configure new cell board

It is my first time to manage rp7410 servers.
I want to add one more cell board containing two CPUs and 8GB memories to an existing rp7410 box. HP CE told me that I should configure new cell board to be integrated with existing box.

Please help me to configure new cell board.

Re: configure new cell board

Hi Brian,

What the CE is telling you is that the cell boards should be balanced - i.e. same # of CPUs & memory count between them.
So if you have 2CPU & 8 GB on the original cell board, then you're OK. If not then balance them on the install of the second.

HTH,
Jeff

Re: configure new cell board

There are 4 CPUs and 16 GB memories in an orignal cell board.
What am I supposed to do then ?

Re: configure new cell board

Hi Brian,

My earlier advice was based on the assumption that you're not using nPars - hard partitions. If you are then what you need for each partition will dictate how to populate the cell-boards.

If however you intend to have a single partition, then you should populate them both with 3 CPUs & 12 GB memory each I'd believe.

Re: configure new cell board

Are you sure that I have to distribute CPU and Memories equally on both cell boards ?

The reason why I am asking you this is that we have two RP7410 servers wich have two cell boards, 6 CPU and 6 GB Memories.
However, one cell board has 4 CPU and 4 GB memories and the other one has 2 CPU and 2 GB memories. They have only one partition
on both boxes.

This conflicts with your answer.

Re: configure new cell board

Hi Brian,

No it's not required, but recommended for performance reasons. Mainly the memory should be balanced for interleaving to have maximum benefit. But I believe balancing the CPUs also has a benefit as well.
I'm sure an HP HW guru will chime in & give us a definitive answer.

Re: configure new cell board

Consequently, you mean that the system can recognize new cell board without configuring anything if it has only one partition.
Is that right ?

Re: configure new cell board

It is recommended by HP for performances reasons and for interleaving that all cell boards making a partition be of the same type i.e , same number of cpus , memory , dimms in the same slot even the same firmware .

Once done you can use the gui partition manager at /opt/parmgr/bin/parmagr to add the new cell board in the partition .

Re: configure new cell board

Do you have a manual for the gui partition manager ?
If you attach it there, I really appreciate it.

Hi Brian,

Here's a link to the HP Systems Partition Guide for nPartitions:

Re: configure new cell board

go into the MP and enter the command menu (CM)

type DU

This will give a display of what you have installed in your chassis. if there is a star under both cell boards, then the cell is recognized.

go back to hpux, and use the parstatus command to make sure the OS can see the cell board. (this command gives several pages of output, IIRC)
also, parstatus will show you which cell needs to be added to the partition.

now do a:

man parmodify

this is the command that will add the cell to your existing partition.


the command is like this:
parmodify -p 0 -a 0:base:y:ri

the number following the -a option is the cell number to be added.

What are the chances...
