Yes.  SimH version:

VAX simulator V3.9-0
sim> show version
VAX simulator V3.9-0 [64b data, 64b addresses, Ethernet support]

Here are the setup details for a shadowed disk I have under SimH:

In the SimH startup file:

-----------
set rqd0 rauser=6000
set rqd1 rauser=6000

.
.
.

att rqd0 data/dud0.dsk
att rqd1 /media/simh-data/dud1.dsk
-----------

at the Linux prompt:

$ ls -lh data/dud0.dsk
-rw-rw-r-- 1 simh simh 5.6G 2012-05-18 17:01 data/dud0.dsk

Within VMS:

$ write sys$output f$getdvi("DSA103:","maxblock")
11724000

Note: If you modify the size of a disk within the SimH startup parameter 
file between runs, you should assume that you cannot read the existing 
contents of that disk under VMS on the next run.  A better course of 
action is to create a brand new disk and transfer the old disk's data
onto the new one.
