Check the permissions and ownership of the underlying raw devices. You may have to wade thru multiple levels of links, but it is the raw devices you have to modify. Thee permission must be rw-rw---- for each device and the owner and group must be informix.

Ok, I will try to explain what I did and where I stand.
Both systems are identical hardware. I will call the production system that
the backup was taken from PROD and the new system that I am trying to restore
it to BAK.
On Prod, the settings are:
Servername - courtshm
Onconfig - onconfig.courtshm
Everything works just fine.
On BAK, the system was supposed to be a mirror of PROD (and it was for the
most part, /etc/services entry withstanding)
The chunks are raw devices referenced as links, the links are identical on
both systems.
I modified the onconfig file as follows (before attempting restore)
Changed the name to onconfig.courtsbak
changed servername to courtsbak
I modified env variables for informixserver and onconfig to reference
courtsbak & onconfig.courtsbak.
I modified sqlhosts to reference courtsbak name
I left the tapedev the same so it would point to the backup 'file' created by
ontape from PROD
Executed 'ontape -r' (a 2nd time after adding the sqlexec entry to
/etc/services)
Received the "oninit: Fatal error in shared memory creation" error as I posted
last night. Went home and left it.
This morning, the prompt returned so I did an 'onstat -' to see where I was.
It showed block checkpoint, so I shut down server, changed tapedev to
/dev/null and did the oninit and get the following:

Hi,
with the instances being on different machines this is not a strict
requirement.
However, it might be good practice to have a clear one-to-one correlation of
the onconfig file to the IDS instance. One way of doing that is by naming the
onconfig file with the instance's server name - in which case you would
actually want to change the name of the onconfig file. And then you'd have to
change the setting of the ONCONFIG environment variable as well ... :)
Regards,
Martin
