John,
I am sorry I wasn't clear. VM and linux are communicating :
When I enter the CP SIGNAL SHUTDOWN command from MAINT linux begins
shutting down. A short time later vm receives the termination from linux
and writes the following message to the vm MAINT log :
HCPSIG2113I User ZORACLE2 has reported successful termination
From a vm standpoint everything appears to be working as designed. It
appears that linux sends the termination response to vm before it has
really completed it's (linux)shutdown. In linux's inittab we have
"shutdown -h" coded.
Thanks, Bob

Like CP SIGNAL SHUTDOWN that triggers the linux's inittab CTRLALTDEL
entry.
What do you mean when you say "linux appears to send a response to VM
saying it has completed shutdown; but apparently it really hasn't "?
Is that sent response just a message on the guest's console or a linux
script doing VMCP MESSAGE userid blah blah blah?
