Partitioning / Cell Server setup questions

[Sanjay Tailor_1]

Hello All,

I have just had a used rp7410 server installed which has 8 processors and 8GB of RAM. When I logged into the GSP, I found that the server was partitioned with one partition, 0. I booted the partition which came up with HP-UX 11.11

But when I ran top and ioscan, I found only 4 processors and it seemed to be running all 8GB of memory. I went back to the GSP but found navigating and getting information a bit difficult. Is there a place in the GSP where I can see all the hardware in the server ie the 8 processors?

I would like a single server with all 8 processors and memory. Do I have to destroy the old partition? Add to the existing partition? Where and how do I make those changes / deletions / additions? How will HP-UX react to that? I suspect it will be OK with 4 more processors. If I destroy the partition, then will I lose the OS?

Is there a document out there which may explain the terminology of partitioning as I am not familiar with that.

Any other advice / help is much appreciated.

Thanks,

Sanjay.

This is the documentation about nPartitions.

To find informations about the CPU, go to the MP and run

MP:CM>ps

and select cabinet, cell

or run the info tool of the online diags against the system item. This will show you how many CPUs are installed, configured, enabled ...

Hello,

Thanks for the replies. I already have the nPartitions Guide. I am slowly going through it.

Thanks,

Sanjay.

If you boot to the one partition you can export your DISPLAY and run /opt/parmgr/bin/parmgr

Its a Xwindows utility that allows you to configure NPARs. It should show hardware thats not been assigned to an npar or allow you to create a new one.

I'm assuming you have two core cellboards in there, one with all the memory and the second has the just 4 cpus?

The command

parstatus

will give you almost the same result like the online diags info tool.

You will see the total number of present, configured and deconfigured CPUs per cell and a lot more information.
