Here is what I did to get 2.11BSD over to my 11/44 with an Emulex UC18 SCSI
controller:
(1) Use SIMH to configure/build a working 2.11BSD system from scratch
tapes, if you desire.
(2) Or you can get pre-built 2.11BSD image from here:
http://www.ak6dn.dyndns.org/PDP-11/2.11BSD/
or other locations on the net as well. The image I built is current
thru the latest patches.
(3) Mount the SCSI disk on which you will be installing the 2.11BSD image
on your PC/linux box. Use 'dd' to blast the whole image (from (2)) to the
disk.
(4) Dismount the SCSI disk from your PC/unix box, carry it over to your
PDP-11, install it, and boot it up.
Any way you can do a byte-for-byte copy of the SIMH .dsk file to your
target SCSI drive should probably work.

May be this works wit an CQD220 Controller, but I don't think that this
will work with an Emulex UC07.
The Emulex can partition the disk in some slices, the information where the
partitions are, is somwhere on the disk.
I wrote out Tapes with SIMH to a Unix file and converted those files with
the containing Block length information to a real tape (on some qarter Inch
Tapes with an Tandberg drive [525 MB and up, the smaller Tapes don't
support variable block lenghts]). Done this on FreeBSD.
This way I've created install tapes for 2.11 BSD, RT11, RSX11 and
XXDP.
