Adding a CPU to rp8420 npar

[Debbie Beresford]

I have an RP8420 with 2 cells.  I am assuming they are npars because I can use the command parstatus but not vparstatus.  Cell 1 has a dual core CPU that is not active.  I need to activate this.  Below is a portion of parstatus.  I have highlighted the cell in question.  The more I research, the more confused I get. 

My questions are as follows:

1.  Can this be done with the system up?  If so, I would reboot after anyway just to make sure everything looks ok.

2.  Is this done from the system prompt or from the MP?

3.  I found a command parmodify -p 1 -a cpu::1  Is this what i would use?

4.  Is there any configuration required afterwards or should it be recognized automatically.

Any help is appreciated.
