my case #4) to LUN 0 (which
is what I want) - I am assuming it just does them in sequence.

Well the ProDrive was too small (although pleasingly quiet) RSTS/E
failed with an out of space error during install - I suspect I need to
modify the install defaults to move things around to fit such a
"small" drive.
I switched to a Seagate 1.2GB, used SIMH to build another RSTS/E
system, re-attached to the 11/93 and it now "almost" booted, which is
progress at last. Some strange characters appeared during the
second-stage boot and then the "Pack cluster size" error appeared and
it looped at this point.
So I appear to be encountering some sort of disk layout/sizing
problem. I used the default cluster size of 8 and 64 with the same
results.

Pack cluster size is not 1, 2, 4, 8, 16, 32 or 64.

Do you happen to have any DEC RZ2x HD's? I'd recommend giving those
a try. While RSTS/E 10.1 doesn't require these, it is possible that
the RQZX1 does, or the combination of the board and RSTS/E does.
RSTS/E can be touchy. I was totally unable to install DECnet/E from
4mm DAT using a TLZ06, even though I installed RSTS/E 10.1 that way.
On the other hand the install worked just fine using a TK50 and TKZ30
drive.
Personally I'm using a PDP-11/73, Viking QDT, a 50-pin 2GB Seagate
Barracuda SCSI HD, and a Plextor 8x Caddy CD-ROM drive to run 10.1.
