What undesirable may AUTO_ACTION = RESTART bring to?

Hello managers (and somebody of DEC people I hope),

I know it's HALT always recommended. Newertheless I have a heavy motivation
to reboot the system automatically in the case of crash while keeping the
possibility to enter in console when I need (executing shutdown -h or init 0
for example). In the documentation I didn't see a definite answer whether
the purpose is achieved with setting AUTO_ACTION = RESTART. Besides, I have
looked through all (eight) messages in the archive concerning RESTART action
but yet didn't find what I need.

I'm thinking over setting AUTO_ACTION = RESTART for our old DEC 2000 model
300 having experienced four crashes - by two different reasons (as far as
I can judge by appearances of the stack in crash-data, inevitable with "kernel
memory fault"). I perceive that RESTART may be considered only as a palliative,
nevertheless I have to minimize the inconvenience for our users in the case of
the system crash.

So, I see in Customer Technical Information:

5-12:
RESTART The system boots automatically when it is turned on or after it fails.
(It's all).

1-3:
The system enters and remains in the Open VMS and OSF/1 console under the
following conditions:
- When AUTO_ACTION is set to HALT and OS_TYPE is set either to VMS or to OSF.
- When power-up tests fail.
(No other opportunities pointed).

From 5-12 I can conclude that under AUTO_ACTION = RESTART after crash the
system reboots. Meanwhile I want after shutdown -h the system to enter (and
remain) in console but from 1-3 it follows (the first part of the first
condition is false) that I get to console only if tests fail.
 
So, what I get executing shutdown -h? (I wouldn't like to investigate it in
such experimenting, especially when the result is unpredictable. Eventually,
it's the documentation that should say it).

The system is 3.2c, DEC 2000 model 300.
What annoying result does RESTART imply?

Thanks,
Irene
