I can do what I want, thanks for the prompt replies from :-

All provided the same information, and Herve Demarthe provided
a full description which is shown below.
Thanks again to everyone.

Russ,
I have done this kind of things before, though it was on the
same machine, I transfered a disk from scsi 0 slot 3 (rz3) to
scsi 1 slot 1 (rz9).
Some rules and what I did :
1) NEVER use disklabel NOR advfs utilities or commands !
(they will erase advfs information on the disk).
2) The file system was in one piece (/dev/rz3c) and not
spread other several volumes (it can be possible to deal
with this kingd of config also but is perhaps messy).
3) I simply created BY HAND the necessary files under
/etc/fdmns, let's say the file domain is sample :
(I assume that the devices are created with MAKEDEV)
cd /etc/fdmns/sample
ln -s /dev/rz9c rz9c
rm rz3c
reboot (unnecessary if not the system disk. And if you
have Storage Works disks you can do it all "on line" !)
One weirdness (great if somebody can explain it !) :
when the domains are created through dxadvfs, the
links have access rigths : lrwxr-xr-x but when I create
them with ln, they have access rigths : lrwxrwxrwx
AND A SUBSEQUENT "chmod" IS WITHOUT EFFECT !!!
Is it a bug or a feature of chmod applied to links ???
Hope this helps anyway, I think you can easily transpose
the procedure for another machine (you will need to create
the directory /etc/fdmns/sample and to add the entry in
the /etc/fstab file.)
