You might want to check your license situation. Our second CPU came
with an add-on PAK with 100 units for OSF-BASE, and all went smoothly.
Our third CPU came with a VMS license; this didn't work at all :-).

Details are too embarassing to relate, and probably you'll be far
smarter than I was about this...

We've been doing a bunch of this lately.  It's pretty simple - If you're
buying the CPU module from a reputable dealer, you'll even get a handy
little instruction booklet detailing the steps.  :-)
Of course, the new CPU module you buy needs to be a 190MHz unit, just like
the one presently in your system.  If I remember correctly, the order
number for a 190MHz CPU module for Digital Unix is 450AR-AA...
Here's a thumbnail sketch of what we do:
1. Shutdown system
2. Once in console mode, issue a clear_error cpu0 command (Guess you should
do this for each CPU you have in the system already)
3. Install the new module in an appropriate slot.
4. Power up with the halt button in, and issue a show fru command.  If you
can enter this command (ie, the system doesn't hang on powerup), and you
see the proper number of CPUs, the hardware part of the task is done.
5. Boot Digital Unix.
6. Taking the license PAK that came with the new CPU, use the lmf utility
to add sufficient points so that Digital Unix will start the CPU on the
next reboot.
7. Reboot.  Use something like vmubc to make sure both CPUs are being used.
8. One word:  Lunch!   :-)
                    Hope this helps,
                            Ed

Hello,
Make sure you have the license for multiple CPU's.  (Yep, Digital sells
a license for that too!)  That is the standard OSF-BASE PAK but for MP
machines.

Make sure the error count on the 1st cpu board has been cleared out.
I can't recall the command for doing that right now, but you handle it
from the boot monitor.
