creating device special files

We just got a brand new system in (ES45 running 5.1a), and going through the
configuration process, I came across a question. All of our systems have access
to all of the disks out on the SAN. All of the systems see these disks as
different names (one system might call a given disk "dsk10", while another
system will call it "dsk23". I want to have this new system match device
numbers with one of the other servers. I found the nice "dsfmgr" command to be
capable of renaming a disk (swapping out the device special files for a disk).
The thing that I've run into though, is that it will only work if both sets of
device special files exist on the system (so renaming dsk5 to dsk4 works great,
but if I want to rename dsk4 to dsk47 (and there are no dsk47 device special
files), it will not work.

So basically I'm wondering how I can create new device special files for
non-existent disks? Is this possible? This system sees disks 0 through dsk33.
I need some of the disks to be renamed with numbers higher than 33 so that it
matches the other system (for example, dsk6 needs to be dsk34). Any help would
be wonderful. TIA
